What are peptides?
Start with amino acids, then see how they connect. Watch two introductions from Khan Academy.

What is a peptide?
A peptide is a short chain of amino acids, joined by peptide bonds. Amino acids also form the longer chains found in proteins.
A peptide's name identifies the molecule. It does not tell you its amount, formulation or whether a finished product is an approved medicine.
Read the NHGRI peptide glossarymg and ml measure different things.
Milligrams (mg) measure mass. Millilitres (ml) measure liquid volume. A 40 mg kit and a 10 ml bottle describe different quantities, so the numbers cannot be compared directly.
Concentration connects the two: mg/ml means the mass of an ingredient in each millilitre. Volume alone does not reveal peptide concentration. The Selank and Semax listings identify any formulation details still awaiting manufacturer confirmation.
Understand the format.
Our pen kits use separate chambers for freeze-dried peptide powder and BAC water. Keeping the components separate describes the product's format; it does not establish a shelf life or storage temperature.
Selank and Semax are presented as liquid sprays in 10 ml bottles. Read each listing for the available ingredient and strength information. Use the manufacturer's batch-specific instructions for storage and expiry.
Read purity in context.
A purity percentage describes a testing result. It does not, by itself, establish the finished product's sterility, concentration or clinical suitability. Ask for the relevant batch documentation when assessing a product.
Research materials and approved medicines are different categories. Product information here explains specifications and formats; it is not dosing or treatment guidance.
