Test cyp and test prop are 2 esters I would use some heat to dissolve after adding solvents to speed things up. I would never use heat on the raw itself, if that is what you mean. Add it to your solvent and then use low heat to dissolve it into your solvent. It only takes a few minutes in hot water. I then add my carrier oil. If your gear crashes after that, adding more bb to the finished product should solve the problem. The brew you are refering to, I brewed 200 ml of test cyp. Everything looked good, but it got cold that night and both 100ml vials crashed. I added an extra 2 ml of bb and 1/2 ml of ba in each , and that did the job. It never crashed again. I still have one left, and it is sitting pretty

That is my process.
