Tri-tren is an injectable steroid which contains the hormone trenbolone in a blend of three different esters. This preparation contains 50mg/ml trenbolone acetate, 50mg/ml trenbolone hexahydrobenzylcarbonate, and 100mg/ml trenbolone enanthate.
This combination of esters makes it possible to see results very early on in cycle, due to the acetate ester. The other two slower acting esters then enable results to stabilize over the duration of cycle. Bodybuilders using this product typically use a dosage schedule of every other day to help keep consistent blood levels.
