How much does it cost to private label a peptide serum?

At low-MOQ runs of 100–300 units, expect finished-goods costs of roughly $8–$18 per 30 mL unit depending on the peptide actives used, packaging choice, and fill complexity. Costs drop significantly at 500–1,000 units. Always request an itemized quote separating formulation fees, setup charges, and per-unit fill cost.
