So, years and years ago when I first started cycling, I was given a batch of 25 gauge 3cc pins. It was pretty tough to push gear through them, so, when I started ordering them online, I went with 3CC 23 Gauge. I don't mind the larger gauge, even in my delts, but it's super painful to pin my quads and glutes. Recently, I purchased a bag of 100 25 gauge slins for bpc injections (that's all they had). In my attempt to man up to the quad injections, I figured, I'll start with one of those 25s. I couldn't believe how easy it was to push gear through it, plus the pain was minimal (hardly at all - even in the glutes). The only downside is that it's 1cc.

So, maybe the oil these days are just thinner, but I remember just so hard to push it.. Is it really easier with a 1cc or what?

thanks!
