Trebasedrol 50 (Trenbolone Suspension) is pure trenbolone with no ester attached. Trebasedrol 50 won its reputation as a perfect pre-workout stimulant to increase aggression and power for extreme work-out sessions and competitions. We highly recommend to always use trenbolone in stack with testosterone, because it instantaneously shutdowns your HPTA, which results in suppressing production of endogenous testosterone, which is the male’s primary sexual hormone and should always be present in his body.
