The H in Pharma Tren H100 marks the ester: hexahydrobenzylcarbonate, the slowest-releasing of the trenbolone esters. Pharmacom Labs carries it in oil at 100 mg/ml and fills a 10 ml rubber-stoppered vial.
Trenbolone sits in the nandrolone branch of the androgen family and, unlike testosterone, is not converted to estrogen. Hanging the long carbonate chain off the molecule slows its entry into circulation, so blood levels move gradually instead of spiking.
Every Pharmacom pack carries a printed code that can be checked against the manufacturer's own register.
