Peptides consist of amino acid residues connected by peptide bonds. Molecular sequence and structure influence their interactions in a research system. Similar names or amino acid counts do not necessarily imply the same function.
Not every compound in the catalog is a peptide. NAD+ is a dinucleotide coenzyme, while HGH is a protein hormone. Understanding material identity helps you select relevant scientific references.
Cell-culture findings, animal studies and clinical trials have different scopes. Findings for a molecule do not automatically apply to every similarly named product.
A COA (Certificate of Analysis) contains analytical results for a specific batch. Each batch may have different results and documentation. Contact the Onyx team through WhatsApp to confirm the COA matching your product and lot number.
Identity
Does the analytical method support the claimed compound identity?
Purity
What does the method measure, and how is the result expressed? A label percentage alone does not describe the test method.
Quantity & context
Purity is not the same as fill mass, sterility or endotoxin limits. Each characteristic requires appropriate data.
Include the product name and batch/lot number, if available, when contacting our team. The Onyx team will help confirm document availability and the correct batch match through WhatsApp before you order.
mg measures mass. mL measures volume. mg/mL expresses the mass of material in each mL of solution. They are different quantities, so a vial’s labeled amount does not directly state the solution concentration.
MATHEMATICAL EXAMPLE10 mg ÷ 2 mL = 5 mg/mL
The example uses final solution volume; it is not an administration protocol.
Use the correct material mass and final volume. IU expresses biological activity and cannot be converted to mg using one universal factor for every material.
