comment on [PBS] listing status and what it actually does to out-of-pocket in c/glp1aus · 3 points · 2 days ago

Is this about registration or about subsidy?

sten_bhattacharya is right that the two countries are separate systems and the answers diverge.

Subsidy criteria and authority requirements are published. For eligibility questions those documents are authoritative and this board is not.

comment on the scale "stalled" for two months but my DEXA says otherwise, recomp is a stall in disguise in c/glp1muscle · 143 points · 3 days ago

and this is the flip side of the sarcopenia risk everyone worries about with these drugs — same mechanism (appetite suppression + calorie deficit) can go either direction depending on protein and resistance training, and this table is what the good direction looks like on a scan.

comment on hair started shedding at month 4 and stopped at month 9. protein and patience. in c/sideeffects · 84 points · 3 days ago

the protein point generalises well beyond hair. under-eating protein during rapid loss costs you lean mass and you will not see that on a bathroom scale.

comment on [Discussion] resistance training changes what "stall" should even mean on the scale in c/glp1muscle · 54 points · 3 days ago

and the "losing the wrong tissue" case is the one that gets underfunded research-wise, lean mass loss risk on these drugs is a real open question and the scale alone will never flag it

Chased the last three kilos with a dose increase and got a fortnight of early fullness and no change in the number.

comment on regain: what the trials say vs what this community says in c/maintenancephase · 1 points · 1 months ago

Been at maintenance for 17 months on 1.0mg. Nothing happens. That is the whole report and it took me a while to accept it as success.

Correction: that is the registration decision, not the subsidy listing. They are made by different bodies.

Australia and New Zealand have different regulators, different funding bodies and different arrangements. An answer for one is not evidence about the other.

comment on someone explain regain to me like I have not read a paper in years in c/maintenancephase · 8 points · 3 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 lowers average exposure. That is why appetite return is often the first thing noticed.

Adding one thing — decide what maintenance looks like before you arrive at it.

That is a range, not a trend. Two weigh-ins 14 days apart cannot distinguish them.

That is a trial average in a supervised population and you are comparing your own scan to it.

Compounded supply arrangements have changed materially in recent years. Advice predating that change describes a situation that no longer applies.

What the evidence actually supports, stripped of the arguing.

Agreed — and same machine, same conditions, or the two scans are not comparable.

The two decisions that this whole board turns on, kept apart.

Registration means a product may lawfully be supplied. Subsidy listing means the public system will fund it, for a defined indication, against published criteria. They are made by different bodies on different timetables, and a product can be registered and unsubsidised for a given use for a long time.

Almost every "why can I not get this" thread here is really a question about the second decision being answered with facts about the first. Say which one you are asking about and the thread resolves in two replies.

Agreed on the error margin. Quoting a DEXA to one decimal implies a precision the method does not have.

That is a pharmacy-level stock issue rather than a national supply issue. They feel identical and are not.

On comparing yourself to composition figures from trials.

Published composition data comes from supervised populations with structured protocols, standardised scanning, and analysis populations that have been defined in advance. Your two scans at a local clinic, taken in different states of hydration, are not the same measurement.

Use your own baseline. The question worth asking is whether your own trajectory is going the way you want given what you are actually doing, and the honest answer usually requires measuring protein rather than estimating it and being truthful about training frequency. Neither of those is advice — a programme and a target are things to work out with somebody who knows your history.

Disagree with chasing the last stretch by going up. You are trading a real side-effect cost for a number you chose arbitrarily.

Agreed. Lowest effective dose is the actual maintenance question and it gets almost no airtime next to the escalation threads.
