[Lab] split one vial across Janoshik and Medutest — 99.2% and 98.9%

Lab Well Actually ×2 Slow Clap ×3

Right: split one vial across Janoshik and Medutest — 99.2% and 98.9%. I paid for this one myself, nobody sent me anything, and the receipts are in the comments.

Hard numbers: 99.2% and 98.9%. Anything softer than that is flagged as an impression.

What the glucagon arm is doing, as best anyone can say from public data.

GLP-1 and GIP agonism cover appetite and insulin secretion in ways that are now reasonably well characterised. Glucagon receptor agonism is the third leg and it is associated with increased energy expenditure and with effects on hepatic fat.

Mechanistically that is why this compound reads as a different proposition rather than a stronger version of a dual agonist. Clinically, the size and durability of that difference in humans is precisely what is not yet established, and anyone telling you otherwise is filling a gap with confidence.

The standing caveat, written out properly because it keeps getting compressed into a footnote.

Nothing containing this compound is approved by any regulator. Research-use-only material is not approved for human use. That is not a legal formality on this board — it is why there is so little independent data, why the escalation schedules people post are invented, and why nobody here can answer a dosing question.

What this board can usefully do is read the published trials carefully, log independent purity results, and be honest about how thin the evidence base is. Everything else belongs somewhere with a clinician in it.

I will update this if the picture changes rather than quietly leaving it up.

Removed the escalation schedule. There is no published protocol for members to follow and inventing one here is exactly what this board does not do.

Glucagon receptor agonism is associated with increased energy expenditure and with hepatic effects. That is a mechanistic story with strong preclinical support and limited phase 2 human data.

a lot of the confident posting here is extrapolation

What do you think the glucagon component is adding, specifically?

wait for phase 3 before you argue about rankings

The early fullness profile felt different rather than worse. Hard to describe and impossible to quantify, so take it as an impression.

Yes — the glucagon arm is what makes it a different proposition rather than a stronger version of the others.

This. The phase 2 result was genuinely large and it was also 48 weeks in a few hundred people.

Right, and it bears repeating that nothing here is approved anywhere and research material is not for human use.

the energy-expenditure story is mechanistically interesting and clinically unproven

Kept a log specifically because there is so little published. It is one person and it is not data.

Small fix — three receptors, not two. GLP-1, GIP and glucagon, and the third one is the reason this compound gets its own board.

About c/retatrutide

Retatrutide: GIP/GLP-1/glucagon triple agonism, the TRIUMPH programme, and the fact that most people discussing it are handling research-grade material with no human-use approval anywhere. Dose-response, heart-rate signal, and the unusually steep phase-2 weight curves get argued about here weekly.

c/retatrutide rules
  1. Retatrutide is not approved anywhere for human use. Posts must not read as usage instructions.
  2. Phase 2 numbers are not maintenance numbers. Cite the trial and the dose arm.
  3. Heart-rate and dose-escalation reports need actual measurements, not impressions.
  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.
