is it normal to get fatigue at week 90

Discussion Receipts ×6 Clean Column ×1 Cold Box ×1

Quick one. Canada here.

glucagon works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.

Specifics: the route I used took 20 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.

Happy to answer questions from anyone in the same jurisdiction.

Strongly agree. Heart rate escalation needs the actual data, not impressions.

What was the dosing schedule in that arm?

the glucagon component changes the side effect profile, not just the efficacy

the 5mg arm is different from 2.5mg, results do not transfer

the 1.7mg arm is different from 2.4mg, results do not transfer

Not convinced. The evidence does not support that reading.

triple agonism plus glucagon is a different physiological state than GIP/GLP-1 dual

the weight curves are unusually steep, which makes predicting individual response harder

Sceptical. If this were true we would see it reflected in the data and we do not.

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

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

phase 2 numbers are not maintenance numbers, cite the trial

Not to be pedantic but TRIUMPH and retatrutide are being used interchangeably and they are not interchangeable in real life.

the dosing is steep, the injection-site soreness reports are real, and nobody knows the human safety yet

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

triple agonism is glucagon, do not generalise

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.
