Purity Testing and COA for Tirzepatide

Dear Analytical Team, I’m reaching out to inquire about analytical testing services for a peptide sample I have in my possession, specifically, Tirzepatide. I would like to verify both the identity and purity of this peptide through independent testing and obtain a Certificate of Analysis (COA) for documentation purposes. I am requesting the following: -Purity analysis, preferably by HPLC -Identity confirmation via mass spectrometry -Detection of any undeclared additives or contaminants, if possible -Issuance of a COA reflecting the results This is a single vial of lyophilized powder, purchased for research purposes. Could you please provide information on: 1. Pricing for these services 2. Required sample amount 3. Turnaround time 4. Shipping and submission instructions 5. Any necessary forms or intake process for new clients If additional or recommended testing (e.g., amino acid sequencing, residual solvent testing, etc.) is available, I’d appreciate that information as well.
