Bro. That is a fucking harpoon. There is no way you want to jab yourself with that. There are guys here who have done it...maybe someone will give a testimonial. Go to www.getpinz.com. They have the size you need. Probably a 25g 1" or 25g 1.5"
I tried to.... I almost got it in but didn't quite make it, it was extremely painful and when I pulled it out blood came gushing out. Don't do it, trust me.
i was using 20 guage for the first few weeks thinking it was small..
then ordered 100 25's and 100 23's all 1.5 inch.. and getpinz sent me 200 25's half 1 inch half 3/4 inch so the entire order was wrong.. dont understand how they can mix an ordeir up that bad.. i just ended up giving away all the 3/4 inch pins..
I got poked with a 16g in the stomach to get a culture taken from an abcess. It's a fucking spear and I don't see 18g feeling a whole lot better. No, the abcess wasn't AAS related, just a fluke health issue.
