Peptides are the most confused corner of the aesthetics and wellness market, and 2026 made it worse rather than better. The FDA signalled movement on a group of peptides including BPC-157, and a large part of the industry read that as permission.
It is not permission. Regulatory limbo and a green light are different things, and the difference matters if you are the one administering.
How peptides get classified
Compounding from bulk drug substances runs through FDA lists:
| Category | Meaning |
|---|---|
| 503A Bulks List (Category 1 outcome) | May be used in compounding by a state-licensed pharmacy |
| Category 2 | Substances with significant safety risks — not to be compounded |
| Category 3 / under review | Nominated, under evaluation, no permission granted |
| Not on any list | No pathway. Absence is not permission. |
That last row is where most peptides sit, and where most operators get it wrong. A substance not appearing on a “do not compound” list has not thereby been approved for compounding.
What actually happened with BPC-157
In late 2023 the FDA placed BPC-157 in Category 2, citing safety concerns including immunogenicity and an absence of human clinical data. That closed the door.
In 2026 the FDA signalled its intent to remove a group of peptide bulk drug substances — BPC-157 among them — from Category 2. The Pharmacy Compounding Advisory Committee took up BPC-157 at its July 2026 meeting and narrowly recommended it for the 503A Bulks List.
Here is the part the marketing skipped: removal from Category 2 is not the same as addition to the list of substances you may compound. Coming off the “do not” list without being placed on the “may” list leaves a substance in limbo — and listing decisions run through proposed and final rulemaking, which had not completed.
A narrow committee recommendation is advice to the agency. It is not a rule.
What that means for a practice today
If you are dispensing or administering a peptide that has no completed pathway, you are operating outside the protection that sections 503A and 503B provide. The seller’s confidence does not transfer to you — the practice that administered it carries its own exposure.
Three questions worth asking about any peptide on your menu:
- Is this substance on the 503A bulks list, or has rulemaking completed placing it there?
- If a pharmacy is supplying it, under what specific authority?
- Is the active ingredient pharmaceutical grade, with documentation — or is it labelled for research use?
“Research use only” is not a workaround
A significant share of peptide product reaching clinics is sold as research material. That labelling states the contents are not intended for human administration, and research-grade active ingredients are not permitted in human drugs.
Buying it through a clinic account rather than a consumer website does not change what it is.
The marketing problem sitting on top of it
Even where a peptide can lawfully be compounded, the claims made about it usually cannot be substantiated. Healing, recovery, longevity and performance claims are exactly the language that draws regulatory attention, and compounded preparations are not FDA-approved products regardless of how they are described.
If your website makes a therapeutic claim you could not defend with evidence, the compounding question is not your only problem.
How to hold a defensible position
- Maintain a written formulary and know the status of every item on it.
- Get the supplying pharmacy’s basis in writing, not over the phone.
- Re-check status on a schedule — this area moves, in both directions.
- Keep marketing claims inside what the evidence supports.
- Be willing to remove an item. “We stopped offering that” is a much better answer than the alternative.
Where MDside sits
We maintain the formulary for the practices we support, confirm the supplying pharmacy’s authority rather than assuming it, and update protocols as listings change. Where a substance has no completed pathway, our providers do not prescribe it — including when a competitor down the road is advertising it.

Frequently asked questions
Is BPC-157 legal to compound now?
Removal from Category 2 is not the same as being added to the list of substances that may be compounded. Listing runs through rulemaking, and an advisory committee recommendation is not a rule. Verify current status before relying on it.
If a peptide is not on any FDA list, can I use it?
No. Absence from a prohibited list is not permission. Compounding pathways work by inclusion, not by omission.
My pharmacy says it is fine. Is that enough?
No. Ask for the specific authority in writing. The practice administering the product carries exposure independently of the supplier.
What about peptides sold for research use?
That labelling indicates the material is not intended for human administration, and research-grade ingredients are not permitted in human drugs.
How often does this change?
Frequently, and in both directions. Treat any peptide status as a point-in-time answer and re-verify on a schedule.
