The results of my research into HCG drops were quite surprising, so we wrote an in-depth review, examining the side effects, ingredients, clinical studies and customer care. We also focused on dozens of user reviews and responses posted online. Lastly, we condensed all of the facts to give you the information you need.
What are HCG Drops?
To start, HCG drops are prescribed to women for fertility purposes.  Several companies also market it as a weight-loss aid. Ingredients include human chorionic gonadotropin, vitamins and minerals. Over-the-counter supplements don’t contain the actual hormone because it’s illegal.  The suggested use is to dispense the liquid under the tongue. You’re expected to follow a 500 calorie per day diet while using this product. 
HCG drops were initially used as a homeopathic treatment for weight-loss around 2010. Multiple online retailers sell the supplement. We found dieter feedback posted online and some products contain natural ingredients, but read on…
Diet Restrictions – “Too Much?”
The first issue we felt needed to be addressed with HCG drops were the strict guidelines. According to our Research Editor, “Most HCG drops are used in conjunction with a 500-calorie per day diet plan. This restriction is not realistic, nor is it healthy. Most physicians do not recommend less than 800.” 
”500 calories a day is starvation, plain and simple. The weight loss on this program is not from the HCG, but from the caloric deprivation,” said one dieter.
Another customer claims, “You can consume 500 calories and lose the weight without spending $200 on drops, but I think only taking in 500 calories a day can be dangerous.” 
Not everyone thought the restriction was over the top. As one dieter said, “I never felt hungry on the diet.”
Another credits the supplement with preventing hunger, “HCG cuts the cravings so you can stick with the 500 calories to lose the weight.”
HCG Drops Side Effects – “Concerning?”
After reading all sorts of customer feedback on HCG drops ingredients, it’s clear that plenty of dieters have experienced nasty side effects. One user said, “Made me sick. Don’t buy.” 
According to another dieter who suffered HCG drops side effects, “I used this product for a few days, and it caused my heart rate to increase. I will never use this again.”
These types of reactions were not shared by all users. One user shared, “I never was tired or weak, nor did I have horrible side effects.”
Another said, “Good results with no side effects.” 
Our research has proven that if a particular aspect of a supplement or program is really problematic (dangerous side effects, high price, lots of diet restrictions) the likelihood of weight-loss success for the long term is minimal. If HCG drops really do cause bad reactions in a lot of people, this could be a major issue.
The Science – “Is it Validated?”
While there is some clinical research that supports HCG drops for fertility purposes, there is no scientific data to support this one as a weight-loss aid. There’s also the issue that the US government, including the FTC, has called it a fad.  In fact, these supplements don’t actually contain human chorionic gonadotropin. Rather, they contain vitamins and minerals. If you lose weight, it’s probably from severe calorie restriction at just 500 calories per day. At DietSpotlight, the clinical validity is a huge part of the review process. If there are no facts, the dieter might as well turn the other way. 
The Bottom Line – Do HCG Drops Work?
Alright, do you need to rush off to the store to find this one? Well, we like that HCG Drops may contain natural ingredients and that it’s readily available. We’re just concerned that there’s no research showing the connection to weight-loss. Furthermore, some people have reported negative side effects and the food restrictions may be too intense. 
If you’re ready to lose weight more quickly, we suggest trying a weight-loss supplement that contains a proven proprietary blend and does not cause any harsh side effects or require any severe dietary restrictions.
Among the best products we’ve seen this year is one called Leptigen. This supplement contains a proprietary combination of four ingredients, which have been shown in documented scientific research to boost metabolism and encourage fat loss. Moreover, we can’t locate any negative feedback about harmful adverse effects and dieter reviews found on the web reveal people are seeing good results.
Also, the company that makes Leptigen is so confident in the product that they’re offering a Special Trial Offer, which is a positive sign.
Previous HCG Drops Review (Updated June 6, 2014):
What You Should Know about HCG DropsHCG Drop is a homeopathic approach to weight loss that makes use of the HCG hormone. The HCG hormone is commonly used for fertility, and is not approved by the FDA for weight loss. Evidently it is very versitile; it comes in an HCG Spray and even HCG Solution Mini Tabs.The idea behind it is a simple drop on the tongue, combined with a very low calorie diet will help you lose up to 30 pounds in 30 days.
List Of HCG Drops IngredientsHCG Drop contains one active ingredient: the HCG hormone.
Product FeaturesHCG Drop is a simple drop you place on your tongue, comprised of the HCG hormone. This hormone is a bit different than say the human growth hormone found in Growth Factor 9. It can also be found in shakes, and other products. It claims to be scientifically proven to help with weight loss, yet we cannot find any information to support it; and we know it is not FDA approved for weight loss. We believe that because of the suggested very low calorie diet restriction of no more than 500 calories per day is what causes the weight loss and more even fat distribution, claimed to be the drastic weight loss results from the HCG.
Advantages of HCG Drops
- HCG Drop is just a drop you put on your tongue.
Disadvantages of HCG Drops
- HCG is not approved by the FDA for weight loss.
- HCG is commonly used for fertility and boosting testosterone levels in males.
- HCG may cause side effects including: water retention, headaches, restlessness, tenderness of breast tissue, depression, irritability. There are some rare, but potentially serious side effects including: ovarian hyperstimulation. Symptoms include: abdominal pain and swelling, vomiting, nausea, diarrhea, infrequent urination, weight gain, and swelling of the legs and feet. More on this topic on HCG Drops Side Effects.
- This diet makes use of an extremely low calorie diet, of only 500 calories per day. This is starvation and will backfire, slowing the metabolism.
ConclusionHCG Drop is unhealthy. Even the FDA has concerns about its legality. Similarly Jadera contained illegal prescription medications as defined by the FDA. How a small amount of this hormone combined with a drastically reduced calorie intake will help increase energy levels and boost the metabolism is beyond us. Eating 500 calories a day will certainly help you lose weight, but it will also leave you feeling bad, and will send your body into starvation mode, where the metabolism will slow and hold on to everything you put in it, eventually causing weight gain when you resume eating normal calories. Just as well as other drops, HCG Drops and Activ8 X have dodgy side effects. We do not recommend this product, at all. Instead, find a proven weight loss supplement that contains a fat burner or an appetite suppressant, and combine it with a healthy diet and exercise routine, while drinking more water. This will bring you far more success than the HCG Drop will.

HCG Drops Scientific Abstracts:
Serum administered at the start (14.1 nmol/liter) was 1.2% of intratesticular testosterone (1174 nmol/liter). FSH, as well as LH, were significantly suppressed to 5% and 3% respectively, and intratesticular testosterone had been contained by 94 %( 1234 to 72 nmol/liter) in the placebo/ T enanthate group. Intratesticular testosterone had risen linearly with a higher dose of hCG (P < 0.001). Post-treatment intratesticular testosterone was less than baseline (25%) in the 125 IU human chorionic gonadotropin participants, which was 7% less than baseline in the 250 IU human chorionic gonadotropin group. The results had shown a moderately low dose of human chorionic gonadotropin would maintain intratesticular testosterone within standard parameters in healthy men with gonadotropin suppression. 
In pregnancy, hCG is virtually always noticed in serum and urine during 16 days following ovulation. Continued hCG testing is necessary for the assessing of possible ectopic pregnancy. Human chorionic gonadotropin studies change in their analytical data, and some tests may be less analytically sensitive than previous stated. Although hCG tests are trustworthy diagnostic examples for pregnancy assessments, a clear grasp of the limitations and data is necessary for real and appropriate results. 
A meta-analysis was carried out to determine if there were scientific grounds for the use of hCG (human chorionic gonadotropin) for therapeutic purposes in the treatment of obesity. Studies relating to 8 controlled trials and 16 trials which were not uncontrolled which measured the effect hCG in therapeutic treatments of obesity were tracked down and researched. The tests were ranked in the quality of methods as well as key findings, authors, and data analysis and presentation regarding weight-loss, hunger, fat redistribution, and feelings of well-being. The methodological scores had varied from 16 to 73 points with a maximum of 100 possible points. This would indicate that most of the trials were of poor methodological outcomes. One report stated hCG as a use adjunct, scoring over 50 points. All of the studies scoring over 50 points were controlled studies. In conclusion, there is no scientific evidence that human chorionic gonadotropin is useful in treating obesity. It doesn’t reduce hunger or trigger any feelings of well-being. 
Twenty participants are of twenty-five in the hCG (human chorionic gonadotropin) group and twenty-one of twenty-six participants in the placebo group had experienced 28 injections. In turn, no significant differences between the means in either group were found (injections received, weight-loss, weight-loss percentage, waist circumference, weight-loss per injections, or hunger). Human chorionic gonadotropin doesn’t seem to increase the effectiveness of an intensely proposed regimen for weight reduction.
