Without testosterone we would not have the host of anabolic androgenic steroids we have today, as most anabolic androgenic steroids owe their existence to testosterone. While many anabolic steroids are derived from the testosterone hormone there isn’t one that is more important and generally well-tolerated. Testosterone is available in two forms, methyltestosterone, testosterone chlorodehydromethyltestosterone, testosterone cypionate, testosterone enanthate, testosterone propionate, testosterone undecanoate, testosterone mix and testosterone suspension.
