Humanotropin by Supreme Sports Enhancements Review – What Is It and How Exactly It Works?

What Is Humanotropin?

Humanotropin is an all-natural, non-synthetic supplement made of testosterone boosters and proteins that work to increase an individual’s strength and healing. It is made of two active ingredients, the first being a proprietary bland of growth proteins called Humanofort, and the second being Ornithine Alpha-Ketoglutarate (OKG), which boosts protein synthesis. Combined, these two ingredients work to help athletes increase their lean muscle mass, shed fat, recover quicker, and work out harder and more frequently.

The Humanotropin supplement is designed and intended primarily for bodybuilders and other serious athletes, but it can be used by any adult who is in good health, although it should be avoided by people with diabetes. For maximum results, users are instructed to take two capsules of the supplement twice a day, once in the morning and once before going to bed, preferably on any empty stomach. Since it is an all-natural formula, and its testosterone boosters take time to build up, users should not expect to see the effects right away, but should continue to take the supplement for at least 6 weeks before judging its effectiveness.

According to testimonials made by past some users, regular use of Humanotropin leads to a number of positive changes, especially when paired with exercise. Some users report a decrease in healing time, which leads to more frequent workouts with better results, and an increase in overall strength. Others also report losing fat and gaining muscle more easily, especially with long-term use.



The manufacturer of Humanotropin is Supreme Science Enhancements, which is known for its Performance Series, Pharma Series, and Stacks of supplements for bodybuilders. The founder and current CEO is Ross Erstling, who also owns Herbal Innovations, another supplement manufacturer and distributor with similar products focused on fitness. Supreme Science Enhancements was founded in 2007 and its headquarters are located in Jersey City, New Jersey, in the United States of America.

Information about Supreme Science Enhancements can also be found through their multiple, active social media accounts, which allow them to offer special deals and to communicate easily with customers. They can be found on Facebook, Twitter, and Instagram, where they have over 3,000 followers, and where their special hashtag, #supremebeings, has over 6,000 tags. Supreme Science Enhancements also sells athletic wear and other workout apparel, so customers can sport the brand while they are working out at the gym or just showing off their fitness results.

Supreme Science Enhancements also has an Affiliate Program available for professionals or other athletes with websites who would like to promote the brand. Customers who have had especially positive experiences with the supplements are also invited to become a Supreme Science Enhancements Ambassador by applying for a sponsorship through the website. Currently, they sponsor a number of professional and amateur bodybuilders and other athletes who use their products and exemplify the goals of the supplements, including IFBB professional Lloyd Dollar, National Physique Committee (NPC) Figure Competitor Crystal Martin, and NPC Competitor Theresa Thompson.


How Humanotropin Works?

The proprietary ingredients of Humanotropin work together to safely improve users’ strength, stamina, and recovery time by supporting growth proteins and increasing anabolic activity. According to the manufacturer, its ingredients, including testosterone boosters and amino acids, work to give users an increase in lean muscle mass and aid in overall fat loss. The main ingredient, the proprietary Humanofort formula, works by using clusters of low-molecular weight oligopeptides that pass onto the appropriate receptor by pinocytosis. The other key ingredient, Ornithine alpha-ketoglutarate (OKG) reportedly works by increasing protein synthesis, decreasing protein catabolism, and increasing the uptake of amino acids and glucose to the muscle cells. These two testosterone boosters and growth supporters work in conjunction with each other, magnifying the effects of each.

This supplement is manufactured by Supreme Science Enhancements as part of its Pharma Line of supplements, which work to naturally affect hormone levels by stimulating biological actions. It can be used alone, or stacked with one or more other supplements for an increased effect. Supreme Science Enhancements offers it as part of a Hormone Optimizer Stack, along with their Androgenix supplement, or as part of their Supreme Stack, with both Androgenix and Omnibolic supplements.


Ingredients of Humanotropin

There are two main active ingredients that work together in the Humanotropin supplement, a proprietary blend called Humanofort and a renowned anabolic amino acid called Ornithine Alpha-Ketoglutarate, or OKG for short. The inactive ingredients include gelatin, which may be a problem for vegans or athletes who follow a kosher diet, Titanium Dioxide, a white pigment, and FD&C Blue #1, an organic compound that is used to dye foods. The Humanotropin label clearly and honestly lists these ingredients and their quantities, and all ingredients used in this supplement have been determined to be safe, healthful, and efficacious by the federal Food and Drug Administration.

The powerful proprietary blend called Humanofort is a protein peptide matrix that includes a blend of all-natural, testosterone-boosting growth factor supporters. Since it is a proprietary blend, it is impossible to know the specific quantities of these ingredients, but the label does spell out the names of the growth proteins that have been used. Added to these growth proteins are Thymosin Domain Peptides and Follistatin to promote muscle growth and cell regeneration.

The other key ingredient is 500 milligrams of OKG, or Ornithine Alpha-Ketoglutarate, which is an amino acid that works to promote faster healing times and encourage protein synthesis, leading to greater muscle gain. Specifically, Ornithine alpha-ketoglutarate is a combination of two powerful amino acids, the first being L-Ornithine, which is used to promote athletic performance, and Alpha-ketoglutarate,which stimulates the production of biological energy through the mechanism of the Krebs cycle. OKG works by increasing natural levels of glutamine and arginine, which allows an athlete’s body to boost testosterone le and decrease recovery times, allowing for more workouts.



The greatest advantage of Humanotropin is that it is made of all-natural, non-toxic, non-synthetic ingredients, which work to boost natural testosterone levels through biological mechanisms. Although the Humanofort formula is proprietary, the manufacturer assures customers that its ingredients are “100% natural and completely non-toxic,” with no risk to professional bodybuilders and other athletes. In other words, athletes and bodybuilders can take the product without fear illegal or unhealthy ingredients. Because it is all-natural, it also can be combined with other supplements without risk of contraindication or negative interaction. For this reason, many bodybuilders will use this supplement in a stack with other supplements, whether those recommended by Supreme Science Enhancers or with something else entirely.

Another advantage of this supplement is that it reportedly leads to a number of positive effects over the long term, including strength and stamina, rather than just giving a short-term, temporary boost. While it is true that users need to take the supplement for up to 6 weeks before seeing full results, the testosterone boosters then go to work in many ways. Users report an increase in energy as well as improvement in sleep and recovery times, as well as a gradual increase in strength. They also report generalized fat loss and muscle gain, leading to an improvement in overall physical health.



The manufacturer’s of Humanotropin have not submitted themselves to any certification by professional groups or third-party verification, but this is not necessarily a sign of lower quality or dependability. Instead, Supreme Science Enhancements made be too concerned with protecting the privacy and trademarked status of their proprietary blend, Humanofort. Since this proprietary blend is exclusive to products made by Supreme Science Enhancements, it’s in their best interest to keep the specific ingredients covered by trademark and protected from scrutiny. However, as a manufacturer whose facilities are located in the U.S., Supreme Science Enhancements is under the auspices of the Food and Drug Administration (FDA). This federal agency assures that all nutritional supplements are produced in a safe, healthful manner, with ingredients that are legitimate and sound.

Instead of professional certification, Supreme Science Enhancements relies on its Sponsored Athletes and ambassadors to act as proof of its quality and value. This group includes professional bodybuilders who have participated in the International Federation of Bodybuilders and National Physique Committee, as well as amateur bodybuilders, athletes, and individuals looking for personal improvement. Customers who are happy with Humanotropin also praise it on the Supreme Science Enhancement Facebook page, Twitter account, and Instagram account. Finally, across the internet, on forums, blogs, and YouTube, users have left reviews of their experiences with Humanotropin, which customers can evaluate before buying.

According to the Supreme Sports Enhancements website, a single bottle of Humanotropin costs $54.99. One bottle contains 120 capsules, with a recommended serving size of two capsules taken twice daily, so that price would cover a 30-day or approximately one-month supply of the supplement. That works out to a cost of $1.82 per day to regularly use this supplement as recommended. The cost of shipping one bottle, by FedEx, is eight dollars. The total price of having one bottle of this products shipped is, therefore, $62.99.

However, since the full effects of this product may not been seen until after six weeks of regular use, customers may need to purchase more than one bottle before accurately judging its effectiveness. Two bottles of this supplement, which would cover a two-month supply, costs $109.99, and the cost of the shipping remains $8, which would make the total $117.98.. Shipping is free, however, for all orders over $199, which means customers would get free shipping if they ordered four bottles or more of this supplement, or purchased other supplements from the Supreme Science Enhancements website at the same time. However, customers should be confident in their order and review the seller’s return policies, which do not include a money-back guarantee for any returned items.
