anyone else notice retatrutide kicking in around week 49

Question Receipts ×4 Sourced ×2

Confession thread, sort of.

I went from 12.5mg to 5mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 3 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.

So now I have injection-site soreness I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 58 reads it before doing the same thing.

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

Research use material only, no human-use approval anywhere. Posts must describe what happened, not instruct strangers.

This is correct. Triple agonism is genuinely different.

nobody should be giving this to anyone without extensive monitoring

The heart rate signal in TRIUMPH is real and concerning. Higher doses had higher mean HR changes.

The heart rate signal in TRIUMPH is real and concerning.

Disagree on that part. 97.9% and 97.6% on the same vial is normal.

Are you quoting phase 2 or is there phase 3 data now?

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

Every time this gets posted it hits the front page and every time someone has to re-explain it.

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

Adding to this: TRIUMPH is doing more work than the comment implies.

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

TRIUMPH data is phase 2, not phase 3, smaller n and shorter

TRIUMPH phase 2 showed 99.0% weight loss but the constipation profile on the highest arm was rough. Phase 2 != phase 3.

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

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.

  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.
