I think I know what you are talking about, I have never heard the term Azolin but if it is Androisoxazole (17beta-Hydroxy-17alpha-methylandrostano[3,2-c]isoxazole) then I do know of it. Actually it was the first PH I was going to bring out (a mild anabolic) and I like it a lot, but the price of it is quite expensive and my chem house wasnt definitely sure on how to make it. Since I have a list of about 10-15 other ones I am working on, I put that one on the back burner. I have been told it was easy to make by a different chem house and when I tested the sample it was just winny.
Bolasterone, is a pretty strong compound and currently I dont think it is tested for but there is a contamination issue with another compound that I cant think of at the moment. so you wont know you have what you want till you get it tested as well. Since I dont have $6-10k to waste on compounds that can have contamination problems, and I went through enough of that with the Methyl-1,4ADD I will stick to some that I know I can do and not have to worry. Dont worry theer are still plenty to do. lol
