Prime Male verdict
The honest one of the bunch — and it grades better because it doesn't play the 'equivalent' game. Real 300mg KSM-66, real 120mg ginseng, real 1,600mg D-aspartic acid, solid zinc and vitamin D. Several are still under their studied dose (the ashwagandha and ginseng are half), but these are actual amounts, not raw-herb inflation. It's a fair formula sold at a premium; the same actives cost a fraction bought loose.
TestoFuel verdict
Same cheap-herb skeleton as the rest — D-AA, D3, zinc, magnesium, B6, fenugreek — plus oyster extract (which is really just more zinc). Fully disclosed, and graded on the real numbers only the vitamin D and boron hit their doses; everything else is a fraction of the studied amount. Nothing here justifies the price — the effective minerals are dirt cheap bought loose.
