comment on [Discussion] bacteriostatic water is doing more work than we give it credit for in c/reconstitution · 1 points · 6 months ago

Bacteriostatic water contains benzyl alcohol as a preservative, which is what makes repeated entry into the same vial reasonable. Plain sterile water has no preservative.

Disagree with the "more water is safer" framing. It is not safer, it is just a different number to divide by.

comment on how much of what we believe about formulary actually comes from private plan threads in c/glp1canada · 2 points · 6 months ago

Correction: that is regulatory approval, not coverage. They are separate decisions by separate bodies.

comment on tried week one for 18 weeks. here is what happened. in c/newbiequestions · 0 points · 6 months ago

the starting dose is not meant to be the dose that works

Adding the one habit worth starting today: write the concentration on the vial.

Agreed on the swirl. There is no reason to shake it and a good reason not to.

How long between the two A1c measurements?

Kept fingersticks alongside the sensor for two weeks to sanity-check it. Worth doing once.

comment on [Discussion] the shortage list advice in here is 3 years out of date in c/compounding · -16 points · 8 months ago

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

comment on Ireland: Canada, and what it actually costs here in c/glp1canada · 7 points · 8 months ago

Those criteria were revised at renewal, so the version quoted upthread is out of date.

comment on [Discussion] the normal advice in here is 2 years out of date in c/newbiequestions · 33 points · 8 months ago

Correction: the starting dose is a tolerance step rather than a treatment dose. The distinction is the answer to the question above.

comment on someone explain goal to me like I have not read a paper in years in c/progresspics · 411 points · 8 months ago

Not convinced comparison helps here. The people posting the fastest results are the tail of a distribution, not the middle.

comment on mg/mL is the most under-discussed thing on this board in c/reconstitution · 227 points · 10 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 how much of what we believe about 503B actually comes from compounding threads in c/compounding · 9 points · 10 months ago

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

permalink

comment on [Question] how do you actually verify units in c/reconstitution · 256 points · 10 months ago

10mg into 1mL is 10mg/mL, and 1.5mg of that is 15 units

comment on [Discussion] the dead space advice in here is 3 years out of date in c/reconstitution · 26 points · 10 months ago

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

comment on [Question] beginner — what am I missing here in c/newbiequestions · 65 points · 11 months ago

Appetite change and weight change are different measurements on different timescales. The first is usually noticed first and the second lags it.

comment on [Meta] proposal — a flair for state board posts in c/compounding · 50 points · 11 months ago

The shortage list is the legal hinge: the permissions that allow certain compounding to happen at scale are tied to a drug’s shortage status, which ch

Disagreeing with this bit: registration is not equivalence, and the two get run together constantly.

comment on [Question] how do you actually verify bacteriostatic water in c/reconstitution · 44 points · 1 year ago

Cosigning the round-number approach. Reconstituting to something awkward is how you end up drawing 27.5 units at six in the morning.

permalink

comment on the dead space question that gets asked weekly, answered properly in c/reconstitution · 17 points · 1 year ago

Not quite. Bacteriostatic and sterile water are not interchangeable for a multi-draw vial, and the difference is the preservative.

comment on does compounding actually matter or is it forum lore at this point in c/compounding · 1 points · 1 year ago

Small fix — 503B facilities register with the regulator; 503A pharmacies are licensed by the state board. Different mechanisms.

comment on [Lab] 10th independent test on GL Biochem — 99.4% on a claimed 99.0%, and the trend is the interesting part in c/researchpeptides · 16 points · 1 year ago

Bought small on anything without a testing history here. That rule has never once cost me anything.

Did you write the concentration on the vial?

comment on small win: glycaemic control stopped being a problem at week 17 in c/t2dglp1 · 41 points · 1 year ago

Not convinced. Hypoglycaemia risk from this class alone is low; the risk you are describing comes from the combination.

goal weights chosen at week one are usually guesses

comment on [Vendor] FGP order #12 — Germany, 4 days, no drama, receipts inside in c/cryptopay · 1 points · 1 year ago

Yes — gas is the network’s, not the supplier’s, and conflating them produces a lot of unfair complaints.

This is the check that prevents the only genuinely unrecoverable mistake in this thread.

comment on what changed for me between month 11 and month 16 in c/newbiequestions · 24 points · 1 year ago

Week 7 for me was completely flat and I was convinced something was wrong. It was not. Month two was where everything happened.
