Esiclene is not known for its results. It doesn’t have any strong anabolic or androgenic effect, which makes muscle building out of the question as a use for the drug. So what does it do? Bodybuilders use Esiclene to pump up specific muscles before a competition because injecting it directly into a muscle will cause that muscle to swell. The effect only lasts a few days and the injection is irritating, even painful, so its use is not highly recommended.
