Hi-Tech Pharmaceuticals Protropin – 150 Tablets


In stock

Hi-Tech Pharmaceuticals Protropin is formulated to help increase natural HGH production which benefits strength training, increasing in muscle mass, increasing physical endurance, recovery from exercise, and tolerance to workload.

Protropin is based on two clinical studies that are some of the first to evaluate qualitatively, the secretion of growth factors following stimulation by oral compounds. The results showed that oral administration of a combination of 1200mg of L-arginine-2-pyrrolidone-5-carboxylate +1200mg of (S)-2,6-Diaminocaproic acid provoked a release of pituitary somatotropin (a growth hormone secreted by the anterior pituitary gland) and insulin. Hi-Tech researchers found this amazing study when looking for other compounds that would benefit Hi-Tech's Cyclosome Technology on compounds that are not usually very bioavailable through oral administration. 

This study was performed at the University of Rome and determined that a combination of 1200 mg of L-arginine-2-pyrrolidone-5-carboxylate +1200mg of (S)-2,6-Diaminocaproic acid, when given orally to a group of male volunteers, was over 10 times more effective at increasing blood levels of human growth hormone than when taking only the amino acid L-Arginine by itself, yielding an average net GH increase of more than 700%. 

According to these researchers, "We could demonstrate that the association of the two amino acids does result in the release of biologically active GH able to affect peripheral cellular receptors and thus cell growth in general."


  • Increase in Muscle Mass
  • Increase in Strength
  • Increase in Physical Endurance
  • Increase in Recovery from Exercise
  • Anti-fatigue through lactic acid buffering
  • Increased tolerance to workload

The second clinical study was performed by USP Labs on PowerFull which was scientifically shown to increase HGH by 221% in one dose! It also significantly increased natural testosterone by at least 53%! This study showed a dramatic increase in the quality of sleep to aid increased recovery. Protropin greatly enhances the mind-muscle connection by increasing dopamine and can also improve athletic movements by increasing contractile strength with weight training. There are also specific triterpene steroid saponins and sapogenins from Chlorophytum Borvilianum that are adaptogens. In short, Hormonal Adaptogens like the specific alkaloids release more testosterone, less estrogen, and basically supercharge your hormonal output!

Protropin is a revolutionary breakthrough in the field of oral HGH enhancement and is the next major advancement in the growth hormone category with its foundation firmly built on the successes of those revolutionary original formulas, the Rome Study and the USP Labs study on PowerFULL. Protropin delivers all the benefits of these clinically researched HGH ingredients

Researchers at Hi-Tech recently developed a proprietary process called Cyclosome™ Technology. This one-of-a-kind technology involves entrapment of hydrophobic prohormones and other testosterone-boosting compounds with a water-soluble prohormone–cyclodextrin (CD). This complex in liposomes has been investigated as a new strategy to combine the relative advantages of CDs and liposomes into one system, namely prohormone-in-CD-in-liposome systems called Cyclosomes™. 

You can think of all this in terms of a ‘Trojan Horse,’ passing through the liver, unharmed and intact, as opposed to being destroyed in the liver like all other hormonal products on the market, past, and present. This new Cyclosome™ technology allows the Trojan Horse to deliver prohormones and testosterone boosters to your systemic circulation by the intestinal lymphatic route, circumventing first-pass inactivation in the liver for the very first time. Almost all previous oral capsules and tablets manufactured to increase testosterone, including testosterone itself, experience the "first pass effect" which renders the active compounds virtually useless.

Cyclosome™ Technology, the most advanced liposomal delivery technology ever developed for bioavailability, is the answer to poorly absorbed testosterone-boosting compounds and legal prohormones into the body so they can work! The pharmaceutical industry has embraced this cutting-edge technology in recent years and Hi-Tech Pharmaceuticals is one of the first to utilize it!
