Masteron propionate

Drostanolone propionate is a prodrug of drostanolone . [1] Like other AAS, drostanolone is an agonist of the androgen receptor (AR). [1] It is not a substrate for 5α-reductase and is a poor substrate for 3α-hydroxysteroid dehydrogenase (3α-HSD), and therefore shows a high ratio of anabolic to androgenic activity. [1] As a DHT derivative, drostanolone is not a substrate for aromatase and hence cannot be aromatized into estrogenic metabolites . [1] While no data are available on the progestogenic activity of drostanolone, it is thought to have low or no such activity similarly to other DHT derivatives. [1] Since the drug is not 17α-alkylated , it is not known to cause hepatotoxicity . [1]

presents you another cutting cycle for summer which will make you look hard and solid. As a base we will use testosterone enanthate however you may replace it with testosterone propionate as in some individuals enanthate will make visible water retention but I dont think this is a problem as you dont prepare for the contest, right? 🙂 On the other hand switching to propionate will bring you another headache as you will have to inject it EOD plus you will inject Primobolan ( Methenolone Enanthate) 2-3 times per week so having to inject primo and test propionate will keep you really busy and will not give your injection sites enough time to rest.
