Pharmacom code their nandrolone as Pharma Nan, the letter and number spelling out the contents - D for decanoate, 300 for milligrams per millilitre, in a 10 ml vial.
Every unit leaving the lab carries a unique code that can be checked against the manufacturer's own records, a practice the house has kept up for years. The steroid behind the code is 19-nortestosterone bound to a ten-carbon ester that holds back release for weeks. Nandrolone's twin reputations - comparatively easy on blood lipids, and capable of raising prolactin - both belong to that molecule rather than to the ester.
