Among the synthetic injectable anabolic steroids – compounds other than testosterone, the natural product – trenbolone is perhaps the most remarkable. Of them, it is certainly the most remarkable for mass gain, strength gain, and contest preparation.
Trenbolone Side Effects
To some extent, there is a price in side effects to be paid for this, but not nearly to the extent that many imagine. While a few find trenbolone problematic for reasons of increased aggressive tendency, night sweats, or reduced aerobic performance, most find these side effects slight and easily managed, or non-existent for them personally.
Avoid Trenbolone-Only Cycles
Trenbolone, whether as the acetate (Finaplix, Finajet), enanthate, or cyclohexylmethylcarbonate (Parabolan), should not be used as the sole anabolic in a steroid cycle. Mass gains are greatly limited when this is done. Instead, trenbolone should be stacked with Dianabol, Anadrol, or testosterone as the most common and highly suitable choices.
Trenbolone and Suppressed Estradiol Production
A second reason is that estradiol levels fall too low when trenbolone is used alone. This occurs because natural testosterone production is suppressed when using trenbolone, and this in turn suppresses natural estradiol production. And since trenbolone itself does not aromatize (convert to estrogen), then there is very little substrate available for aromatization, and estrogen production becomes abnormally low. This can cause joint, mood, and libido problems.
