Highlights from this day
- VialBot — Recon calculator: 2mg in 2.5ml = 2.5mg/ml. 20:15
- kev_measures — is it normal for the cake to look slightly collapsed on one side i swirl for about thirty seconds and then leave it. never had one fail to dissolve 21:05
- kev_measures — while im here i have never once regretted using a rounder number and a slightly bigger volume 21:26
whats the smallest volume you would trust yourself to measure on a u100

does benzyl alcohol matter if im finishing the vial in one go
i was wrong about this last year: it is fine to draw cold, it just stings more going in
weigh it first
i keep a spare vial of bac water in the fridge purely so i never rush the maths
write the date on

do you let it come to room temp before drawing or draw it cold
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way
give it 5 minutes at room temperature before you decide it has not dissolved
my vial pulled the water in on its own, is that the vacuum or did i do something

my rule is one concentration for everything so i never have to think about it at 7am
my 10mg vial weighed 11.4g on the jewellery scale, is that wrong
10mg vial
+ 1.0ml -> 10.0 mg/ml 0.5mg = 5u 1mg = 10u
+ 2.0ml -> 5.0 mg/ml 0.5mg = 10u 1mg = 20u
+ 2.5ml -> 4.0 mg/ml 0.5mg = 12.5u (dont)
+ 5.0ml -> 2.0 mg/ml 0.5mg = 25u 1mg = 50uis it normal for the cake to look slightly collapsed on one side
i swirl for about thirty seconds and then leave it. never had one fail to dissolve

the powder is stuck to the stopper, do i care
10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100
😂6🔥10✅1
15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it, for what its worth
i write the mg/ml on the vial with a sharpie the moment i reconstitute it
the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol

coming back after 3 months, has the pinned recon volume advice changed
while im here i have never once regretted using a rounder number and a slightly bigger volume

nope, redo it
while im here im getting bubbles in the barrel every single time, what am i doing wrong
genuine question i swirl for about thirty seconds and then leave it. never had one fail to dissolve
i use bac water even for a single-use vial because it stings less, which is not the reason it exists
the jewellery scale is a good habit but calibrate it, they drift badly
swirl dont shake
follow up a slightly collapsed cake is cosmetic. a puddle in the bottom is not
label the date too. you will not remember which vial is which by week 20
