Merchant Account for Peptides Business [Instant Approval]

A peptides business gets a high risk classification because the FDA scrutinizes both unapproved peptide compounds and compounded prescription peptides under 21 CFR § 503A/503B, because the chargeback exposure on "for research use only" products is structurally higher than mainstream e-commerce, and because card networks treat MCC 5912 (drugs, drug proprietaries, druggist sundries) and MCC 5122 (drugs, drug proprietary, druggist sundries — wholesale) as restricted MCCs that require explicit acquirer approval. Acquiring banks also weigh whether your peptides are sold for genuine research use to credentialed buyers, whether you maintain physician oversight on compounded GLP-1 sales, and whether your label language complies with the FDA's evolving guidance on peptide marketing.

Opening a peptides merchant account differs from opening a standard low-risk account in three ways. First, underwriting takes 3 to 5 business days rather than instant approval, because the acquirer reviews COAs, physician supervision agreements, LegitScript certification (if applicable), label compliance, and your processing history. Second, pricing typically ranges from 3.5% to 4.95% rather than the 2.6%–2.9% flat rate aggregators offer, because the acquirer absorbs additional dispute exposure on RUO products. Third, the account issues a dedicated MID that belongs exclusively to your peptides business, so the account cannot be terminated for serving the peptides vertical the MID was approved to serve.

2Accept underwrites peptide merchant accounts for RUO peptide retailers, compounding pharmacies, telehealth GLP-1 platforms, and gray-market research chemical suppliers across the United States. Applications are reviewed by a dedicated peptides underwriter within one business hour, approved in 48 hours to 5 business days depending on compliance complexity, and integrated through gateway API, hosted checkout, or Shopify after signing the merchant processing agreement.
