comment on mg ÷ mL, that is the whole formula, why did i find this hard in c/reconstitution · 4 points · 1 days ago

Pushback on the syringe advice: a U-100 barrel reads units of volume. Calling them "doses" is how the confusion starts.

comment on sterile water is not bacteriostatic water and it is not close in c/reconstitution · 101 points · 6 days ago

dead space in the needle hub is real and it is small

comment on cored the stopper on day 9. rotate your puncture site in c/reconstitution · 1 points · 7 days ago

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

Right — the volume you add is the only variable you control here, and the cake does not change it meaningfully.

Agreed on assay changes. A lab switching platforms between your draws is invisible unless you ask.

fatigue plus low intake is usually just low intake

comment on why does everyone say week 4 is the wall in c/semaglutide · 24 points · 12 days ago

Week 38: 13kg down, muscle cramps basically gone since about week 2, and the honest headline is that nothing dramatic happened. It was boring and it worked.

comment on sulphur burps: a taxonomy, a timeline, and my sincere apologies to my flatmate in c/sideeffects · 7 points · 15 days ago

Hair shedding after significant weight loss is a telogen effect that follows the rate of loss. It is not specific to these compounds and it resolves.

comment on [Results] 47 weeks, 8kg, and ferritin was the hard part in c/bloodwork · -5 points · 25 days ago

That comparison crosses two labs with different assays. The difference you are describing may be the method.

comment on someone explain bacteriostatic water to me like I have not read a paper in years in c/reconstitution · 3 points · 27 days 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.

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

The lyophilised cake displaces a small volume, so the true concentration is very slightly lower than the arithmetic suggests.

This is the sentence that makes the rest unnecessary. Write it on the vial and the problem is gone.

Did anything else change in that window — training, intake, hydration?

comment on [Meta] can we get an auto-reply for "what dose should i be on" in c/semaglutide · 8 points · 1 months ago

First month I lost almost nothing and nearly quit. Month two and three were where it all happened.

permalink

comment on [Meta] can we get an auto-reply for "what dose should i be on" in c/semaglutide · 9 points · 1 months ago

That figure is the 68-week trial mean, not a weekly rate. Dividing it by the weeks gives you a number that does not mean anything.

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

sema is weekly for a reason, the half-life does the smoothing

comment on the reflux question that gets asked weekly, answered properly in c/sideeffects · 120 points · 1 months ago

A symptom that begins the day after the shot and fades by day four tracks the exposure curve. One that appears at random in week 94 probably does not, and that is worth saying to a clinician rather than to us.

comment on hair loss: the version I wish someone had shown me in week 1 in c/sideeffects · 71 points · 2 months ago

Nobody warned me about constipation and I would have liked the warning. It was not dangerous, it was just deeply unpleasant and completely unexpected.

Research-use-only material is not approved for human use, so treat everything in this thread as arithmetic about solutions rather than instructions for a person.

comment on the titration question that gets asked weekly, answered properly in c/semaglutide · 6 points · 2 months ago

Yes. Week 6 is when almost everybody writes the "is it still working" post, and almost everybody is fine.

permalink

comment on my ApoB moved and I cannot work out whether constipation is why in c/sideeffects · 33 points · 2 months ago

Pushback: you changed the dose, the meal timing and the training in the same fortnight, so the attribution is guesswork.

Did the maths give you a whole number of units, or a fraction?

comment on 6 months in and sulphur burps are still the thing I get wrong in c/sideeffects · 256 points · 3 months ago

A symptom that begins the day after the shot and fades by day four tracks the exposure curve. One that appears at random in week 6 probably does not, and that is worth saying to a clinician rather than to us.

comment on constipation: the version I wish someone had shown me in week 1 in c/sideeffects · 2 points · 3 months ago

Held the dose for an extra six weeks instead of stepping. The injection-site soreness settled and I lost the same amount anyway.

comment on my hs-CRP moved and I cannot work out whether heart rate is why in c/sideeffects · 16 points · 3 months ago

Right, and the hair thing is worth repeating: it tracks the rate of loss rather than the compound, and it stops.

Kept a one-line-a-day log for two months. The pattern was obvious on paper and invisible in my head.

comment on [Discussion] can we stop arguing about titration until somebody posts a number in c/semaglutide · 101 points · 5 months ago

sulphur burps made the first fortnight rough at each step up, then flattened out. Predictable enough that I started planning around it.

permalink

comment on three years of concentration threads, summarised so you do not have to read them in c/reconstitution · -26 points · 6 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 stalled for 3 weeks at 1.7mg and I refuse to panic this time in c/bloodwork · -6 points · 6 months ago

permalink

comment on [Results] 89 weeks on 1.7mg, full numbers, ask me anything boring in c/semaglutide · 80 points · 6 months ago

The escalation schedule in the trials existed to keep people on the drug. It is a tolerability ramp, and it is why the label reads the way it does.
