S-23 description

1. developed by gtx, s-23 is an orally active nonsteroidal sarm with a very high binding affinity to androgen receptors. this makes it stronger than other popular sarms like ostabolic (mk-2866) or andarine (s-4).

2. therefore, the main effects of s-23 are increased muscle mass, decreased fat mass, and a decrease in the size of the prostate.

3. additionally, in a study done on rats a dose equivalent to 15 milligrams (mg) for a 180lb male was shown to also increase bone mineral density, as well as promote muscle mass growth and fat loss. hence, s-23 is versatile in that it can be used for bulking and for cutting.

alternative uses

1. study showed s-23 to be used as a male contraceptive in which six rats were given a dose of 0.1 mg per day for 10 weeks. as a result, both lh (luteinizing hormone) and fsh (follicle-stimulating hormone) levels decreased.

2. these effects were statistically significant, since four of the six rats had no sperm in the testis. what's more, none of the rats was able to impregnate a female rat during mating trials.

3. however, this contraceptive effect was temporary - after just 100 days from last dose the infertility was reversed, and there was a 100% pregnancy rate.

dosages and cycles

1. 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.

2. 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.

3. nonetheless, this is not recommended because there have not been studies done on humans to replicate the contraceptive effect shown in rats.
