GOOD QUESTION Everyone here seems to have a different opinion but the general consensus is between 23-25g and 1-1.5" long the length depends on your bodyfat and again preference. With Glutes I like 1" for Quads and delts 5'8" but that's me. Also I go 25g on all pins. here is what I do I Buy 3cc Luer lock syringes with 20g Pins and another box of 25g 1" pins only, then you can load the syringe fast and get straight to it. remember you don't have to put it in all the way so the 1" will cover you for all areas.
If I was to inject into my quad with a 1" needle, how far in do I push it?
The larger gauges will load faster you can push or oil out of the syringe with a small needle much faster than you can draw it in. The reason you change needles is because when it first punctures the rubber seal it dulls it down significantly. So when you're ready to pin your self it's like trying to do it with a dull nail lotsa guys don't change them but it goes much smoother and less painfully if you do
just a questions for us Vets... should we even be giving this guy advice... I mean I understand the nature of the forum to build knowledge and share advice. However, this guy is running gear with zero knowledge of what he is doing... I wouldnt be surprised if his shit he got is bunk and he gets staph at the end of his cycle.
i like to pinz with all kinds of different pinz..got hooked on slin pinz and 25g 5/8 for many years..but scar tissue is a issue now in delts..so i use a 25g 1 1/2 pinz for delts..once i hear the cracking of my scar tissue stop i know i'm home free..so thats bout the whole pin with maybe 1/8 or 1/16th of the pin out..
traps if you have big ones work well with slin pins or your pecs maybe tri's...i have to go for all the places my concrete flexibility will allow me..do quads some with 25g 1 or 1 1/2 inch too..i just kinda stab around the body where i can reach without my chest cramping up..
