I've always read about lethargy with pro hormones but in my case, made me feel like crap only the first days...like the first 3 days. AFter that everything went normal. Even the first 2 weeks gave those heart palpitations as dbol. And that's it. Libido has decreased but still pretty normal. That's how it works for me. I think a bridge of only 5 mg (1 pill) a day would be great!.
