A while back a bro of mine converted his surplus 4-AD powder into an injectable and had LOADS so he shared with me for a second opinion. The burning was mild (very manageable) and the effects were likened to test suspension rather than deca. Contrary to what others believe it proved to be VERY anabolic as I had a 6 pound gain in 2 weeks (this is good for me since I'm already "chemically enhanced"). I was doing 50 mg twice per day...
I'll post a 4-AD injectable recipe as soon as I write it up. The some of it is that you can get 50 mg/mL in (oil) solution with 5% BA / 20% BB but beyond that I can't make any claims or guarentees. That is the concentration that I used and I haven't brewed any myself. Definitely worth looking into
BTW, the 4-AD is harder to get into solution than fina since it lacks an ester which would make it more lipophilic.
