Okay well just an update.
1/20/EO 250mg/ml Trest seems to hold just fine, brewed easy with minimal heat initially. No problem
I'm wondering if the test sample of 1/20/EO 250mg/ml tren I did that I accidentally used GSO instead of EO (similar bottles I had right next to each other, didnt even realize I pulled it out). So that crashes a lot. maybe it was 1/20BB, I do know 1/20/MCT crashes.
Regardless, I brewed 1/40BB/EO 250mg/ml tren a and it's held up beatifully. Zero PIP (some pharmas use 40-50% BB, you can always test shot some bb too...). Barely needed any heat at all and dissolved easily. I ran it on a magnetic stir overnight just to be sure it'd hold even with some chillier room temps.
It's completely pale yellow as opposed to burned orange, the nicest tren I've ever seen.
In the future I wonder if 1/30BB/EO would be stable. Maybe even 1/20BB, maybe I'll try to taste test that sample I made to see if I really did add BB vs GSO...
