three years of dead space threads, summarised so you do not have to read them
I have had 15 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 by about 8 days on nominally the same lane, which matters more in summer than in February.
The independent number came back 93.7% against a claimed 98.6%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.
Batch number is in the comments. Ask if you want the method.
best — the order this archive was captured in
Cosigning. The concentration on the vial in marker is load-bearing.
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
Rodent data is rodent data.
Yes, exactly this, and it is the bit that took me 69 weeks to accept.
show your working or it is unhelpful
the concentration on the vial in marker is the most important step
Sceptical. If this were true we would see it reflected in the data and we do not.
dead space is real and the syringe matters
Spent 8 weeks confused about concentration math until someone showed me the table. 20mg, 2mL, concentration is 20/2.
the concentration on the vial in marker is the most important step
stopper coring on the 5th draw because you keep using the same entry point. rotate.
5mg vial, 2mL water, concentration is 5/2 — write it on the vial afterwards
Crossposting this to c/intlshipping because the people who need it are not reading this community.
What was the vial size and how much bac water?
bacteriostatic and sterile water are not interchangeable, do not use them that way
the concentration on the vial in marker is the most important step
never post a calculation as advice without stating the concentration
Yeah, showing the arithmetic is the fastest way for someone to spot the error.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
dosing errors come from people reconstituting two vials differently and forgetting which is which
