Highlights from this day
- step_one_sian — lyophilised powder is far more robust than people think. it is the solution that is fragile 5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose 21:43
- step_one_sian — unrelated but i keep a spare vial of bac water in the fridge purely so i never rush the maths 5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose 21:47
- step_one_sian — does it matter if i inject the bac water straight at the powder 21:51
- triple_ag_tom — update on the earlier thing i was wrong about this last year: it is fine to draw cold, it just stings more going in, from memory 22:05
- VialBot — Digest for the week of 2024-01-01 has been published. 22:23
coming back to this does benzyl alcohol matter if im finishing the vial in one go
i swirl for about thirty seconds and then leave it. never had one fail to dissolve, i have it written down somewhere

thats fine
*that should say weekly

right so do you draw up with the same pin you inject with
does it matter if i inject the bac water straight at the powder
U-100 syringe: 1 unit = 0.01 ml
10u = 0.10 ml
25u = 0.25 ml
50u = 0.50 ml
100u = 1.00 ml
mg drawn = ml drawn x mg/ml⚠️2💀10📈11
the meniscus thing is real. read it at eye level or you are guessing by a unit either way

weighing the vial before you reconstitute is the only way to catch an underfill
you can absolutely just always use 2ml, and honestly most of us should
check your maths
if i add 2.5ml to a 5mg vial what concentration am i actually at
5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose
coming back after 16 months, has the pinned recon volume advice changed
Digest for the week of 2024-01-01 has been published.
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way, thats one data point
