Naming is plain on this one: Trenbolone 100 from Dragon Pharma is trenbolone acetate at 100 mg/ml, ten millilitres to the vial, with the figure in the title reporting nothing more than the concentration.
Acetate is the quick-release member of the trenbolone family. The ester is cleaved inside a short window, so the hormone arrives and clears faster than the enanthate form of the same molecule does. The solution is oil-based and drawn from a rubber-stoppered vial. Dragon Pharma also produces a half-strength version under a near-identical name, which makes the number the thing to check.
