Hi Tech Pharmaceuticals 1-Testosterone (1-Androsterone) 110mg - Muscle Builder & Strength Supplement for Bodybuilding, Workout & Athletic Performance - 60 Capsules - Boost Energy & Endurance for Gym & Fitness Training

1-Testosterone™ by Hi-Tech Pharmaceuticals is based upon a naturally occurring metabolite for many animals including man that has properties far different from standard testosterone in the body. 1-Testosterone™ is more of a mild hormone that will give you cleaner gains and dramatic strength increases. There are three prohormones to this compound:1-androstenedione, 1-androstenediol and 1-Androsterone aka 1-androstene-3b-ol-17-one. Of the three, only 1-androsterone is still available on the U.S. market, and this is what Hi-Tech manufactures using its proprietary Cyclosome™ Delivery system for increased bioavailability.
