Being old school, using only deca, test e, tren 2 cycles a year, was looking around at different suppliers. We have all mixed our gear to save from pinning that extra time. My question is, when some of these products have multiple solutions in them, do they separate? Or do the formulas play well together? Some of the suppliers, if true, have awesome mixtures for just two pins a week. Or has this been out a long time, and I just need to get caught up with the times. Thanks all, happy pinning...
