I've always used 22 gauge 1.5 inch pins for my glutes. My friend just told me that him and his friends are using insulin needles to shoot deca in their arms. I told him that he can't use those. He says I'm wrong. Is it okay that he uses those for shooting deca?
It's going to take an awfully long time for you to push deca through a 29-30G needle. I don't have that much patience. But it may be possible if you heat up the oil and have some free time...
