my compounded vial arrived at a different concentration than last month

Discussion

Quick one. Canada here.

503A works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.

Specifics: the route I used took 16 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.

Happy to answer questions from anyone in the same jurisdiction.

Yeah, 503A and 503B are different regulatory animals.

Did they tell you their API source or dodge the question?

The 503A pharmacy I used lost their shortage list eligibility. Same day, compounding became illegal. Rules are real.

the shortage list is temporary, it ends and compounding becomes illegal again

Are we talking 503A or 503B?

API transparency is the question that separates good compounders from sketchy ones

shortage list status is 503B, check the actual list

Flair changed to match the content. Read the sidebar before posting next time and we are square.

state board rules differ, say which state

Moved states and the compounding landscape changed completely. Different rules, different pharmacies, different costs.

About c/compounding

Compounded GLP-1s as a supply route: the 503A/503B distinction, the shortage-list mechanics that made compounding legal and then didn't, state board rules, telehealth prescriber models, and what a compounding pharmacy will and will not tell you about its API source.

c/compounding rules
  1. Regulatory claims need a citation to the actual rule, notice or docket.
  2. No pharmacy referral codes. Naming a pharmacy is fine; recruiting for it is not.
  3. API source questions are on-topic and pharmacies dodging them is newsworthy.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
