IM injection problem, plunger won't depress without excessive force

[OceanoDepths]

are u lean? try slin pins in a bunch of new muscle areas u havent hit yet- traps, rear delts, diff parts of quads etc... give those "goto" spots sum time to chill...oh yea, are u storing the bottle in a cold atmosphere?

About 11-12%, but when I started trt oh so long ago (at about 18-20%) I even used slin pins on my legs/upper body with success every time, hold almost all my fat in my gut so the small pins have always worked for me.. Switched to bigger pins only for my blasts cause of all that prop.. Will be using other spots though for the time being, give the usuals a break.. Oils are stored at room temperature and when I load pins I let em sit in a heating pad for 20 min. or so before injecting..

Appreciate all the responses bros! Love this community
