TRENBO A 100 is a steroid used by veterinarians on livestock to increase muscle growth and appetite. To increase its effective half-life, trenbolone is not used in an unrefined form, but is rather administered as trenbolone acetate. TRENBO A 100 is similar to the highly popular steroid Nandrolone, in that they are both 19-nor steroids, meaning that a testosterone molecule has been altered at the 19th position to give us a new compound. Unlike nandrolone however trenbolone is an excellent mass and hardening drug with the majority of gains being muscle fiber, with minimal water retention.
TRENBO A 100 chemical structure makes it resistant to the aromatize enzyme (conversion to estrogen) thus absolutely no percentage of trenbolone will convert to estrogen. TRENBO A 100 administration would not promote estrogenic side effects such as breast tissue growth in men (gynecomastia, bitch tits) accelerated fat gain, decline in fat break down and water retention. TRENBO A 100 is also resistant to the 5- alpha-reductase enzyme, this enzyme reduces some steroid hormones into a more androgenic form, in trenbolones case however this does not matter, trenbolone boasts an androgenic ratio of 500, it can easily cause adverse androgenic side effects.
