Site Injection questions

alright well Im fixing to start a tren/prop cycle and was wanting to know what was the smallest pin I could in the diffrent sites and which seem to be the least painful. Im a pretty slim guy and I definatly don't want to go to deep and hit something but if I don't go deep enogh its gonna hurt like hell. her I could use slin pins for some, also herd of people using a 29 g 1/2 in for some sites. Please assist mods or somebody with experience.

29ga is way too small..it would take you forever to get the shit into your muscle. I always go with 25ga X 1.5" for glutes and quads. 23ga X 1' for everything else. Some people use 25ga, but there really isn't much of a pain difference and the juice goes in quicker w/a 23ga. IMHO.

I like to use 25g 1" pins for all my site injects. I would not try and use a slin pin oor a 29G.

Thanks guys, since I only weigh 170 and don't have much body fat at all (under 10%) should I use a smaller lenght on any of the sites ?

yeah that would be fine, 23 or 25 ga X 1"....doesn't much matter, just push it in all the way.

23-25...nothing smaller IMO.
