I'm looking to add a few pounds of LBM and have been thinking about HGHUP or Prime. Now, both are RIDICULOUSLY hyped up and I haven't tried a single USPLabs product that worked other than PowerFULL. Even that only helped me sleep better. My libido did not change, I gained zero strength, and nothing else happened at all. Waste of $$ for me. That's why i'm VERY hesitant to try Prime. Anyone have any REAL UNBIASED feedback on these 2 products or any others for that matter, that put some more mass on them? Company reps, don't even bother responding.
