Prograde Pharmaceuticals SARM S4 (60 capsules)

S4 is a SARM developed by the same company who created Ostarine. S4 was created as a male contraceptive and to prevent muscle wastage, osteoporosis and prostate enlargement.

It has been picked up by athletes as a strong compound to create muscle, while lacking many of the side effects usually associated with prohormones and steroids.

S4 has around one-third of the binding affinity of testosterone to the androgen receptor, but also has the effect of making the user's own testosterone exert a greater effect than normal on protein synthesis and muscle mass. S4 is the most research SARM available, with multiple studies confirming its effects. S4 provides greater muscle building potential than DHT - the strongest male hormone men naturally produce.

While helping to build muscle, one of the side effects is that individuals actually lose body fat.

Actual amount of fat lost is dependant on the genetics of the user, but it increases the body's ability to oxidise fat. S4 also has the effect of “drying out” the muscle in the same way the anabolic steroid Winstrol would, which means it can be great as a hardener towards the end of a cycle or pre-contest.

S4 is not liver toxic, so a liver support such as milk thistle is not necessary. S4 is a mild anti-oestrogen and will lower oestrogen levels, it has been reported to help prevent gynecomastia (development of male breast tissue).
