Arcas Nutrition
is a pharmaceutical company specializing in the production of quality Prohormones.

Prohormones were introduced into the world of supplements in 1996 by the famous American chemist Patrick Arnold who developed the supplement androstenedione and launched it on an unsuspecting public. Androstenedione created a buzz in the world of sports and is still strongly tied to baseball icons like Mark McGwire whose use of this supplement was revealed while he was chasing the baseball record in 1998. By breaking the record this That year, McGwire brought notoriety to both baseball and the attention of legislators in the United States. Androstenedione was soon followed by a number of other supplements such as androstenediol, norandrostenediol, 1-4-androstenedione and 5-alpha androstenediol.

All have had different effects, some being converted to testosterone in the body, while others have been converted into anabolic hormones such as nandrolone, boldenone and dihydrotestosterone (DHT). After a while, Patrick Arnold’s Ergopharm company introduced prohormone 1-AD, which turned into a hormone called 1-testosterone. This was the first prohormone considered to have an efficacy comparable to illegal steroids such as Winstrol or Primobolan.
