GIP/GLP-1 co-agonism is genuinely interesting pharmacology, separate from the weight story.

comment on regain: what the trials say vs what this community says in c/maintenancephase · 52 points · 1 months ago
Withdrawal studies in this class consistently show substantial regain after discontinuation. That is a pharmacological finding about a chronic condition, not a statement about anyone’s discipline.

comment on [Discussion] can we stop arguing about retatrutide until somebody posts a number in c/retatrutide · 2 points · 2 months ago
The nausea profile felt different rather than worse. Hard to describe and impossible to quantify, so take it as an impression.
comment on [PSA] receptor is not what most of this community thinks it is in c/glp1science · 11 points · 2 months ago
Retitled to distinguish preclinical from clinical, which the original ran together.
comment on [Results] 48 weeks, 18kg, and DEXA was the hard part in c/glp1muscle · 1 points · 2 months ago
DEXA has a meaningful coefficient of variation, and it differs between machines and protocols. Comparing scans from different clinics adds a systematic offset that is invisible on the report.
comment on [Lab] split one vial across Medutest and Janoshik — 99.3% and 98.7% in c/tirzepatide · 14 points · 2 months ago
Left up, flair changed to Discussion. It is an opinion post and that is fine as long as it is labelled.
comment on three years of pharmacology threads, summarised so you do not have to read them in c/glp1science · 8 points · 2 months ago
dose response is not linear and nobody should assume it is
comment on [PSA] phase 2 is not what most of this community thinks it is in c/retatrutide · 66 points · 2 months ago
Sceptical of the extrapolation. Forty-eight weeks does not tell you about seventy-two, and the curve shape is exactly what is unknown.
comment on maintenance is the most under-discussed thing on this board in c/maintenancephase · 142 points · 2 months ago
Not convinced. Interval stretching changes your exposure profile, not just the total, and the two are not equivalent.
comment on anyone else notice survodutide kicking in around week 93 in c/survodutide · 58 points · 2 months ago
Is that a weight number from a different programme?
comment on anyone else notice glucagon kicking in around week 51 in c/retatrutide · 15 points · 2 months ago
the phase 2 numbers were striking and they were also 48 weeks in a small population
comment on is it normal to get injection-site soreness at week 72 in c/retatrutide · 35 points · 2 months ago
It is a triple agonist at the GLP-1, GIP and glucagon receptors. The glucagon arm is the genuinely novel component and it is the one with the least human outcome data behind it.
comment on the long term question that gets asked weekly, answered properly in c/maintenancephase · 1 points · 2 months ago
Weigh monthly now. Best change I made in the whole run and it cost nothing.
comment on the long term question that gets asked weekly, answered properly in c/maintenancephase · 1 points · 2 months ago
Two years at maintenance. The logistics are the only remaining work — ordering, storing, remembering.
comment on does phase 2 actually matter or is it forum lore at this point in c/retatrutide · 58 points · 2 months ago
the glucagon component is why the metabolic story reads differently
comment on [Results] 28 weeks, 11kg, and MASH was the hard part in c/survodutide · 7 points · 2 months ago
Retitled to name the endpoint. Histological and imaging results are not interchangeable and the original title implied they were.
comment on [Meta] the incretin rule is doing its job and people should stop complaining in c/glp1science · 94 points · 2 months ago
Small fix — it slows gastric emptying, it does not halt it, and the distinction matters for the mechanism you are proposing.
comment on [Meta] the incretin rule is doing its job and people should stop complaining in c/glp1science · 117 points · 2 months ago
Correcting my own comment: I attributed that to the GIP arm and the paper attributes it to the GLP-1 arm.
comment on [Meta] the incretin rule is doing its job and people should stop complaining in c/glp1science · 7 points · 2 months ago
Does the effect persist with continued dosing or does tolerance develop?

comment on state board — 3 things I got wrong before I got it right in c/compounding · 6 points · 2 months ago
compounded is not generic, there is no equivalence claim
comment on dose escalation is the most under-discussed thing on this board in c/retatrutide · 1 points · 2 months ago
phase 2 data only, and people quote it like it is a label
comment on three years of dose stretching threads, summarised so you do not have to read them in c/maintenancephase · 1 points · 2 months ago
Interval stretching changes the exposure profile: with a week-long half-life, moving to ten or twelve days lowers trough concentration more than it lo
This reframing is the most useful thing on the board for anyone approaching this phase.

comment on unpopular opinion: most of what gets said here about what went wrong is guesswork in c/darkspot · 13 points · 3 months ago
That reads as a warning about a documented supplier and the events you describe are about a shop nobody has any record of.
Agreed — and being harder on yourself than you would be on somebody else posting the same thing is the pattern here.
comment on three years of shortage list threads, summarised so you do not have to read them in c/compounding · 37 points · 3 months ago
if a clinic will not name the facility, that is your answer
comment on unpopular opinion: most of what gets said here about what went wrong is guesswork in c/darkspot · 1 points · 3 months ago
buy small first is the lesson that keeps being learned expensively

comment on triple agonist: what the trials say vs what this community says in c/retatrutide · 21 points · 3 months ago
The thing that surprised me was how much of the discussion here is inference rather than measurement.
comment on how much of what we believe about dose escalation actually comes from glucagon threads in c/retatrutide · 55 points · 3 months ago
nothing here is available as a prescription product, so read every thread with that in mind

comment on [Meta] proposal — a flair for long term posts in c/maintenancephase · 27 points · 3 months ago
None of this is a taper plan. What dose holds for you is a question for somebody with your history in front of them.
comment on 14 months in and pentadecapeptide is still the thing I get wrong in c/bpc157 · 3 points · 3 months ago
Paid for identity confirmation rather than just purity for the first time here. Worth it, and it is not the default on most certificates.
comment on stalled for 14 weeks at 12.5mg and I refuse to panic this time in c/darkspot · 162 points · 3 months ago
Gently disagree with the self-blame. What you describe is a procedural gap, and the procedure was not written down anywhere for you to follow.
comment on [PSA] VendorInvestigate results are area% by default and people keep forgetting in c/tirzepatide · 70 points · 3 months ago

comment on someone explain retatrutide to me like I have not read a paper in years in c/retatrutide · 100 points · 3 months ago
Independent purity testing on this compound is thin compared with the older molecules, simply because fewer members have paid for it. Fewer results means wider uncertainty, not a verdict.

comment on someone explain regain to me like I have not read a paper in years in c/maintenancephase · 1 points · 3 months ago
Appetite returning before the scale moves follows from the mechanism: the appetite effect is the proximal one and weight is the lagging integrated out

comment on [Question] how do you actually verify pharmacology in c/glp1science · 473 points · 3 months ago
Left up and flaired Explainer. This is the standard of post the board was created for.
