what is so good about retibol and the 10-12mg versions compared to syntrabol, which reports 200mg of isoinokosterone per tab? randy reports that retibol is good and i found a bottle for $20 and free shipping. is the syntrax stuff that underpowered, though? John U, are you saying by double dose you are taking 12 caps/day (2x the max dose)? at that rate the bottle would only last 10 days! this seems to be a very expensive suppliment. if i can’t find a good version of this for cheap, i may just stick to finasol. that definitely works (although i don’t keep my gains very well that i make off of a bottle)
