Just wondering what people are generally using. I have slin and 27G pins. I could see using slin for bi's/tri's/pecs/lats but if I do 20mcg in both sides, I don't know how I feel about using a slin needle on my glutes and other areas. What's everyone else doing?? Also, how often can you come back to the same muscle using the new mix? Thanks!

I've always used 31g slin pins (1/2") for IM. Any slin pin will work for for bis, tris, delts, pecs, quads, lats. You should be fine unless you have a higher BF%.

Yeah, you probably would need a 1" pin for glutes. I don't know why you'd want to shoot glutes with IGF. The idea of going IM is for some site-specific growth. I'd rather have any site specific effects work on a visible muscle than my butt cheeks.

Haha thanks! That's what I figured but I just thought I would run out of spots to poke quickly!
