How do you handle state-by-state telehealth requirements?

What exactly does Direct Peptide Sales do?

We are a referral and introduction service. We verify your business and the states it serves, then introduce you to licensed telehealth prescribers and 503A or 503B pharmacies. You contract directly with them. We do not sell, price, prescribe, compound, bill, or ship any product.

How fast can my practice be introduced to a source?

Most qualified practices receive an introduction within one business day of applying. How quickly you go live after that depends on the agreement you sign with the prescriber and pharmacy you choose.

Nothing to apply, and we do not charge practices a fee. Product pricing, account terms, and any minimums are set by the pharmacy or prescriber you contract with, not by us.

Where do the peptides come from and are they verified?

Product comes from the licensed US 503A and 503B pharmacies you contract with. We only introduce sources that issue independent per-lot Certificates of Analysis covering identity, purity, sterility, and endotoxin. You can review sample COAs on this site before you apply.

Who handles prescribing, billing, and shipping?

The licensed prescriber and the pharmacy do. Prescribing is the provider's independent clinical decision, and dispensing, billing, and shipping sit with the pharmacy. We are not part of that transaction.

What if I'm not a licensed clinic?

Non-licensed wellness businesses such as coaches, gyms, studios, and nutrition practices can be introduced to a licensed telehealth prescriber who owns the clinical relationship. You never prescribe, hold, or dispense product.

How do you vet the sources you introduce?

Every source must be a named 503A pharmacy or FDA-registered 503B outsourcing facility, hold non-resident licensure in the states it ships into, issue per-lot Certificates of Analysis, and use prescribers licensed in the patient's state. We decline sources using research-use-only language.

Which states do you serve?

We make introductions across the United States and match you to partners that hold the right licensure for the states you serve.
