This is exactly what I could not find anywhere else. Printing the relevant bit and taking it with me.
Clinical perspective, offered as context rather than as advice.
Compounded has been just as effective for me. If compounded supply is the concern, the COA from my 503B pharmacy shows 99.1% purity. Verified by Janoshik.

I disagree that testing history is decisive. It tells you what a supplier did when they were being watched. Continuity of behaviour under stress — a late shipment, a failed test, a complaint — is more predictive than any run of good results.
Certified reference materials, analytical reagents, and research-grade standards for peptide verification. Trusted by laboratories worldwide.

Price comparison for compounded supply across sources I've used:
| Source | Monthly Cost | Type | Purity Verified |
|---|---|---|---|
| Brand (Ozempic) | $1052 | FDA-approved | N/A (pharma) |
| 503B Compounding | $132 | cGMP compounded | Yes (in-house) |
| 503A Compounding | $122 | Patient-specific | Varies |
| Research peptide | $42 | Not for human use | Often Janoshik |
I use the 503B option — best balance of quality, cost, and legality. The brand price is insane but insurance can help if you qualify.
Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
