Recently made a batch of Test phenyl propionate at 100mg/ml Totally painless and still holding but I used EO so I didn't really expect it to crash.
The next batch I will make with just GSO and see if it holds as I know some have reactions to EO.

Recipe for 100ml

power = 10grams
BA = 2%
BB = 20%
GSO = 41.5ml
EO = 28ml

EO was about 40% of total oil mixture

Happy brewing fellows.
