S-23 Powder Dosage

Dosages of S-23 can vary, and they will be very dependent on what the goal is. For instance, if a user were looking for muscle building and fat loss, a dose of 15-25 mgs per day would be appropriate. On the other hand, if someone was looking to use it for the contraceptive effects, a higher dose of around 50 mgs per day would be more effective. Nonetheless, this is not recommended because there have not been studies done on humans to replicate the contraceptive effect shown in rats.

S-23 Powder Cycles

In spite of the fact that after 100 days the rats did recover natural testosterone levels, humans would need to run a full PCT (Post Cycle Therapy). Since S-23 causes severe suppression, I would always recommend the Perfect PCT.

S-23 Powder Side Effect

The main side effect of S-23 use is the suppression of natural testosterone production. This is what gives it potential as a male contraceptive, and also makes it very different from other SARMS. While ostarine (ostabolic), andarine (s4), and Anabolicum (LGD) may cause a mild shut down, S-23 is extremely suppressive. Consequently, this will be a major factor in deciding whether to use this SARM or opt for the more widespread choices. Unfortunately, there have not been any human studies, so not much is known on other potential side effects.

S23 Powder Stacking

Many users recommend adding S23 to the end of a cycle to help reduce body fat, increase lean muscle and create a dry, grainier appearance.
For this reason, it’s suggested to add S23 into the final 8 weeks of a 12-week cycle.
Many users report stacking RAD140 (Testolone) with LGD4033 (Ligandrol) to provide a powerhouse for building lean muscle and burning fat.
