This is gold, amy_econ_NJ. Thank you for your dedication to testing and data collection.
A few analytical observations:
1. Low standard deviations (0.39-0.53%) across all vendors indicate tight manufacturing control. For comparison, published data on generic pharmaceutical peptides typically shows SD of 0.5-1.5%.
2. No temporal trend is really important. If we saw purity declining over time, that would suggest deteriorating manufacturing practices. The data shows no such trend for any vendor.
3. Tirzepatide purity is slightly higher on average (97.9%) than semaglutide (97.7-97.9%). This might seem counterintuitive since tirz is a more complex molecule, but it could reflect newer, more optimized synthesis routes.
4. The ANOVA non-significance confirms what we've suspected: all three verified vendors are drawing from essentially the same quality distribution. You could order from any of them with equal confidence in product quality.
This dataset should be in the wiki permanently.
