Medications like metformin or acid blockers can also play a role
What a Pre-Mixed Reta+Cagri COA Should Include Identity confirmation (both compounds) Mass spectrometry showing two distinct peaks at the expected molecular weights: Retatrutide: ~4731 Da Cagrilintide: ~3775 Da HPLC chromatogram showing two well-resolved peaks at the expected retention times Purity testing (both compounds) HPLC purity for retatrutide: 97%+ (research-grade floor) HPLC purity for cagrilintide: 97%+ (research-grade floor) Each compound assessed independently not a single combined purity number Ratio quantification Reported as the actual mass ratio in the vial (e.g., "12.4 mg retatrutide : 2.6 mg cagrilintide" or "83% retatrutide / 17% cagrilintide by mass") Match to the labeled ratio (5:1 = 83.3% / 16.7%) Contamination testing Bacterial endotoxin Heavy metals Residual solvents Red Flags Specific to Pre-Mixed Blends COA reports a single purity number without breaking it down per compound

For example, TET1 levels are decreased in the eutopic endometrium of infertile women with endometriosis, contributing to dysregulated DNA methylation patterns

Thanks again, even my nutty Aquarian brain can grasp that
An alanine is substituted at position 15, which researchers posit may provide some support for overall cellular bioactivity
