I use a 23 gauge 1inch. I usually pin my delts. I get a knot every once and a while. I do the usual massaging of the spot after. Heating pad every once and a while. But was wondering do people pulll there pinz out quickley after injection. or slowly after injection. Ive experimented with both, but still get swelling and a knot . I was going to try a 25 gauge next cycle when my guy can get them maybe it will have less sweling due to smaller diameter. Anyone have any other advice to keep swelling down and getting minimul knots ? Thanks . By the way ive been doin 2.5cc Test Cyp = 625mg. Thanks people.
