The math stays independent
How LiftRadar ranks
Retailers charge different prices for different container sizes and serving amounts, so sticker price alone cannot show value. LiftRadar normalises each rankable product to the category's useful unit—per gram of protein or creatine, per serving, per can, per bar, or per fluid ounce—compares it consistently, and orders only fresh offers. Sponsorship never changes the result.

Normalized comparisonsCompare cost per gram, serving, can, bar, or fluid ounce.
48-hour freshness firewallOffers older than 48 hours cannot remain in current rankings.
Straight answers
Common questions
Does LiftRadar sell supplements?
No. We compare current retailer offers and send you to the retailer you choose.
What does “best value” mean?
The lowest verified normalized cost for the category—not the loudest discount sticker.
Do commissions change rankings?
Never. Eligible offers are ordered by the same published math.
