Analytical Testing Panel
Verified by Janoshik Analytical — full panel, every batch. Second independent lab confirmation is being added batch by batch.
Quantifies the main peak against related-substance peaks, so the stated purity percentage is measured rather than assumed.
Every IGF-DES — Precision Growth Factor Research Peptide lot passes all 8 stages before it is released. Expand a stage to see the method and why we run it.
- Method on the COARP-HPLC (UV 214 nm)Why Ares runs it
Quantifies the main peak against related-substance peaks, so the stated purity percentage is measured rather than assumed.
- Method on the COAQuantitative HPLC mass/concentration assayWhy Ares runs it
Confirms the vial actually contains the labeled amount — purity alone says nothing about how much material is in the vial.
- Method on the COAMass Spectrometry (ESI-MS)Why Ares runs it
Confirms the measured molecular mass matches the declared compound — the check that catches a mislabeled or substituted vial.
- Method on the COAICP-MSWhy Ares runs it
Screens for elemental contaminants carried over from synthesis, reagents, or packaging.
- Method on the COAMembrane filtration, USP <71> methodologyWhy Ares runs it
Checks the finished lyophilized vial for microbial growth after fill and closure.
- Method on the COALAL assay (kinetic chromogenic)Why Ares runs it
Measures bacterial endotoxin load, a contamination marker that purity testing alone will not reveal.
- Method on the COAIndependent batch review against release specificationWhy Ares runs it
Ties the analytical numbers back to the paperwork — the lot you receive is the lot on the certificate.
- Method on the COALC-MS/MS targeted screenWhy Ares runs it
A contamination check most research suppliers never run, and the reason we run it on every batch regardless of compound.
PASS reflects the batch release standard every lot must meet before it ships. Per-lot results are published on that lot's Certificate of Analysis.
