I used KC's Easy Kit with PEG for Primo Acetate. It went in at 100mg/ml without any problems. But, when it cooled down, it fell out/crystallized. I'm going to reheat and add PEG to make it 75mg/ml and if that doesn't work, 50mg/ml.
I made the methenolone enanthate. It was no problem at all. I just made it like I would make test prop. Even though it is methenolone ENANTHATE it converts more like prop. I used 5%BA and 15% BB for 100mg/ml. Turned out great. Smooth and painless. Hope this helps.
