comment on mg ÷ mL, that is the whole formula, why did i find this hard in c/reconstitution · 21 points · 1 days ago

Bacteriostatic or plain sterile water?

keep the prescription and the receipt, both matter for claims

comment on [Readout] SELECT: MACE HR 0.80, and the absolute numbers people skip in c/trialwatch · 7 points · 2 days ago

That is the 68-week readout, not the 72-week one. Different trial, different duration.

comment on [Question] does needle dead space actually matter at 2.5mg doses in c/reconstitution · 23 points · 3 days ago

The arithmetic in full: concentration is mass over volume, so 30mg into 3mL gives 10mg/mL. A U-100 syringe is graduated at 100 units per millilitre, so 5mg is 5 divided by 10 millilitres, which is 50 units.

comment on [Country] ES — private receta, pharmacy stock, and the August problem in c/glp1eu · 1 points · 6 days ago

the language barrier is a real cost and nobody budgets for it

This is the split the whole board depends on. Authorisation is European; payment is national.

comment on sterile water is not bacteriostatic water and it is not close in c/reconstitution · 163 points · 6 days ago

Yes, and the dead-space point is worth repeating: it is small, it is real, and it is the same for every draw.

Did anything else change in the window you are asking about?

comment on [Win] approved after i sent them their own policy criteria back in c/insurancefights · 8 points · 9 days ago

Peer-to-peer took fifteen minutes and resolved something a written appeal had been sitting on for a month.

comment on [Log] spreadsheet gremlin, 61 tabs, here is the summary sheet in c/dosinglogs · 0 points · 14 days ago

Yes — log what happened rather than what you intended. My retrospective entries were quietly wrong every time.

comment on watch where the curves separate, not just whether they do in c/trialwatch · 17 points · 22 days ago

The press release said that; the publication says something more hedged. Worth reading both.

comment on someone explain protein to me like I have not read a paper in years in c/glp1muscle · 1 points · 27 days ago

Three scans over eighteen months, same machine, same conditions. Only the third one made the first two interpretable.

comment on genuine question about mg/mL that I am slightly embarrassed to ask in c/reconstitution · 1 points · 1 months ago

Careful — that arithmetic is wrong.

Adding one thing — put the date on the label too. Concentration plus date and you can never mix two vials up.

comment on the bacteriostatic water thing finally clicked for me and I want to write it down in c/reconstitution · 33 points · 1 months ago

Correcting myself above: I wrote the concentration the wrong way up. Mass over volume, not volume over mass.

permalink

comment on the bacteriostatic water thing finally clicked for me and I want to write it down in c/reconstitution · 78 points · 1 months ago

If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.

comment on the bacteriostatic water thing finally clicked for me and I want to write it down in c/reconstitution · 89 points · 1 months ago

The lyophilised cake displaces a small volume, so the true concentration is very slightly lower than the arithmetic suggests. It is a fraction of a percent and it is dwarfed by fill tolerance.

comment on does resistance training actually matter or is it forum lore at this point in c/glp1muscle · 20 points · 1 months ago

Hydration status and fasting state affect the lean mass estimate. Standardising both is the difference between a comparison and a coin toss.

a U-100 syringe reads 100 units to the millilitre, every time

Show the arithmetic — where did the unit figure come from?

reconstituting at a round concentration makes every later dose easy

comment on someone explain concentration to me like I have not read a paper in years in c/reconstitution · 144 points · 1 months ago

That is sterile water, not bacteriostatic. Same appearance, different product, and it matters for a multi-draw vial.

Asked QYB what volume they reconstitute to for their own stability testing and they answered in one line. Useful thing to know.

comment on [Discussion] insulin syringe is doing more work than we give it credit for in c/reconstitution · 255 points · 1 months ago

I keep a laminated card in the drawer with the arithmetic on it. Looks ridiculous. Has never once let me draw the wrong volume.

comment on [Discussion] the bacteriostatic water advice in here is 3 years out of date in c/reconstitution · 21 points · 1 months ago

What concentration did you actually reconstitute at, rather than what did you intend to?

comment on normal is the most under-discussed thing on this board in c/newbiequestions · 57 points · 1 months ago

This. Ask the basic question; the answers are what make the board searchable for the next person.

comment on [Discussion] the bacteriostatic water advice in here is 3 years out of date in c/reconstitution · 44 points · 1 months ago

Adding more water does not change how much peptide is in the vial. It changes the concentration, which changes the volume you draw for the same amount. That is the entire relationship.

Wrote the date on the vial as well as the concentration after losing track of which one was opened first.

comment on [Meta] the units rule is doing its job and people should stop complaining in c/reconstitution · 10 points · 2 months ago

Are you accounting for the powder volume, or is that where the confusion is?

permalink

comment on [Meta] the units rule is doing its job and people should stop complaining in c/reconstitution · -13 points · 2 months ago

The dead space question sent me down a rabbit hole for a week. It is a fraction of a unit and it is the same every draw.

What does the wiki page on this say — genuinely asking, not deflecting?

protein intake gets harder exactly when appetite drops

That only works if the fill weight is exactly the label weight, and it usually is not exactly anything.

lean mass loss during weight loss is expected, the question is how much

permalink

comment on [Discussion] can we stop arguing about copay until somebody posts a number in c/insurancefights · 13 points · 2 months ago

Internal appeals are decided by the plan. External review is decided by an independent body and, where it applies, its determination is binding. They are separate mechanisms and the second is chronically underused.

pack sizes differ, so per-month comparisons need care

Wrote the concentration into the log as well as on the vial. Have referred back to it more than once.

comment on [Meta] proposal — a flair for prescription posts in c/glp1eu · 1 points · 3 months ago

Correction: that is the authorisation position, and the question was about reimbursement. Different bodies, different answers.

Correction: that is the oral peptide product, which is a different thing entirely. This one is a small molecule.

Small fix — that is a reconstructed entry rather than a contemporaneous one, and the post presents it as the latter.

permalink

comment on SELECT: what the trials say vs what this community says in c/trialwatch · -15 points · 3 months ago

Cardiovascular outcome trials are powered for events, not for weight, and are typically run in a different population with different inclusion criteria. Reading a weight number out of one is reading a secondary endpoint.

What has been documented as tried, and for how long?
