1 cc max per injection cycle
1 cc max per injection cycle is the turnaround.
Staying under is more comfortable, going over it like
1.5 cc or 2 cc or more means more pain.
Some are more tolerant to pain, some more sensitive.
If you are a sensitive guy then that is though luck.
It is not only the needle giving problems (phobia), but also the stuff and important when your arms get tighter and tighter, you are not so anxious to hit them again and again. Taking a painkiller might help also.
Some say bi's and tri's injections are easy, and they are right. Right now shooting the arms with Winny is easy, because it's a roid.
You could go for 1 cc at a time and this for twice a day, like 1 cc in left arm and in the afternoon (or whenever) 1 cc in the other.
