I recently ended my Superdrol 3 week cycle and started taking Nolvadex. But today, on day 2 of nolvadex I'm feeling unusual. After taking 20mg, im kinda sweaty, shakey as hell and have a small pain on the left side of my abs, like under my left oblique. Is something wrong with the stuff I got possibly? Are some people semi-allergic to this stuff? Definately not agreeing with my body I think.
