Masteron Propionate

Drostanolone propionate (Masteron) is an injectable anabolic/androgenic steroid. It is highly androgenic and mildly anabolic. Drostanolone does not aromatize into estrogen and has similar properties to dihydrotestosterone (DHT). Drostanolone was originally developed to be used as an anti-estrogenic compound for treating female breast cancer. Drostanolone is irreversibly metabolized by the enzyme 3a-hydroxysteroid-dehydrogenase into an inactive form of 2-methyl-5-androstan-3-ol-17-one and promotes hardness, lean mass and muscle preservation during diet and cutting cycles.

Masteron brings a high quality look to the muscle and should never be left out of your stack.

Some of our injectables are highly concentrated and will produce pain during injection and afterward (PIP) if injected directly. To prevent this, you need to dilute (cut) these HIGH-MG injectables with a carrier oil/base.

Generally, anything above 250mg/ml should be diluted before injection.

How to Dilute:

  1. Determine which base you need:
    Look at the ingredients list on the product page OR on the label.
    Made with Grape seed oil (GSO)? Dilute with Sterile Oil.
    Made with PEG/MEG/Glycol base? Dilute with PEG/MEG BASE.
  2. Mix your product with the corresponding base in a syringe (or a new sterile vial).
    Initially, mix with a 1:1 ratio, diluting more if needed.
    Example: Mix 0.5ml of Gigatest 750 with 0.5ml grape seed oil in the same syringe.
