the compounding thing finally clicked for me and I want to write it down

Questionbranch of 6 comments

Posting this as a discussion rather than a claim: the compounding thing finally clicked for me and I want to write it down. Why "compounded" is not "generic", written out because the confusion is constant. A generic is an approved product demonstrated to be bioequivalent to a reference. A compounded preparation is…

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.
