Testing Services
Review core analysis, optional tests, and the reference catalog below. We confirm the testing scope for your formulation before approving shipping.
Core analysis
One primary COA is included with core analysis.
Identity, chromatographic purity, and peptide-content testing do not establish:

Add a named copy for the same tested vial, with its own Report Number and separate publication consent.
Compounds & blends
Our expanding reference library supports identity comparison, chromatographic purity assessment, and method development for individual research compounds, proteins, peptide blends, and compounded formulations.
Reference targets include current and planned work. A listed name does not guarantee that its quantitative method is qualified. We confirm the available tests for your vial before approving shipping.
These formulations are covered by our planned component reference library. Finished-blend testing requires qualification of the specific formulation and separation of its components.

We consider peptide formulations from local and other compounding pharmacies, including preparations with added amino acids, vitamins, preservatives, or other excipients. Contact us before shipping so we can confirm the testing scope for your exact formulation.
Include a photo of the pharmacy label, the complete ingredient list, the stated concentration of each ingredient, the vial volume, and the lot or prescription reference. For vitamin B12, include the specific form listed on the label, such as cyanocobalamin or methylcobalamin.
Testing is agreed for the requested peptide or protein. Added glycine, B12, preservatives, and other ingredients are not automatically identified or quantified; each additional measurement requires an appropriate qualified method. Formulation ingredients can affect sample preparation and interpretation.

COAs are emailed as attachments and remain private by default. You may authorize public release under a name or alias, with the option to keep failed and inconclusive reports private. ZAVCO does not sell customer information.
Peptide and protein samples by prior arrangement. Our scope includes research peptide vials, HGH (somatropin), and pharmacy-compounded peptide formulations accepted after review of their ingredients and sample requirements.
We do not accept oils, oral products, hCG, testosterone or other anabolic steroids, cannabis or THC products, or any other controlled substance. Ask before shipping if you are unsure whether a sample fits the testing scope.
