Highlights from this day
- pharmac_pen — my read after three years of this: purity is mostly fine across the market and fill consistency is where suppliers differ 18:31
- mag_citrate — update on the earlier thing quantity testing is usually a separate line item and it is the one worth paying for 19:14
- VialBot — Testing queue: 2 submissions open, 13 awaiting dispatch. 19:16
- pharmac_pen — update from 16 months ago: retested the same supplier, result came back better, logged both 19:31

quick one certificate said 96.8 and the independent came back 99.4, is that a problem
thats not great
