small "click"-sound when pin goes through

[sniperdeath]

Yo! I got a question, whenever i inject into delts or biceps/tripceps the skin makes a small clicksound upon pin-penetration. Has this anything to do with how stretched my skin is, i.e from training and such, or is it just normal, and something that would occur even in a bulker? i'm pretty lean now, might it be the reason why i "click"?

Thanx for the thread, dogg! Ok, i'll use the ass, but it's a goddamned pin-cushion by now, lol. I rotate quite often at times when i use 2 or more juices. I got 0,6mm and 0,7mm, don't know what gauge it is tho. mine are swede-made, so it's not specified. I used a 1,2 mm pin once, the kind that u normally use to draw the use out of deca-bottles and other ones with rubber-lid
