Again, any androgen will affect the HPTA. And way more so if it converts to estro or has progesterone properties also (which winny doesnt). So-yes. Not as bad as some other AAS.
If you read my post, I never said it wouldn't shut down HPTA. I said it wouldn't to a huge extent, maybe I should have put compared to a lot of others such as d-bol or deca.
