YK-11
,
YK-11 SARM is a compound recognized as a myostatin inhibitor that promotes muscle growth. It is regarded as a potent SARM with effects comparable to testosterone. Its primary focus is on enhancing the prostate, reproductive organs, hair, libido, and overall physical development. Each bottle contains 90 capsules, with each capsule offering 5 mg of the compound, which results in fewer side effects. While most bodybuilders typically consume 10-15 mg daily, experienced users may take up to 30 mg. Experts recommend dividing the dosage for optimal outcomes.
