I know I'm going to get flamed for this, probably. But, as a couple people know, I've bought the formestane powder and just made an injectible gel out of it. I've never got it to stay in solution, so heat and shaking is in order. I've used it here and there (many many injections over the years, usually about 1/2 to 1 cc of a 300 mg. per mL concentration- I mean, hey, it won't stay in solution at a low concentraition anyhow...). I've liked my results from it. I sometimes use it for pct/ tapering. The only thing is, that you'll lose some of it in the needle with smaller needles (a portion won't make it through- depending on what gauge pin and how concentrated your mix is). I know I'm crazy, but, knock on wood, no problems whatsoever.
Just throwing this in. I'm not reccomending it for anyone else.
