So i just started a prop cycle, im doing 100 mg eod, and been injecting in my shoulders and lats, and about a hour later i get this weird tight feeling in my chest over my heart. never on the right side always the left, doesnt effect my feeling and it doesnt hurt that much. More just dis comfort. Ive done prop b4 and i never had this before. my question is has anyone ever had anything like this? doesnt effect my work outs at all just when im sitting doing nothing.
