The 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.
