I am brewing some prop, while I agree that individuals react differently to Prop, after talking with Bonaparte he has advised me to use EO and has told me that a mix of EO/Oil will keep the test from crashing in the muscle much better than just Oil. He suggests a 2/20 BA/BB with a 50/50 mix of EO/Oil of choice (GSO in my case) He could be wrong but so far since joining this board everything the "KNOW IT ALL PRICK".. joke... has said has turned out to be correct so I am taking his suggestion.
