Im trying to get my biceps bigger, ive changed my bicep workout and they are gettng a little bigger but i was wondering if i did some spot injections into them if it would help them growth and if the amount of growth is worth it? Im taking test e 500mg a week so i was thinking on my next injection day if i should do 250mg into each arm? Also do your biceps have good receptors or will i be wasting a shot?
