Canada: API source, and what it actually costs here

Discussion Clean Column ×3 Sourced ×2

The title is the argument: Canada: API source, and what it actually costs here. Here is the rest of it.

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

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

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.

Not medical advice, obviously, and nothing here is approved for human use. One person with a spreadsheet.

A beyond-use date derived from published stability data means something different from one assigned by default rule. Asking which is a fair question and the answer is usually available.

The intake asked me three questions and none of them were about my history. That told me everything I needed to know about the model.

Asked for the beyond-use date basis and got a real answer with a stability reference attached. Not universal, apparently.

Not convinced. You are comparing a compounded concentration with a branded one and assuming they match.

Yes — asking which facility, by name, is the single most useful question and most clinics will answer it.

u/lukas_vermeulen26 points·4 months ago

Same view. If the intake asked you nothing, the intake was a formality and you should factor that in.

if a clinic will not name the facility, that is your answer

do not assume the concentration matches the branded product

the shortage list is the whole legal hinge and people skip it

This is the distinction the whole board runs on. Everything else follows from it.

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

The shortage list is the legal hinge: the permissions that allow certain compounding to happen at scale are tied to a drug’s shortage status, which changes.

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

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.
