Pharmacom Labs runs its testosterone blend at 300 mg/ml, a step above the classical 250, filled into a 10 ml sealed vial. Pharmacom is known in this segment for printing a unique code on every unit so that a buyer can check it with the producer before use.
What is in the oil is testosterone attached to several different esters. The mixture is built so that release overlaps: the shorter chains are cleaved early, the longer ones keep the hormone in circulation afterwards. It is injected into muscle and has no oral counterpart in this form.
