Hi,
How much time is needed for a muscle to rest before I blast it again at the gym? I don't need regimen advice. I just need to know if I need more than 48 hours of rest. I've heard that 72 is optimum, but 48 is sufficient. I'm hoping for what I'm doing this month that 48 is enough.
Do steroids speed up the repair/growth of muscles?
Thank you.
