Vendor communication red flags for compounded supply:
- Won't provide COA before purchase — walk away
- Claims "100% pure" without analytical data — unrealistic
- No physical address or phone number — accountability matters
- Pushes you to buy more than you need — pressure tactics
- Won't answer questions about their compounding process — transparency is key
- Payment only via crypto or wire transfer — legitimate pharmacies accept cards
A legitimate compounding pharmacy operates like a healthcare business, not a gray market dealer.
A narrower follow-up, since the general answer is now clear:
What actually distinguishes 503A from 503B, in terms of what each may make and from what starting material?

Price comparison for compounded supply across sources I've used:
| Source | Monthly Cost | Type | Purity Verified |
|---|---|---|---|
| Brand (Ozempic) | $1014 | FDA-approved | N/A (pharma) |
| 503B Compounding | $144 | cGMP compounded | Yes (in-house) |
| 503A Compounding | $124 | Patient-specific | Varies |
| Research peptide | $54 | 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.

The bulks-list asymmetry was the piece I had missed entirely. It explains why one of my two pharmacies is still arguing it can supply and the other simply stopped.

Agreed, and the enforcement dates were staggered by category — 503A first, 503B a few weeks later — because outsourcing facilities have manufactured inventory and clinic contracts to unwind while a 503A makes to order.
