What is 1-Testosterone (DHB, dihydroboldenone)?
A synthetic steroid, chemically a 5α-reduced boldenone with a double bond at position 1. It activates the androgen receptor directly without needing to be converted first.
How well studied is 1-Testosterone (DHB, dihydroboldenone)?
No clinical studies in humans. Animal data (2006) show high anabolic and androgenic potency comparable to testosterone propionate, including growth of the prostate and seminal vesicles and an increase in liver weight.
What side effects and risks does 1-Testosterone (DHB, dihydroboldenone) have?
Typical anabolic steroid risks: suppression of the body's own testosterone production up to testicular atrophy and infertility, unfavourable blood lipids (HDL drops), high blood pressure and cardiac strain, acne, hair loss, psychological changes. Animal data also point to liver strain; long-term human data are lacking.
Is 1-Testosterone (DHB, dihydroboldenone) approved in Germany?
In short: no. Not approved as a medicine anywhere; controlled as an anabolic steroid in the US since 2005 (Schedule III). WADA: S1.1, listed by name, prohibited at all times. In Germany, anabolic agents fall under the Anti-Doping Act (AntiDopG): manufacturing, trafficking and placing on the market are criminal offences, as are acquiring and possessing non-small quantities for doping; for elite athletes, self-doping is a criminal offence. Black-market products are often mislabelled or contaminated.
