[Discussion] API source is doing more work than we give it credit for

Discussion Well Actually ×1

Something I noticed reading old threads that I have not seen said out loud.

The advice on telehealth in this community changed substantially around the start of last year, and nobody went back and updated the older posts. So depending on which thread the search engine hands you, you get two contradictory answers with the same confidence.

I have listed what I think the current consensus is below. Correct me — that is the point of posting it.

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

Strongly agree. API source transparency matters.

Asked 2 compounders about API source. One told me, one dodged, one said they cannot say. The answer is the signal.

This is correct. The shortage list does expire and the rules change.

Mechanistically the bit that matters is 503A. It explains most of the early profile and a decent chunk of the outcome.

The telehealth + compounding combo cost 503B plus 13% markup. Not cheap but covered by insurance depending on state.

What is the actual shortage list status right now?

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

Sceptical. If this were true we would see it reflected in the data and we do not.

Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.

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

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

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.
