am I the only one who found area percent harder than the injections
Right, the area percent question again, but with numbers this time.
I have 7 data points over 24 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.
The thing I would flag for anyone new: the effect I am describing showed up at week 85, not week 39. People give up long before the interesting part.
Interested in whether this matches other people's logs or whether I am an outlier.
best — the order this archive was captured in
The COA I was holding said 96.8% area and I thought it was trash. Turns out the method was solid and the impurity profile was clean.
area% is not mass%, and here is exactly why it matters
purity and net content are two different numbers, same vial
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
Cosigning. The batch number is load-bearing information.
the counterion is part of the mass you paid for
Four months on the site and I was confusing area% and mass% in every post I made. One explainer thread and it clicked.
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
purity and net content are two different numbers, same vial
the related substances line is where the story is
This is the correct framing. The COA structure matters as much as the number.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
