YK-11 PRO by Core Labs X: the myostatin-inhibiting SARM in high dosage
YK-11 plays a special role among SARMs (selective androgen modulators): The substance only marginally modulates the androgen receptor, but it very effectively inhibits the activity of the myostatin gene. Since this gene is responsible for limiting muscle growth, the administration of YK-11 causes extremely strong muscle growth. Animal experiments suggest that this not only thickens existing muscle fibers (hypertrophy effect), but also leads to the formation of new muscle fibers (hyperplasia effect). This could mean that muscle building is significantly easier even after discontinuing YK-11. In any case, YK-11 is a very potent anabolic steroid. Muscle gains of up to 10 kg in a period of 8 weeks are not uncommon under the influence of YK-11. These are accompanied neither by water retention nor by a suppression of the body's own testosterone production.
What makes YK-11 from Core Labs X special?
Because YK-11 is still largely unexplored, there are currently no binding dosage recommendations for the substance. In bodybuilding, doses as low as 5 mg daily have proven effective; higher doses are even more effective. Core Labs X YK-11 PRO therefore contains 10 mg of YK-11 per capsule. Those who tolerate this dose well can increase their intake to 2 capsules daily. An even higher dose is risky because the main active ingredient (17,20-[(1-methoxyethylidene)bis(oxy)] 3-oxo-19-norpregna-4,20-diene 21-carboxylic acid methyl ester) is liver toxic due to 17-alpha alkylation. Although YK-11 PRO contains the liver-protecting antioxidant NAC (N-acetyl-L-cysteine) and vitamin E TPSG, YK-11 should therefore not be used for longer than 8 weeks.
