30 servings per tub, $1.80/serving. 27g protein per scoop (25g whey isolate + digestive enzymes). Research on post-training protein dosing shows an effective range of 20–40g (15 cited studies). Many competitor ‘protein blends’ land closer to 18g of actual isolate once fillers and amino spiking are accounted for. Finish the tub. If it did nothing, full refund.
