An independent review conducted by BioAlternatives Laboratories on Revivogen solution concluded a 90% DHT inhibition, which is quite amazing considering that only Dutasteride came close to that mark under other laboratory tests, and were talking about an oral drug whether Revivigen is a topical product. The study was commissioned by Advanced Skin and Hair and conducted by an independent laboratory, BIOalternatives (http://www.bioalternatives.com) that specializes on tests for pharmaceutical, nutracutical and cosmecuitcal products. "BIOalternatives is a service company offering cell-based assays to support drug and healthcare product development. With more than 10 years of experience, BIOalternatives provides customized informative biological solutions to >200 companies through 16 countries all over the world. For this test BIOalternatives has developed a novel test to quantify the effects of any compound on Testosterone metabolism in living human skin tissue (reconstructed human epidermis) . The living skin tissues are given equal doses of Testosterone which under common metabolism is converted to DHT and other androgens. The quantity of DHT produced by the test tissue is measured for the control and all compounds being tested for correlation. Each compound is tested on three dissociate tissues to ensure the tests validity. revivogen hair loss Resuming, Finasteride, when applied topically to an figurative human scalp (scientifically accepted equivilent) which had been infused in Testosterode and 5-alpha reductase, and had been allowed to eventually produce DHT .... was applied topically Finasteride, Dutasteride, and Revivogen. Finasteride, after a period of time inhibited the presence of DHT by 67%. Dutasteride, after a period of time inhibited the presence of DHT by 80% and 86% depending on dose. The compounds in Revivogen inhibited the presence of DHT by 90%. 90% DHT blocking is great news for hair loss sufferers worldwide, Revivogen passed the studies now it has to pass the public test and that's where things get tougher.
