[Lab] SGN survo — VendorInvestigate came back 93.7% against a claimed 94.2%

Regulatory

I have had 7 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 36 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 97.9% against a claimed 98.0%, 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.

This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.

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

u/clara_danquah7 points·6 months ago

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

This is correct.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

shortage list status is shortage list, check the actual list

state board rules differ, say which state

That is net peptide content, not purity. Different number, different meaning.

You have restated the marketing copy. What is the actual substance here.

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

u/lipid_panel_larrybloodwork3 points·6 months ago

Asked 19 compounders about API source. One told me, one dodged, one said they cannot say. The answer is the signal.

What is the actual shortage list status right now?

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.
