Research peptides vs compounded peptides: what's the difference
The same peptide name can describe a research chemical, a compounded prescription or an approved drug. They are not the same product and are not regulated the same way.
The same peptide name can mean three different kinds of product, and buyers often compare them without knowing it.
| Approved drug | Compounded | Research peptide | |
|---|---|---|---|
| Who makes it | A drug manufacturer | A licensed compounding pharmacy | A chemical supplier |
| Needs a prescription | Yes | Yes | No |
| FDA reviewed the product | Yes | No, but the pharmacy is regulated | No |
| Labelled for human use | Yes | Yes, for one patient | No ("research use only") |
The protections a buyer has are very different in each group. Every peptide page on Upzo says whether an approved version of the drug exists.

Here is what changed and what didn't.HPLC vs mass spec: what each peptide test actually provesHPLC gives you a purity number. Mass spectrometry tells you what the molecule is. A COA that only has one of them leaves a question open.
