In short, turns out I already had it. I didn't realize until I looked closely at the bottle. It's from a local pharmacy.You got it already? That's awesome. I am actually going to try some larger gauge needles. 31g isn't going to fly with this stuff long-term. It took me several minutes to fill .2 ml yesterday.
Longer story: I have tried it before in small quantities (10-15mg at a time), which is why I was hypothesizing (hoping) that perhaps there is some threshold below which someone like me may feel bad from injecting, and above which I feel OK. Possibly mediated by some threshold needed to aromatize properly? Or, maybe there are competing effects, one of which is anti inflammatory and that with a larger injection, the anti inflammatory properties mitigate whatever causes me to feel bad on smaller injections?
I usually, but not always, feel OK with Xyosted. But, being able to tolerate a multi use vial would be much cheaper and more convenient.
