Hi-Tech Pharmaceuticals 1-Testosterone is a prohormone supplement based on a naturally occurring metabolite that has significantly different properties compared to standard testosterone. This supplement promotes cleaner, leaner gains and notable strength increases without the common side effects associated with estrogen activity. Due to its mild hormone nature, 1-Testosterone is known for delivering sustainable gains that enhance muscle definition and vascularity.

Molecular Structure: 1-Testosterone differs from regular testosterone by the placement of a double bond within its structure. Specifically, it features a 1,2-double bond on its A ring, as opposed to the 4,5-double bond found in ordinary testosterone. This alteration prevents conversion to estrogen via aromatase and to DHT, making it a stable molecule that resists conventional metabolic pathways. A 2006 study highlighted its high androgenic and anabolic potency, with an anabolic to androgenic ratio of 200/100, superior to that of testosterone.

Usage and Effects: 1-Testosterone is effectively utilized for both cutting and bulking phases. It enhances muscle hardness and increases strength remarkably. Users often report a hardening effect and an increase in vascularity while using this product. The androgenic side effects are considerably lower in comparison to other steroids, such as testosterone.

Composition: 1-Testosterone contains the orally active prohormone 1-androstene-3b-ol-17-one, which converts to 1-testosterone in a two-step process.

Recommendations for Use: For optimal results, it is recommended to stack 1-Testosterone with a "wet" compound such as 4-andro to potentiate gains and enhance cycle benefits. This approach addresses the lack of estrogenic activity which can accompany the use of 1-Testosterone alone.
