PHARMA NAN D 300 — Pharmacom Labs

Active Ingredient: Nandrolone Decanoate (Deca)

Concentration: 300 mg/mL

Form: Injectable, in multi-dose vial / ampoules 

“Deca” (nandrolone decanoate) is often promoted as a “classic mass builder” in the Pharmacom Labs injectable line. 

The product is marketed as optimal for mass / bulk gains, with strong capability for promoting “massive bulk muscle gains.” 

It is claimed to cause significant water retention in muscle tissue, contributing to rapid size increases during its use (“Due to the significant retention of water in muscles … overall bulk mass increases occur remarkably fast.”) 

The brand suggests that nandrolone decanoate has relatively mild androgenic / virilizing effects, compared to some other steroids — giving it appeal for users seeking muscle growth with somewhat moderated androgenic side effects. 

It is also claimed that nandrolone may help with joint relief / recovery, sometimes marketed as “good for joints” in the context of heavy training. 

The product is often included in the “Basic / Injectable” line of Pharmacom’s catalog, under “Nandrolones.” 

Suggested pairing / stacking: Pharmacom advertising mentions combining PHARMA NAN D300 with long-estered testosterone compounds for better synergy.
