nope, redo it

Highlights from this day
- noct.titrate — what do you do with the last 40 units when you cant draw them cleanly 22:11
- reed_reta — gross powder mass is not net peptide. water and counterion are in that number 22:27
- bengaluru_bac — do you let it come to room temp before drawing or draw it cold 23:33
- noct.titrate — you can absolutely just always use 2ml, and honestly most of us should, i think 23:44
one unit is 0.01ml
anyone worked out a recon volume that puts 2.5mg on a round unit mark
what do you do with the last 40 units when you cant draw them cleanly

does benzyl alcohol matter if im finishing the vial in one go

i use bac water even for a single-use vial because it stings less, which is not the reason it exists
✅1
unrelated but 10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100
bac water or sterile water for something im going into weekly for 9 weeks
pick the volume so your dose is a whole number of units. thats the entire trick

if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
thats 5mg/ml
while im here my 10mg vial weighed 11.4g on the jewellery scale, is that wrong
round numbers

a slightly collapsed cake is cosmetic. a puddle in the bottom is not
🤝2📈1
is a slightly cloudy solution ever ok or is that always a bin it
yep 10 units
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
[edited]Reminder for reed_reta: dose day is today. Set 6 days ago.
if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space
a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with
Recon calculator: 30mg in 5ml = 5mg/ml.
update on the earlier thing 5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
the powder is stuck to the stopper, do i care
does it matter if i inject the bac water straight at the powder
[edited]label the vial
i write the mg/ml on the vial with a sharpie the moment i reconstitute it
pick the volume so your dose is a whole number of units. thats the entire trick
for the archive one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that
label the date too. you will not remember which vial is which by week 30
15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it
bac water
do not add more bac water to an already reconstituted vial, you have lost track of the concentration
can i add more bac water later to a vial ive already reconstituted
coming back to this anyone else find the 10mg vials harder to get fully dissolved than the small ones
give it 2 minutes at room temperature before you decide it has not dissolved, i could be wrong
i have never once regretted using a rounder number and a slightly bigger volume
dead space
coming back after 6 months, has the pinned recon volume advice changed

do i swirl for a specific length of time or just until its clear
it foamed. is it ruined
do you let it come to room temp before drawing or draw it cold

is there any reason not to just always use 2ml
thats fine
update from 20 months ago: switched to a single concentration and have not miscalculated since
check your maths
you can absolutely just always use 2ml, and honestly most of us should, i think
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/mlunrelated but is it normal for the cake to look slightly collapsed on one side
