comment on [Regulatory] 503A vs 503B in one paragraph, because everyone conflates them in c/compounding · 5 points · 1 days ago

the label on a compounded vial is a legal document, read it

comment on asked my compounder where the API comes from. long silence. in c/compounding · 14 points · 2 days ago

Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.

comment on [Training] three full-body sessions a week through the whole cut in c/glp1muscle · 0 points · 3 days 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 [Question] does anyone get a COA from their compounding pharmacy in c/compounding · 15 points · 14 days 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.

Correction: those scans are from different machines, and the difference you are describing is within the measurement error.

Is the prescription from the same country as the pharmacy?

comment on how much of what we believe about FFMI actually comes from resistance training threads in c/glp1muscle · 6 points · 3 months ago

Resistance training, and at what frequency?

permalink

comment on [PSA] reimbursement is not what most of this community thinks it is in c/glp1eu · 68 points · 4 months ago

Supply notices are issued nationally. A notice in one member state does not imply availability problems in another, even for the same product.

comment on [Question] how do you actually verify resistance training in c/glp1muscle · 10 points · 4 months ago

What is protein intake actually looking like, measured rather than estimated?

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

comment on Sweden: state board, and what it actually costs here in c/compounding · 1 points · 6 months ago

Same view. If the intake asked you nothing, the intake was a formality and you should factor that in.

comment on [Discussion] we are measuring telehealth at the wrong time and calling it noise in c/compounding · 1 points · 6 months ago

Concentration on the compounded vial was different from what I had been using and I nearly did the arithmetic on autopilot.

comment on [PSA] DEXA is not what most of this community thinks it is in c/glp1muscle · 14 points · 7 months ago

Push back: strength dropping in a deficit is not the same as lean mass loss. Related, not identical.

do not compare your composition to a trial average

Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.

Agreed on potency testing of the finished preparation. That is a different question from the purity of the starting material.

if a clinic will not name the facility, that is your answer

comment on the lean mass thing finally clicked for me and I want to write it down in c/glp1muscle · 14 points · 1 year ago

Not convinced by that DEXA comparison. Different machine, different protocol, and the difference is inside the error.

comment on reading pharmacy threads from 2024 and half of it aged badly in c/glp1eu · 82 points · 1 year ago

Push back: comparing headline prices across countries without normalising pack size is comparing two different quantities.

Reimbursed or private?

Salt form matters for mass: a preparation specified as one salt and dosed as the free base gives you a different amount of peptide for the same number on the label.

What was the rate of weight change over that window?

comment on [Question] Ireland — has anyone got a straight answer on shortage list in c/compounding · 8 points · 1 year ago

That figure is the starting material purity, not the finished preparation potency. Two different tests.

comment on three years of Apotheke threads, summarised so you do not have to read them in c/glp1eu · 144 points · 1 year ago

Nothing here is medical or legal advice, and eligibility questions have national answers that a pharmacist where you live can give you in minutes.

comment on help me understand telehealth, I have read the wiki twice in c/compounding · 27 points · 1 year ago

Reminder that nothing here is medical advice and this board cannot tell you which arrangement to choose.

This is the distinction the whole board runs on. Everything else follows from it.

ask what the beyond-use date is based on

Criteria changed at plan renewal and the denial that had been immovable simply did not apply any more.

Right, and a shortage notice in one country tells you very little about the next one along.
