probably cause high estrogen is water weight which helps lube the joints.. thats why people feel better on deca and horrible on winny.
also i will say that drugs like help with your joints and are anti-inflammatory are bad news. inflammation is necessary to help speed up healing, its your bodies way of healing itself.. shut that off and you are in trouble.
this is where the joint stack from NTBM pays off, you don't have to worry about sacrificing your future health.
