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.

503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:
| Feature | 503A | 503B |
|---|---|---|
| Regulation | State Board of Pharmacy | FDA-registered |
| Prescription | Required (patient-specific) | Can compound without patient Rx |
| Testing | Varies by state | cGMP required |
| Scale | Small batches | Larger production |
| Quality consistency | Variable | Generally higher |
I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.
A narrower follow-up, since the general answer is now clear:
What would you measure differently if you were starting again?
Certified reference materials, analytical reagents, and research-grade standards for peptide verification. Trusted by laboratories worldwide.

Regarding compounded supply compounding legality: compounding pharmacies can legally produce semaglutide and tirzepatide while these drugs remain on the FDA shortage list. If/when the shortage resolves, the legal landscape may change.
Stay informed. The FDA shortage list is updated regularly. Current status as of my last check: semaglutide partially resolved shortage, tirzepatide still in shortage. This directly impacts compounding availability.
