97% of dieters are just looking for a weight-loss product that works. Yeah, we’re not sure about the other 3%, either. We wanted to learn more about HCG Activator, so we focused on the ingredients, side effects, research and customer service. Additionally, we read hundreds of reviews, comments and complaints online. Then, we summarized and refined to give you the  info you need.

HCG Activator Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What is HCG Activator?

Firstly, HCG Activator is a dietary supplement that’s touted as an alternative to hCG products. The ingredients include green tea leaf extract, l-arginine, l-ornithine, N-acetyl-l-carnitine, black cohosh, saffron and huperzine. You’ll take two capsules, twice per day on an empty stomach. Supposedly, it reduces hunger and eliminates water weight. [1]

HCG Activator was introduced by BioGenetic Laboratories; although there’s no mention as to when the company was founded. The supplement is sold through the official website and trusted retailers. We like that it contains a few natural ingredients and that we located some positive customer comments, but read on…

Price –”Is Anything Cheaper than HCG Activator?”

Our first concern with this product was the high cost of taking HCG Activator. “At 79.99 per bottle and several pills per day, the monthly cost can quickly reach $100-150,” said our Research Editor. “Cheaper alternatives that offer proven results are readily available.”

“Too expensive for a ‘fad’ diet,” said one user. [2]

“With all the mixed results in online reviews, this product is too expensive for me,” explained another.

According to some HCG Activator reviews, cost wasn’t always a consideration.

“Decided to try HCG Activator because it was much less costly than those other programs,” said a dieter.

Meal Plan – “Very Low Calorie”

Another concern was HCG Activator side effects from eating 500 calories per day. “I took HCG Activator for 1 week before realizing that it wasn’t healthy for me to sustain a 500 calorie diet,” said one dieter. [3]

“I was constantly hungry, had stomach pain and nausea, experienced jitters and shakiness, and I didn’t lose weight,” said another.

One nutritionist said,“Nobody should be on a diet that forces you to consume less than 1200 calories per day for females or 1500 calories per day for males. It outweighs the benefits of modest weight-loss.”

We found that some dieters didn’t complain about the eating plan with HCG Activator. [4]

“Many other weight loss programs require you to buy their foods. The foods on this list are foods I have eaten for years, nothing weird,” stated a customer.

“The diet is strict but easy enough to follow. I was never hungry,” commented another.

Our researchers have shown that whenever a program has a particular aspect that is especially difficult (painful workout routine, harmful side effects, long term concerns, bad taste, etc.), the likelihood of losing weight and keeping it off is slim. If HCG Activator really does promote an unsafe diet and has these negative side effects, it could make it difficult for dieters to reach their weight-loss goals. [5]

The Science – “Convincing Evidence?”

HCG Activator makes a lot of claims that are unsubstantiated and are missing critical research. The product says it will quickly help you slim down and lose excess weight, but the majority of the weight-loss may be attributed to the meal plan that leaves dieters hungry. We couldn’t find any research on the formula. Here at DietSpotlight, it takes science to convince us to suggest a product. We found nothing for this supplement. [6]

The Bottom Line – Does HCG Activator Work?

Is it time to race out for this one? We do like that HCG Activator has been around for over 10 years, that the products are available online and at various health food stores and that the ingredients are easy to find online. Unfortunately these positives are outweighed by the missing research, so we are skeptical about suggesting the supplement or diet. We’re also concerned about the potential side effects and hunger.

If you’d like to slim down and reach your goal weight, we suggest you go with a product that offers proven weight-loss at an affordable price. One that will have claims backed by research and clinical studies and won’t have long term health concerns.

Among the best products we’ve seen this year is one called Leptigen. The proprietary blend of four ingredients has been featured in clinical studies, and has outperformed a placebo when it comes to helping increase fat burning and boosting metabolism. Users online agree that it offers great weight-loss results without the harmful side effects and long term health concerns.

Right now, Leptigen is also available through a Special Trial Offer, which shows that the makers are confident that you’ll like the product.

Previous HCG Activator Review (Updated December 13, 2011):

What You Should Know about HCG Activator

The HCG Activator is a BioGenics supplement sold by GNC and other online retailers. The supplement claims to boost HCG to promote weight loss. HCG is human chorionic gonadotropin, also known as the pregnancy hormone. The body releases HCG when a woman becomes pregnant. Many supplement companies claim HCG promotes weight loss, but most do not bother with clinical proof of these claims.

HCG Activator is an affiliate product. This means many people publish websites selling the product. These websites are individually owned and neither BioGenics nor GNC have any control over the information and claims made on the website.

HCG Activator sells for $79.99 per bottle. This is far higher than other diet supplements in the same category.

List of HCG Activator Ingredients

Human Chorionic Gonadotropin GlycoPeptide Stimulating Complex: L-Arginine, N-Acetyl L-Carnitine, L-Ornithine, Green Tea Leaf Extract, Saffron Extract, Black Cohosh and Huperzine.

Product Features

L-arginine is an antioxidant that works to reduce oxidant damage in the body. Unlike other antioxidants, L-arginine is soluble in water and fat. It also works to boost other antioxidants in the body. While L-arginine may be a healthy supplement to improve general health, it is not going to boost HCG levels.

N-acetyl L-carnitine is an amino acid that works with energy production. It may help reduce symptoms of male menopause and nerve pain in diabetes patients. There is no evidence that N-acetyl L-carnitine will boost HCG. Potential side effects of taking N-acetyl L-carnitine include stomach discomfort and sleeplessness.

L-ornithine works to dispose of nitrogen during the urea cycle. We found no link to weight loss or HCG. Green tea extract is a great weight loss ingredient. There is tons of scientific literature supporting this ingredient, though none is directly linked in any of the literature we found on HCG Activator.

Saffron is a spice commonly used in cooking. Extract from the saffron plant may help reduce feelings of depression or boost mood, but there is no link to weight loss.

Black Cohosh is a natural treatment for menopause symptoms, like hot flashes. Despite being widely accepted, as an alternative to hormone replacement therapy, there is no evidence black cohosh actually stops hot flashes. Huperzine is thought to improve memory and cognitive function.

Advantages of HCG Activator

  • All ingredients for HCG Activator are listed online.

Disadvantages of HCG Activator

  • None of the ingredients will boost HCG levels.
  • Clinical references are not linked to published studies.


It is likely that any weight loss as a result of taking HCG Activator is linked to the green tea and nothing more. Green tea contains caffeine, which can boost metabolism. We have no idea how much green tea is included, so we are left asking more questions than we have answers.

HCG Activator Scientific Abstracts:


Past studies clearly show that dietary l-arginine supplementation can reduce white fat mass in obese rats. The following study tests the efficacy of l-arginine within diet-induced obesity.  Concentrations of insulin, growth hormone, adiponectin, triiodothyronine, corticosterone, and thyroxine showed no difference in control rats and rats administered with l-arginine. L-arginine treatment, however, concluded with lower serum concentrations of triglycerides, glucose, leptin, glutamine, urea, and branched-chain amino acids, elevated levels of nitric oxide metabolites, as well as enhanced tolerance to glucose. Dietary arginine controls nutrient partitioning, shifting accordingly to favor muscle over fat gain and could prove useful for the improvement of metabolic profiles as well as decreasing body white fat in obese rats. [1]


Results from ANOVA pointed out that the participants who were given the arginine-ornithine mixture had much higher scores in total strength and lean body mass (p less than .05), with substantially lower urinary hydroxyproline (p less than .05) than participants taking a placebo. It was thus concluded that arginine and ornithine could quickly increase total strength and lean body mass (when taken alongside a rigorous strength training program) when taken in prescribed doses. Arginine and ornithine assist in sustained stress recovery by calming the breakdown of tissue, which has been showcased by lower urinary hydroxyproline levels. [2]

N-Acetyl L-Carnitine

The use of N-Acetyl-L-Carnitine supplement substantially improved lipid peroxide levels (−12.8%) within the blood as well as physical symptoms like “blurry eyes,” “tired eyes,” “early satiety,” “muscle pain/stiffness,” “dizziness,” “epigastralgia,” “arthralgia”, and “quickly breaking into a sweat.” Control displayed a substantially favorable rate of improvement – most of all for “dizziness.” However, participants who were ingesting the test compounds experienced substantial elevations in total cholesterol (4.5%), HbA1c (3.4%) and fasting blood sugar (4.1%). The results of the study indicate that ingestion of the N-Acetyl L-Carnitine supplement could decrease oxidative damages, but its interaction with QOL (Anti-Aging QOL Common Questionnaire) was equivocal. [3]

Green Tea Extract

There was a significant amount of weight-loss experienced from 76.8 ± 11.3 kg to 75.7 ± 11.5 kg (p = 0.025), along with a reduction in body mass index (p = 0.018)and circumference of the waist (p = 0.023) following a 12-week high-dose treatment of epigallocatechin gallate. The study showed a consistent trend of reduced total cholesterol (hitting 5.33%) and reduced LDL plasma levels. The subjects in the study showed considerable tolerance for the treatment and did not report any adverse side effects. Ghrelin levels were substantially lower, and there were high levels of adiponectin detected within the group than in the placebo group. The results of 12 weeks treatment of high-dose green tea extract showed significant weight-loss, decreased waist circumference along with a steady reduction in total cholesterol and LDL plasma levels with no side effects within the obese women subjects. High-dose green tea extract’s antibiotic mechanism could be linked in part with ghrelin secretion blockage, which led to elevated adiponectin levels. [4]

HCG Activator Side Effects:

Users have had mixed weight-loss results with HCG Activator. While many people have used this product without any problems, others claim to have experienced side effects.

Stomach Pain

Stomach pain can range from a discomfort in your abdominal area to very strong pangs. In most cases, stomach pain goes away quickly with light treatment. However, you should seek medical assistance if your stomach pain is accompanied by fever, dehydration, bloody vomit/stool, inability to keep down food for more than two days

What causes stomach pain?

Stomach pain is a symptom of many illnesses. Some of the most common causes of pain in your stomach are indigestion, constipation, food poisoning, and lactose intolerance.


Nausea is an unsettling feeling of having to vomit. Along with nausea, you may have acid reflux (bitter tasting fluids coming out of your stomach into your throat), stomach ache, bloating, and dizziness.

What causes nausea?

Nausea is sometimes brought on by simply seeing, tasting, or smelling something distasteful. In these cases, it’s unrelated to any illness. There are many conditions that might cause you to have nausea. Motion sickness, gallbladder disease, food poisoning, ulcers, and gastroparesis are known to lead to nausea. [1]


Jittering (also known as “the jitters”) is an uncontrollable mild shaking or trembling. When you have the jitters, you feel on-edge, anxious, and even nervous or paranoid.

What causes jittering?

Excessive caffeine use is a major cause of jittering. If you find yourself with the jitters, try limiting how much caffeine you consume. Check the caffeine levels of your food. Jittering also happens when you undergo a lot of stress. Problems at work or at home can lead to an unexpected case of the jitters.

Chest Pain

There are many types of chest pain, from a mild ache to the feeling of being stabbed. In many cases, the pain isn’t limited to your chest. It travels up to the shoulders, neck, jaw, and back.

What causes chest pain?

Chest pain can be related to your heart, lungs, or gastrointestinal system. If you have chest pain, it can be sign of a heart attack, gallstones, bladder inflammation, pneumonia, or viral bronchitis. [2] Because chest pain is linked to such serious conditions, it should not be ignored. If you begin to experience chest pain, seek medical attention. As with any weight-loss supplement, take note of the potential side effects and consult with a doctor before beginning use.

HCG Activator is one of hundreds of supplements that claim HCG can fight hunger so a very low calorie diet (often 500 calories or fewer) is something the dieter can stick with to lose weight. There's no scientific proof with the slightest positive result.

We focused closely on HCG Activator ingredients so we could give you the facts.


As you may be aware, amino acids are the building blocks of protein. One of them is l-arginine. It’s commonly found in foods such as fish, red meat, poultry and dairy products. Furthermore, it’s sometimes used to treat high blood pressure, chest pain, erectile dysfunction and inflammation. [1]

What is it Supposed to Do?

This amino acid [2] is sometimes found in fitness supplements and weight-loss products. It’s often claimed to increase fat loss and improve BMI (body mass index). It’s also said to improve cardiovascular health.

Clinical Research

One study was conducted by the Mayo Clinic. It revealed that, “l-arginine supplementation (3 grams 3 times daily for 12 weeks) led to reduced waist circumference and weight-loss in obese women ages 18-40 (with BMI scores of 30-40).” Therefore this amino acid may be helpful when it comes to weight reduction.


Well, l-ornithine is basically an amino acid that’s made in the body. It can also be produced in a laboratory environment. It’s sometimes used as medicine, and it’s often found in dietary supplements.

What is it Supposed to Do?

There are some claims that l-ornithine helps release growth hormones, which in turn assists with fat burning. This amino acid may also help with muscle growth. Foods like poultry, cheese, milk, eggs and fish provide l-ornithine.

Clinical Research

Some clinical research has shown that l-ornithine products can benefit the muscles. For instance, a 2010 study from Kanazawa University and Fukui University in Japan, “Proves the effectiveness of these amino acid supplements in muscle growth.” However, we are not sure if there is a real connection to weight-loss.

One that’s caught our attention is one called Leptigen. Customers are offering positive feedback and the clinically-tested ingredients have been shown to work. Want to learn more? Click above.

Best stuff ever I lost 45 lbs and kept it off 3 years later I gained 15 due to eating out but my fault. This stuff is awesome no side effects no hunger and weight really falls off.

Could you please tell us where we can purchase HCG in South Africa.


Hi! For more information on where to purchase this product, please refer to the HCG Activator official website.

Health & Beauty

Thank you for the sensible critique. Me and my neighbor were just preparing to do some research on this. We got a grab a book from our local library but I think I learned more from this post. I am very glad to see such wonderful information being shared freely out there.


Does anyone get tightness in your throat and chest pain when you take this pill?

Hi. Please make sure to consult with your physician before continuing to take this product and let them know about the side effects you were experiencing.


I am on my 2 week of LCD and have loss 12lbs. I did mess up and eat the wrong things, which caused me to stall. I’m back on track and very excited about the results 7/9/16


I lost 70lbs in a period of 6 months using HCG activator. In truth, I lost about 110lbs, but my own carelessness and lack of focus would lead me to regain some of the weight I loss during the 21 day period you must wait before starting a new regiment. Still, it’s been two years and I’m keeping it off. I first did the diet with another branded HCG product and lost 35lbs only to gain 41 immediately after finishing the diet. But I realized the diet works, and I failed. There are different stages to this diet, and if you follow them all, you can achieve quick and permanent weight loss. In my opinion the following are the two most important things to remember. 1. During the first two days you begin taking the pills, and you are aloud to eat whatever you want. It is important to forget you are dieting at this point. EAT; high fat foods. Eat burgers with fries, and supersize them if you want, but leave the soda, it’s just useless. Eat ice cream, regular, not diet ice cream. You’ll probably gain 3-5lbs in two days, and that’s a great thing. As was explained to me; at this point, the HCG is attaching itself to the fat going in and creating a map of your fat deposits so that when you drop to 500 calories a day it knows where to pull the fat from so you can burn it for energy. If you do this correctly you won’t feel weak or hungry after the first week. The first time I did the diet, I had a rough 3 weeks where I was weak, hungry, and not loosing weight. Once I did it this way, I’ve always felt great with plenty of energy and never hungry, though weak sometimes if I over exert myself. 2. The final phase is where you stop taking the pills, but continue the diet for 3 weeks. No pills, same diet, except you increase the calories daily until you reach your daily calorie limit. This was the key to keeping the weight off. After you are completely done, you can slowly add some different foods that weren’t allowed back in your diet, and keep the weight off. This is when I joined the gym, and it was worked for two years. I don’t sell this stuff. I have no interest whatsoever in what you do. But I wanted to encourage you, and let you know that you can do this!

hcg. Work lake injection


I have high blood sugar. And am useing hcg ?


I have taken HCG Activator twice and both time dropped around 12 pounds. With that being said I did not follow their weight loss program as closely as I should have. My husband did it the same time I did and he lost 19 pounds in 30 days. The low calorie meal plan was super easy to follow, on my workout days I increased my calories to around 1000 per day and that worked well for me, i felt good in my workout and I continued to lose weight. The great thing about this program is that it is easy and you can change it up to work with how active you are. My husband is in a physically demanding job and we increased his calories to 1300 per day and he felt good, good energy and he continued to lose weight.


Have tried hcg activator. Actually did see results by the second week. Waist slimmed down alot, just sad I didn’t do the maintenance. I only gained back 4 lbs from the 14 lbs I lost.


I have questions about the diet plan, but I am having trouble finding someone to ask. I called the number on the Hcg activator site and it went to a voice mail, and everyone on line just makes comments about how tey love it or hate it. I haven’t even started the program, because it is not specific enough and I want to make sure I do it correctly.


I’ve used this product in the past and got results. My struggle was with the stabilization phase(phase III). It was hard for me once I stopped taking the hCG Activator to stay off sugar and starches. So I gained some of my weight back. I think it would have been helpful to take supplements to help curb those cravings.


for the three weeks i have to wait to go back on hcg what food do i eat within thw weeks im off the cycle
