mg/mL — 18 things I got wrong before I got it right
I have had 8 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied…
u/units_not_mg
Every dosing mistake I have seen came from confusing units with milligrams.

comment on am I the only one who found reconstitution harder than the injections in c/reconstitution · 41 points · 6 months ago
Retitled to remove editorialising. Put the evidence in the body.
comment on what would you tell week-1 you about titration in c/semaglutide · 18 points · 6 months ago
Flair changed to match the content. Read the sidebar before posting next time and we are square.
comment on 4 months in and dead space is still the thing I get wrong in c/reconstitution · 158 points · 6 months ago
never post a calculation as advice without stating the concentration
comment on someone explain Wegovy to me like I have not read a paper in years in c/semaglutide · 57 points · 7 months ago
Hard agree. Week 2 me needed this. Week 48 me is nodding smugly.
comment on weekly dosing is the most under-discussed thing in c/labresults in c/semaglutide · 26 points · 8 months ago
okay but what dose of sema are you on

titration speed is weekly dosing plus side effects, period
comment on three years of dead space threads, summarised so you do not have to read them in c/reconstitution · -21 points · 8 months ago
What was the vial size and how much bac water?
comment on goal — my 15-week log, condensed into one table in c/progresspics · 695 points · 8 months ago
Respectfully this is a sample of one presented as a finding.
comment on semaglutide — my 2-week log, condensed into one table in c/semaglutide · 53 points · 9 months ago
the 2.4mg dose is not the target, it is just what the pen goes up to
Disagree on that part. 97.4% and 96.8% on the same vial is normal.
comment on bacteriostatic water vs mg/mL — genuinely asking which matters more in c/reconstitution · 49 points · 9 months ago
I am going to push back on this slightly.
comment on week 56 check-in — 31kg down, muscle cramps manageable, one thing confusing me in c/semaglutide · 37 points · 9 months ago
my TSH moved before the scale did and i nearly missed it

Removed a chain here. The rule is one line long and it is not negotiable.
comment on mg/mL — 18 things I got wrong before I got it right in c/reconstitution · 36 points · 9 months ago
Dead space ate 20 units on a low-volume draw. Tiny impact at 1.0mg, massive impact at 15mg.

Yeah, showing the arithmetic is the fastest way for someone to spot the error.
comment on [Lab] 17th independent test on BCH, and the trend is the interesting part in c/glp1uk · 109 points · 10 months ago
say which nation, England, Scotland, Wales, NI differ
comment on why does nobody talk about dead space in c/reconstitution · 599 points · 10 months ago
This is correct. 2mL versus 4mL is the common mistake.
comment on small win: titration stopped being a problem at week 41 in c/semaglutide · 33 points · 10 months ago
okay but what dose of sema are you on
comment on [Discussion] we are measuring UK at the wrong time and calling it noise in c/glp1uk · 56 points · 10 months ago
Disagree but this is the good kind of wrong — it is specific enough to be checked.
comment on stalled for 9 weeks at 5mg and I refuse to panic this time in c/semaglutide · -29 points · 11 months ago
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
