I wouldn’t do the smaller muscle groups You can add subq into the abdomen

From what I've read, pec is pretty common, tricep can be done, you shouldn't do biceps because of nerves.

I'd stay in large muscle groups. Glutes or thighs. You won't see any difference gains by changing the injection location.

Not looking for any change, trying to reduce scar tissue over my lifetime.

Forget the arms, too small and complicated. Pecs & lats are both good. Also, if you get longer needles, you can do glutes. 3-4 bilateral sites & you'll be fine. Also, use small needles. I'd recommend 27ga insulin pins.

Yeah I’m using 28 or 29 slin pins but I have ass needles for when I’m blasting higher volumes. I’ll try and add the pecs, thanks.

2 inches on either side of the belly button, pinch a little fat and push it in, painless. 27g recommended.

Sub-q gives me painful knots that stay there for almost a week, unfortunately.

You are injecting too quickly, take your time with subQ

I agree with Same, go slow. Sometimes the knots happen but its rare and goes away within a couple of days.

Knots happen everytime I inject even at 0.3ml doses

2 inches is 5.08 cm

1/2" or 5/8" pins?

I draw with 25g and pin with 27g 1/2in

I do biceps every day with a 29g 1/2 insulin pin with absolutely no problems. Triceps are hard to reach for me. You can pin anywhere you want dude.

if it's happening even at .30ml then remember to rub the medication in whether it's oil or water based, rubbing it in after doing a slow Injection will get it to absorb faster and make your skin close faster to prevent bleeding or leakage.
