Much of this manufacturer's testosterone range is built at 300 mg/ml, and Pharma Test E300 follows the pattern - a 10 ml vial of testosterone enanthate at that strength, three grams to the bottle. It sits between the common 250 and the heavier 400 mg/ml preparations.
The naming runs the same way through the whole Pharmacom Labs line, with the ester and the strength spelled out in the suffix. Enanthate itself is a long-acting ester of natural testosterone, dissolved in oil for intramuscular injection; the chain attached to the hormone is what delays its release and makes the product a depot.
