Super legit product. I had gyno From a prior sarm cycle and it flared up really bad on my current test cycle. 2.5 weeks into taking this the gyno has completely disappeared and I’ve had little to no water retention despite a high does of test and a high carb diet. 10/10 recommend if you’re having any estrogen related side effects.
