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 MT-2 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.

MT-2 research questions
+What is MT-2 (Melanotan II) and what does research study?
MT-2 is a synthetic melanocortin receptor agonist studied in vitro for its effects on melanocortin signaling pathways, particularly MC1R and MC4R. Research literature examines pigmentation biology, appetite regulation, and sexual function endpoints. Sold strictly for laboratory research use — not for human consumption.
+How is MT-2 typically reconstituted in a research setting?
A common laboratory reconstitution uses bacteriostatic water at ratios chosen to match the study's dosing protocol (e.g., 1 mL BAC water per 10 mg vial for a 1 mg / 0.1 mL working concentration). Use the /tools/reconstitution-calculator for exact volumes. For in-vitro research use only.
+How should MT-2 be stored to preserve peptide stability?
Lyophilized MT-2 is typically stored at -20°C protected from light. Once reconstituted, refrigerate at 2-8°C and use within the timeframe specified by the study protocol. Avoid repeated freeze-thaw cycles, which can degrade peptide integrity. For research use only.
+Does Ares Research provide a Certificate of Analysis for MT-2?
Yes. Every MT-2 batch ships with a third-party HPLC and mass-spectrometry Certificate of Analysis documenting identity and purity. COAs are available on the product page and via /coa. Sold for in-vitro research use only — not for human consumption, diagnosis, or treatment.
