Influence of testosterone on Yaz
I have started gymming quite a while ago and want to take extra supplements. One of them are USN Hardcore Protein gh, it contains Creatine and Tribulis Terrestis. Will one of these products counteract the efficacy of Yaz the contraceptive? I've read that Yaz stops the body producing testosterone (used for building muscle), if so what can I then add for building muscle?
