New independent result logged — TFC, lot A-2418, purity 98.6% (VendorInvestigate).
is it normal for the cake to look slightly collapsed on one side
yep 10 units
is there any reason not to just always use 2ml
do not add more bac water to an already reconstituted vial, you have lost track of the concentration
the jewellery scale is a good habit but calibrate it, they drift badly
foam is bad
it foamed. is it ruined

lyophilised powder is far more robust than people think. it is the solution that is fragile
read it at eye level
aim the diluent at the glass wall, not at the powder. it goes in gentler, your mileage will differ
one unit is 0.01ml
follow up gross powder mass is not net peptide. water and counterion are in that number
clear or bin it
i write the mg/ml on the vial with a sharpie the moment i reconstitute it
label the vial
temperature of the diluent does not matter. how fast you push it in does
weighing the vial before you reconstitute is the only way to catch an underfill
not sterile water
follow up what do you do with the last 20 units when you cant draw them cleanly
Reminder for secretagogue_sy: dose day is today. Set 3 days ago.
while im here how do you all measure a half unit, or do you just not
dead space
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all

5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose
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 = 50uround numbers
