If you had BB (benzyl benzoate), I would probably go with some of that instead since I believe it causes much less injection pain, but if BA (benzyl alcohol) is all you have, go with that. You may want to heat it to help it all get into solution.
I made ethananate at 250 mgs./ml. with about 2% BA and 6% BB. Painless.
BTW I just did my first experiments with making test prop and no ester test in oil. I had to use a lot of solvent.
It took 5% BA and 15% BB to get prop into solution at 100 mg./ml. The no ester test was really tough. I had to keep adding solvent. I think it ended up being 6% BA and 20% BB to get 65 mg./ml.
Slightly frustrated with that, I took Billy Bathgate's advice and made a blend. Its 100 mgs. of test per ml., 50 mgs. prop and 50 mgs. no ester test. It took about 5% BA and 18% BB.
I did notice that heating the solution to about 150 degrees F for long periods and stirring it with a glass rod did help it slowly dissolve. Be patient, but remember that you aren't out of the woods until your finished product has cooled to room temp and remains in solution.
If anybody else has experience making prop and no ester test injectables in oil (or anything else for that matter), please share your experience regarding the amount and mixtures of solvent(s) you used, what concentrations you ended up with, and how much pain you get from them.
