u/units_not_mg
Every dosing mistake I have seen came from confusing units with milligrams.

Removed the dose recommendation. You can describe what you did; you cannot tell somebody else what to take.

Nothing on this board is medical advice, and rate, target and method are questions for somebody who knows your history.

Nobody noticed for months. Then several people noticed in the same fortnight, which was strange and quite nice.

Disagreeing with this line: that is the arrangement in one nation and the question is about another.
comment on anyone else notice weekly dosing kicking in around week 33 in c/semaglutide · 171 points · 1 year ago
My stall was eleven weeks. Eleven. Then it moved again without me changing anything at all.
comment on three years of 2.4mg threads, summarised so you do not have to read them in c/semaglutide · 132 points · 1 year ago
The mental model that finally made this click for me: there are two curves, and people watch the wrong one.
The first is exposure, which is set by the dose and smoothed by a week-long half-life. It changes when you change the dose and then settles over about a month. The second is body weight, which is exposure filtered through appetite, food, water, sleep, training and the scale itself, and which moves in steps rather than a line.
Almost every "it stopped working" post is somebody watching curve two over a fortnight and drawing conclusions about curve one. If the appetite effect is still there, exposure is fine. Wait the month.

comment on [PSA] Wegovy is not what most of this community thinks it is in c/semaglutide · 55 points · 1 year ago
reflux made the first fortnight rough at each step up, then flattened out. Predictable enough that I started planning around it.
comment on why does nobody talk about reconstitution in c/reconstitution · 34 points · 1 year 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.

waist is the measurement that keeps moving during a scale stall

comment on [Meta] the goal rule is doing its job and people should stop complaining in c/progresspics · 103 points · 2 years ago
What to measure if you want to stay sane through the flat parts.
Weight, under consistent conditions, no more than weekly. Waist, monthly — it frequently keeps moving when the scale does not. And one non-scale thing a week written down: a garment, a staircase, a distance, an ordinary task that got easier.
A year of those three is a far better record than a year of daily weights, and reading the third column back is the part that actually means something. The daily number is noise dressed up as information, and it has ruined more months on this board than any plateau.
comment on [Question] how do you actually verify mg/mL in c/reconstitution · 43 points · 2 years ago
Reconstituted at 1mL when I meant to use a different volume. Caught it because the units looked wrong on the barrel. Now I write 5mg/mL on the glass before I put the cap back.

Four pharmacies, four prices, same product, same month. The spread was larger than I expected and none of them were the headline offer.

What dose and how many weeks at it before this started?

On the "everybody ends up at 2.4" claim, which comes up every few weeks.
The escalation schedule in the trials was designed to get people to a fixed study dose. Real use is not a trial. The dose that keeps your appetite quiet with side effects you can live with is the dose, and for a lot of people on this board that has been 2.4mg for a very long time.
The counter-argument, which is fair: some people genuinely do need the top of the range, and staying low out of caution costs them months. That is a conversation with someone who knows your history, not with us.
comment on three years of bacteriostatic water threads, summarised so you do not have to read them in c/reconstitution · 72 points · 2 years 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.

Yes — and the honest version is that most of the "it stopped working" posts turn out to be a normal fortnight of water weight.

That reads like a titration plan and this board cannot give you one. Somebody who actually knows your history has to.

Strongly agree on protein. It did more for my injection-site soreness than any of the things I bought to fix my injection-site soreness.
