[Discussion] the API source advice in here is 3 years out of date

Discussion Receipts ×6

the API source advice in here is 3 years out of date, and I am aware this is a minority view on this board.

The relevant figures are 3 years, and they come from the same log I have kept the whole time.

Salt form matters for mass: a preparation specified as one salt and dosed as the free base gives you a different amount of peptide for the same number on the label.

Potency and sterility testing on the finished preparation are separate from any certificate covering the starting material. Ask which you are being shown.

That is everything I have. The rest is opinion and I have tried to keep it out.

Compounded preparations are not approved products and carry no bioequivalence claim. That is a statement about regulatory category, not about quality.

discount_math_dm is right about the concentration trap. It breaks arithmetic that has been reliable for months.

the pharmacy and the prescriber are two separate questions

Agreed on potency testing of the finished preparation. That is a different question from the purity of the starting material.

Nothing in this thread is medical advice, and the choice between arrangements is one for you and a prescriber who knows your history.

a telehealth intake that asks nothing has told you what it is

Who is the prescriber, and are they the same organisation as the pharmacy?

Who is the prescriber, and are they the same organisation as the pharmacy?

Disagreeing with this bit: registration is not equivalence, and the two get run together constantly.

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.
