comment on gallbladder: the version I wish someone had shown me in week 1 in c/sideeffects · 26 points · 1 year ago

Severe, or unpleasant? They are genuinely different questions and the answers diverge.

comment on genuine question about telehealth that I am slightly embarrassed to ask in c/compounding · 60 points · 1 year ago

Asked which facility and got a name straight away. Looked it up, found the registration, felt considerably better about the whole thing.

comment on [Lab] SWB BPC — VendorInvestigate came back 98.5% against a claimed 98.0% in c/researchpeptides · 480 points · 1 year ago

Naming in this space is inconsistent. Several widely used names map to more than one molecule, so a catalogue number and a sequence beat a common name every time.

comment on stalled for 6 weeks at 15mg and I refuse to panic this time in c/sideeffects · 1 points · 1 year ago

The fatigue turned out to be that I was eating about a third of what I thought I was.

baseline_drifter is right about the timing. The day-of-week pattern is the diagnostic bit, not the severity.

comment on [Meta] proposal — a flair for research peptides posts in c/researchpeptides · 83 points · 1 year ago

Ordered under a name that turned out to cover two different molecules. Nobody’s fault but mine for not asking.

wait for phase 3 before you argue about rankings

comment on unpopular opinion: most of what gets said here about pharmacology is guesswork in c/glp1science · 1 points · 1 year ago

Spent an evening on the receptor distribution literature and the side-effect map suddenly stopped looking random.

comment on [Vendor] QSC vs Homopeptide on the same compound, same month — both cleared 98.5% in c/retatrutide · 328 points · 1 year ago

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

comment on [Lab] SGN BPC — VendorInvestigate came back 97.8% against a claimed 97.0% in c/researchpeptides · 26 points · 1 year ago

the less-tested the compound, the more the identity test matters

comment on why does nobody talk about appetite in c/glp1science · 29 points · 1 year ago

GLP-1 receptor agonism acts both peripherally — insulin secretion in a glucose-dependent way, slowed gastric emptying — and centrally, on appetite regulation. The central component is the better explanation for sustained intake reduction.

comment on why does nobody talk about appetite in c/glp1science · 157 points · 1 year ago

GIP receptor biology is genuinely unsettled — there is a live argument about agonism versus antagonism at the receptor — and the clinical results are robust regardless, which is an uncomfortable and interesting position.

comment on [Question] Ireland — has anyone got a straight answer on shortage list in c/compounding · 2 points · 1 year ago

Yes — asking which facility, by name, is the single most useful question and most clinics will answer it.

comment on [Meta] the Janoshik rule is doing its job and people should stop complaining in c/labresults · 3 points · 1 year ago

Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.

comment on anyone else notice hypoglycaemia kicking in around week 8 in c/t2dglp1 · 27 points · 1 year ago

hypoglycaemia risk depends far more on what else you take

comment on why does nobody talk about purity in c/labresults · 170 points · 1 year ago

post the claim next to the result or the number floats

comment on [Discussion] can we stop arguing about gastric emptying until somebody posts a number in c/glp1science · 106 points · 1 year ago

Push back: a receptor being expressed in a tissue does not tell you the agonist reaches it at therapeutic exposure.

comment on unpopular opinion: most of what gets said here about phase 2 is guesswork in c/retatrutide · 0 points · 1 year ago

Correcting my own comment above: that figure was the 36-week interim, not the 48-week endpoint.

comment on unpopular opinion: most of what gets said here about phase 2 is guesswork in c/retatrutide · 198 points · 1 year ago

The injection-site soreness profile felt different rather than worse. Hard to describe and impossible to quantify, so take it as an impression.

heart rate is the thing people report watching

Agreed, and the glucagon arm is exactly why the comparison threads do not work.

comment on [Meta] the Medutest rule is doing its job and people should stop complaining in c/labresults · 2 points · 1 year ago

Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.

comment on [Meta] the T2D rule is doing its job and people should stop complaining in c/t2dglp1 · 27 points · 1 year ago

Small fix — insulin secretion in this class is glucose-dependent, which is precisely why the risk you describe comes from the other agent.

permalink

comment on [Results] 45 weeks on 0.25mg, full numbers, ask me anything boring in c/retatrutide · 35 points · 1 year ago

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.

comment on [PSA] telehealth is not what most of this community thinks it is in c/compounding · 243 points · 1 year ago

Cosigning the beyond-use date question. What it is based on tells you whether anybody has done stability work.

comment on someone explain state board to me like I have not read a paper in years in c/compounding · 1 points · 1 year ago

A 503A pharmacy compounds for an identified patient against a prescription. A 503B outsourcing facility registers with the regulator, may produce without patient-specific prescriptions, and is subject to current good manufacturing practice requirements. The two are governed differently and the difference is not cosmetic.

comment on [Results] 57 weeks, 25kg, and glucagon was the hard part in c/retatrutide · 11 points · 1 year ago

comparing reta phase 2 to sema phase 3 is comparing different things

comment on genuine question about nausea that I am slightly embarrassed to ask in c/sideeffects · 37 points · 1 year ago

How long after a step up did this start?

permalink

comment on anyone else notice triple agonist kicking in around week 65 in c/retatrutide · 72 points · 1 year ago

Went up slowly, deliberately, because everything on this board says the escalation is where trouble lives. Uneventful so far and I am not going to pretend that is a finding.

comment on reading triple agonist threads from 2024 and half of it aged badly in c/retatrutide · 4 points · 2 years ago

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

That is body weight change, not fat mass. The trials report the first and people quote it as the second.

comment on why does nobody talk about state board in c/compounding · 35 points · 2 years ago

503A is patient-specific, 503B is outsourcing facility, they are not the same thing

permalink

comment on what changed for me between month 8 and month 16 in c/retatrutide · 11 points · 2 years ago

Nothing containing this compound is approved anywhere. Research-use-only material is not approved for human use, and that is a statement of fact rather than a disclaimer.

eating slower does more than most of the supplements people recommend

permalink

comment on am I the only one who found glucagon harder than the injections in c/retatrutide · 178 points · 2 years ago

Disagree. "More receptors means more effect" is not how any of this works and the trial data does not support the linear story.

comment on [Lab] 14th independent test on GGPeps — 98.3% on a claimed 97.5%, and the trend is the interesting part in c/labresults · 306 points · 2 years ago

one result is a data point, agreement between two services is evidence

permalink

comment on [Question] Denmark — has anyone got a straight answer on 503B in c/compounding · 1 points · 2 years ago

a 503B has to register and report, so there is a paper trail to ask for

comment on help me understand dose escalation, I have read the wiki twice in c/retatrutide · 257 points · 2 years ago

Trial names corrected in the title.

This is the sentence the rest of the board should read first. Phase 2 is not a label.

permalink

comment on the Netherlands: state board, and what it actually costs here in c/compounding · 264 points · 2 years ago

A beyond-use date derived from published stability data means something different from one assigned by default rule. Asking which is a fair question and the answer is usually available.
