i did a cycle of prop, enth and deca. im 3 weeks in PCT and i already felt shutdown after 2 weeks. i am doing the clomid/nolv protocol, but never did HCG. Deca prob shut me down. I was wondering if taking research chem cialis is safe? what dosage? would taking this medicine affect me perm and mess me up? maybe body will rely on it. anyone take viagra or cialis in pct?
