Peptide Basics
What is a peptide?
A peptide is a short chain of amino acids. In this category, the term usually refers to compounds studied for signaling roles, which is why Northstar explains products by pathway, category, and research context rather than by trend language.
How are peptides different from proteins?
They use the same amino-acid building blocks, but peptides are shorter and proteins are larger and more structurally complex.
What does research use only mean?
It means the products are presented for lawful research-related purchasing review and product identification, not as approved personal, therapeutic, or diagnostic products.
Why are products grouped by pathway?
Grouping by pathway makes comparison clearer because many buyers think in terms of GH-axis, metabolic, mitochondrial, or repair-related signaling rather than vague outcome claims.
What does lyophilized mean?
Lyophilized means the product is supplied as a freeze-dried powder rather than a ready-made liquid.
Does the mg amount on a vial tell me everything?
No. The listed amount is only one part of the picture. Identity, category, format, documentation path, and whether the product is a blend all matter too.
