Just because you will read shit here ill repost what someaone said here in this forum...
I agree and have had this discussion about not properly heating (and stirring) can cause pip. I use to make
test enanthate 400 and it made an Easter egg on my ass. I walked around like I had those pirate stick fake legs for legs. After trying call sorts of stuff like recipe wise, I even went 100% eo for carrier, and added higher solvent levels. Still I got Easter eggs. I then made friends with a former producer. He told me my problem was how long I was heating and not having an auto stirring set up. I had been heating to sterilize and just used a glass rod to stir it a bit here and there throughout the process. I'm not 100% which part made the pip go away but I always heat it to about 225-230f, and auto stir for about 45minutes to an hour. I have never had any sort of PIP again and I went back to just 2%ba, 18%bb and rest mct or mig.
His producing was before my time so I don't really know just how crazy it got but he has been able to answer anything I have ever posed to him.
Full of info I wish I could just carbon copy and digest into my experience.
this guy was just talking bout pip and temperature, but its not just pip, you dont need more than normal 20% BB and ur carrier oil... here u will read pple using 24 28 30 34% of BB just because they want to dissolve with no heat, i would like to know how do they make a suspension, using 90% of BB dunno, st has a very high melting point, anyway... do it and see if it works. ive only seen TNE in suspension
