HCG Complex Review - 19 Things You Need to Know

HCG Complex boasts that it’s an all-natural supplement that offers “quick and easy weight loss.” The company also says that the product has no side effects. Unfortunately, after a bit of digging, we found reports of headaches and dizziness, making us question the reliability of this supplement.

Additionally, the FDA stated that low-calorie diets like HCG Complex could be detrimental to health if done for extended periods, which they don’t mention on their website. To reach the bottom line, our researchers investigated the ingredients and science to see if these weight loss drops from BioSource Labs can help you achieve your weight loss goals.

HCG Complex can be purchased through their Official Site.

What is HCG Complex?

what is HCG Complex

HCG Complex is a popular organic and natural weight loss supplement used for weight loss, whose initial purpose was to aid in other health problems.

Their diet plan complements most HCG dietary supplements, and HCG Complex is not any different. These best-selling drops require you to follow a restrictive calorie diet, similar to the standard HCG diet.

HCG Complex is developed by the respected dietary supplement company BioSource Labs, LLC.

All products manufactured by this company are produced in compliance with FDA rules and guidelines and GMP standards.

This formula is 100% natural, as it is derived from primary human chorionic gonadotropin hormone supplementation. The company claims that this supplement is safe to use by anyone looking to lose weight naturally and healthily.

Company Info

How Did HCG Complex Start?

HCG Complex is a dietary supplement produced and distributed locally in the U.S. by a company called BioSource Labs.

The company was established in 2010, and since then, it has maintained an upward trajectory. It has been building a reputation for superb products with even better results.

HCG Complex was developed due to the original HCG dietary method discovered in the 1950s by Dr. A.T.W. Simeons, a British endocrinologist.

In its early years, Dr. Simeons extracted the hormone from pregnant women to inject it into teenage boys. The result he was trying to accomplish was to help adolescent boys with low levels of testosterone.

However, somewhere along the way, he noticed something quite interesting. Not only that, he managed to bring their testosterone levels back to normal, but he also caused them to lose weight at an unprecedented pace.

Although HCG Complex is not sold through an MLM program, the product offers an affiliate program.

What Is It?

What Is Human Chorionic Gonadotropin?

HCG stands for Human Chorionic Gonadotropin, a naturally found hormone in the human body.

Pregnant women produce it to facilitate the breakdown of fat that helps nourish the fetus.

Dr. Simeons theorized that HCG could help the breakdown of stubborn fat in individuals who were not pregnant.

After the product underwent additional research, he became certain about the weight loss power that HCG possessed. As time went by, his theory and formula have been perfected to create many of the nutraceutical technologies today.


HCG Complex Claims

hcg complex claims

As the company claims, HCG Complex works to help your body naturally unlock excess fat.

However, while taking the drops, you also have to follow a strict diet regime. The diet proposes a limitation of 500 calories a day, in whole foods, excluding the first few days.

The company guarantees great weight loss results, with as much as 1-4 pounds down the drain a day. If you are not satisfied with the results after 30 days, the company promises to give you your money back.

While taking the drops, you are not required to exercise to get the results that are promised.

The company also adds that the drops are easy to use daily, as well as very affordable.


HCG Complex Ingredients

The company advertises this product as the perfect combination of more than 25 ingredients. This formula works to tame your hunger and burn fat by activating your body’s physiological production of hormones.

Some of the most important ingredients in this product include:


Ginseng is a potent ingredient that enhances energy production and improves the overall health of the consumer.

While not all of these health benefits are proven scientifically, many of them are, and it is completely safe to use it as a supplement.


According to The Journal of Nutrition, this ingredient boosts energy production through enhanced metabolism, thus helping to keep body weight and fats in check. Studies show promising results in dietary arginine, promoting muscle gain over fat.

This way, it has been proven to reduce levels of white fat in both genetically and diet-caused obese rats.


L-Carnitine is an amino acid that plays a role in energy production. It transports fatty acid chains to the mitochondria for oxidation, thus keeping body weight in check.

However, it’s important to mention that only some studies prove this correlation. According to Obesity Reviews, most studies appear to show the contrary – that there are no clear links between L-Carnitine and weight loss.


According to Nutrition Research (NY), this component stimulates the breakdown of fats, thus reducing their storage or accumulation in the body.

The most direct way it does this is by improving fat metabolism during exercise, especially endurance exercise. This way it lets athletes postpone fatigue and burn more calories during their workout.


L-Lysine is an amino acid that helps to reduce fatigue, enhance energy production and appetite suppression, thus helping in weight management.

Lysine is important for the metabolism of carnitine and in that way it is indirectly involved in the process of weight loss. However, it is undoubtedly important in the process of fat metabolism.

Glutamic Acid

According to the European Journal of Clinical Nutrition, Glutamic Acid helps in energy production, thus assisting in fats oxidation and weight loss.

Studies show that women who took glutamine for four weeks experienced weight loss even without substantial changes in diet, or exercise regime.

Update July 2019: The ingredients now listed on the HCG Complex (Complex Diet Drops) label are:

  • Amino Acids
  • Chromium Picolinate
  • Monoammonium Glycyrrhizinate
  • GABA
  • Raspberry Ketones
  • African Mango Extract
  • Coleus Forskohlii Root
  • Green Tea Extract

Does It Work?

Does HCG Complex Work?

does hcg complex work

The company claims that the product’s ingredients are natural, and that is true.

However, if you refer to the research we provided about the ingredients, there isn’t a definite connection between them and weight loss. Therefore, you should do additional research before deciding to break the bank and buy HCG Complex, as it is not that cheap.

One thing that should be noted is that the product does come with a money-back guarantee if you are not satisfied with the results.

Something that concerns us and stops us from claiming the product’s efficiency is the various reviews online. Some claim that the product works; others bash it and vigorously disapprove of using it.

Many reviews mention numerous side effects that can appear after using the HCG Complex for an extended period.

A catch that comes with weight loss is that users have to stick to a strict diet. The diet is supposed to maintain a caloric deficit throughout the intake of the drops. Therefore, if you do not follow the diet propositions, there is a slim chance that you will lose weight.

The HCG Diet proposes a daily caloric intake of 500, 800, or 1200 calories. Any of the three causes a big caloric deficit, so if you follow that regime, you are almost certain to lose substantial weight with or without the drops.

Due to the possible side effects of both the product and the diet, it might not be worth it — there healthier and more natural ways to lose weight quickly.

Does It Work The Same For Everyone?

Does HCG Complex Work the Same for Everyone?

The results can be different for different people – for some, it works better; for others, it does not.

Many reviews state that the beginning of the diet and the drops burn fat at a rate of 1-4 pounds a day. However, after a while, that weight loss slows down and eventually even stops for some users.

Also, many report low energy levels because of the intense weight loss and the minimal diet. Some people do not have sufficient energy to get them through their daily activities.

At the end of the diet, many users experience a reversal in weight and quickly put most of the weight back.

According to Psychosomatic Medicine, there is a claim that this happens because of the low-calorie diet, which slows down your metabolism and increases cortisol levels, which leads to weight gain, as some studies show.

Details on HCG Complex and Weight Loss

hcg complex weight loss

Doctors claim that HCG, the main product’s ingredient, does not cause you to lose weight, but it changes your metabolism and the way you lose weight.

HCG is a hormone that is present in all individuals, both men and women. When women get pregnant, it is secreted in high amounts to let the body know that it is pregnant.

On top of that, it stimulates the secretion of other hormones in the body as well. After that chain reaction is caused, they together affect the body’s metabolism, digestion, muscles, and more.

According to the company and some doctors, HCG stimulates certain follicles on glands that in turn help the body to maintain muscle tissue. They add that when someone does a very low-calorie diet without using any medication, it becomes a “crash diet.”

This means that your body starts losing muscle. Since muscle is much heavier than fat, the numbers on the scale go down very quickly.

A “rebound” effect appears when the diet is over, and you gain all of your weight back and sometimes more.

So, even though ambassadors of the HCG diet state that the weight loss results from a fat loss only and not muscle loss, there are no scientific studies available out there to support these claims.


HCG Complex Pros

HCG Complex has undergone many reviews, and there is some data regarding the most prominent advantages of the product. Some of these advantages include:

  • Free exercise program
  • No known serious side-effects
  • HCG Complex is one of the most affordable HCG drops on the market
  • Bulk discount option available
  • Full 30-day money-back guarantee if you are not satisfied
  • A long list of all-natural ingredients and amino acids
  • HCG Complex is NOT a prescription drug, so there is no need to visit a doctor’s office

HCG Complex Cons

Even though there are many positive reviews and testimonials of the product, the HCG Complex still does not have clinical information to support its claims. Some negative reports of the product include:

  • HCG Complex is not scientifically proven to help in weight loss
  • Exercise might be required to achieve the desired results
  • The quantity of the ingredients is not listed on the box

How to Take HCG Complex?

hcg complex directions

Following the supplements, instruction is a crucial aspect of taking HCG Complex.

First, the drops should be kept in the refrigerator to keep them fresh. It would be best if you did not drink or eat anything at least 15-30 minutes before or after use.

The intake is simple; you place them under the tongue and wait for them to dissolve.

The process is split into four main phases.

Phase One – Start Taking the Drops & Binge Days

During the first phase, you should take the drops three times a day. The first time should be before breakfast, the second before lunch, and the third should be taken before dinner.

Ten drops should be placed under the tongue and held there for two minutes. On the first day, you are allowed to eat many fats to store energy for the future period.

Phase Two – Start the Low-Calorie Diet

The second phase begins on the third day. At this time, you start your low-calorie diet. You have to avoid sweets and fats, as well as starches and carbs.

You stop using HCG Complex drops after three or six weeks.

Phase Three – Stabilization

The third phase begins when you stop taking the drops. Now you can slowly increase the calorie intake.

However, do it slowly and eat clean.

Phase Four – Maintenance

The fourth phase, the final one, is the end of the diet plan.

If you have reached your desired weight loss, you can stop the diet and the consumption of drops. However, do not get too carried away. You still have to eat healthily and watch the number of calories you eat.

What is the HCG Diet?

What is the HCG Diet?

The HCG Diet is a low-fat and very low-calorie diet. The three types of HCG Diets are 500 calories, 800 calories, and a 1200 calorie diet. It goes along with taking the HCG Complex drops, and it is split into three main phases.

  • Loading Phase: In this phase, you can eat a lot of high-fat and high-calorie foods for the first two days.
  • Weight Loss Phase: In this phase, you continue taking HCG Complex drops and eat a set number of calories per day for 3-6 weeks.
  • Maintenance Phase: In this phase, you stop taking HCG and slowly increase food intake, but stay away from sugar and starch for the next three weeks.

Those who have less weight to lose can do the diet for three weeks. Others, who want to lose more, can do it for six weeks and repeat the process until they get the results.

During the weight loss phase, you are allowed only two meals per day. These should contain lean protein, vegetables, some whole-grain bread, and fruit. Butter, sugar, and oils should be avoided, but you should drink plenty of water. You also do not have to abstain from mineral water, tea, and coffee.

Side Effects

Potential HCG Complex Side Effects

hcg complex Side Effects

The side effects mostly depend on the type of HCG you are taking. The prescription form of HCG is the one that is likely to cause negative side effects.

Other types, like the homeopathic HCG drops, are not so severe on the body.

However, the HCG diet that has to accompany the drops is a big stress to your organism. It is a big change from your regular diet, so this very low-calorie intake might have some adverse effects.

Some possible side effects that might occur due to the diet and the HCG Complex drops are:

  • Constipation
  • Headache
  • Dizziness
  • Leg Cramps
  • Rash
  • Hair Thinning

On top of that, the FDA reports that very-low-calorie diets can cause electrolyte imbalance.

The side effects mentioned here do not occur often, and they can usually be prevented or treated with common medications.

Nonetheless, they still do occur in a small portion of HCG users, so it is something to think about before you start using this product.

Product Warnings

HCG Complex Product Warnings

One thing to consider is that even though the HCG Complex is a well-known product, many medical professionals are not suggesting its use for weight loss.

This is because it is not straight-forward because it is unsafe. There is not enough research to prove that it is an efficient way of losing weight.

Moreover, the possible side effects that we have mentioned above are also a point that is making professionals doubt whether the product is worth it.


Any HCG Complex Lawsuits?

hcg complex lawsuits

There are no known HCG Complex lawsuits. However, the FDA has issued several warnings against and sent letters to different HCG product manufacturers, warning them that they are selling HCG weight-loss drugs that are not approved for such purposes.


HCG Complex Alternatives

There are many possible alternatives to HCG Complex that can be found on the market.

We have compiled a list of 5 best alternatives. These are all marketed as hormone-free and natural products. On top of that, all of them come in the form of drops or pills, so there are no injections included.

These alternatives include:

  • LDD (Liquid Diet Drops)
  • HCG Activator
  • Low Dose Naltrexone
  • Nutra Pure HCG
  • Glucomannan
What Users Are Saying

What Users Are Saying

“Product is working great. I have dropped 9.5 pounds in the 7 days I have been on Phase 2. As long as you can stick to the recommended amount of food, this product works as promised.”

“The 500 calorie diet suggested to go with this is a bit of joke because anyone who’s only eating 500 calories doesn’t need drops to lose weight. But I’m taking the drops as instructed and I guess we’ll see.”

“The product didn’t work for me – I saw zero results and I thoroughly searched this product and compared it to others.”

Bottom Line

The Bottom Line on HCG Complex

You may want to take a moment before ordering HCG Complex. Well, we like that it comes with a guarantee and that it contains a few natural ingredients. We’re skeptical about this one because there’s no connection between the ingredients and weight-loss. Also, we’re concerned because customers comment about HCG Complex not working and being the cause of negative side effects.

If you want to lose those extra pounds, you shouldn’t settle for side effects like with this hormonal health supplement. That’s why we suggest going with a complete weight-loss system that can help you achieve healthy lifestyle changes.

Noom is one of the best weight-loss programs we have ever seen, as it provides individual coaching, an extensive food database created by top scientists, interactive support groups, personalized meal plans, and more. Plus, its beneficial effects have been published in journals like Scientific Reports.

7 HCG Complex Reviews

  • This absolutely works!!! Check out my story
    Rhys Oliver (Verified Purchase)

    This product works for sure. I started the diet April 17th of this year at 211 lbs and it’s now May 1st and I am at 191.4 lbs. I have lost a total of 20 pounds… I’m doing the 800 calorie diet and have added light cardio in the mix… I already look like a different person. The diet actually makes u loose inches as well as pounds so if u stall just know the inches are melting off. You will notice your clothes hanging off you each day. You literally shrink to what you are beneath the weight daily. The drops curve your appetite tremendously and as the weight comes off you feel a lot of energy. I would definitely recommend this to anyone looking to lose weight. It may seem hard at first but once you see the pounds and inches dropping from all parts of your body, stomach, stomach sides, chest, face, legs, neck, arms etc., you will be motivated to continue for sure and gets easier. Lol you can do it!!!!!

  • Not the REAL HCG
    Maria (Verified Purchase)

    Gives you a headache and does not contain any HCG in it! It’s not the real HCG and dies not work the same….

    • Rhys Oliver

      It works ms lady… you must have not done it right I didn’t get headaches

  • It worked for me!
    Devonne Gardner (Verified Purchase)

    I lost 40+ lbs in the 43 day plan. I didn’t have any side effects. It really made me think about & look at what I was ingesting. I now prefer fresh foods without preservatives. Anything heavy in fats gives me a stomachache. If I overeat on breads, pasta, or potatoes I feel bloated for 6-8 hours. I have not taken drops in 60 days and my good nutritional habits remain. Still drink black coffee, no soda lots of water, smaller portions lots of veggies. My blood pressure is lowest it’s been in years, my A1C is great and I’m no longer anemic.

  • diana Hernansdez (Verified Purchase)

    the first two days are binging days so I can eat what I want then the 3rd day is when I start the 500 calorie diet is that correct? I also need some type of diet plan or meal recipes where can I get this information? I just started these drops yesterday.
