Absolutely no pain during triceps injection ?

[iGOTstrongBICEPS]

I just did my first triceps injection and i felt absolutely no pain. I used a 25g5/8 pin for my triceps , flexed , picked the meatiest part of my tricep which was the outer head then relaxed it and pinned the spot .

I felt absolutely no pain whatsoever so now im thinking 5/8 was too short . Any input ?

If you're injecting HGH or some other water based peptide it should be fine. If you're injecting AAS, oil based, it should be "deep" intramuscular. Your arm should be about 1" pins unless you have skinny arms. I've done Deca/Test P with 5/8" insulin syringes when I was in a pinch and it seemed to work fine.
