Ive been taking 5iu /day(kigtropin-prob just blue tops) for around 4 weeks, Ive just started ghrp-6 100mcg and cjc 100mg for 2 days. Ive started getting a discomfort / strange felling in my lower chest . Its not a pain but like a small throb-tightnes when I exhale about every 10-15 breaths,its not my heart or anything. It feels muscular also the joint of me big toe and also the back of my ankles has started hurting. None of these are a problem , I just wana make sure there's no big problem. Is this normal?
