[Discussion] the 503A advice in here is 16 years out of date

Discussion Cold Box ×4 Well Actually ×2

I have had 3 orders now and I keep a table, so here is the honest summary rather than a vibe.

Material has been consistent. Communication has not. Shipping has varied by about 30 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 99.0% against a claimed 99.1%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.

Batch number is in the comments. Ask if you want the method.

Not convinced. The evidence does not support that reading.

telehealth prescriber models exist, pricing differs by state

API source questions are on-topic and compounders dodging them is newsworthy

shortage list status is shortage list, check the actual list

Yes, exactly this, and it is the bit that took me 94 weeks to accept.

regulatory claims need a citation to the actual rule, not interpretation

Strongly agree. API source transparency matters.

the 503A/503B distinction is load-bearing, do not blur it

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

Slight fix: the number was 97.6, not 97.9. Decimal point, but a fairly consequential one.

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.
