Peptides are short chains of amino acids (typically 2-50 amino acids) that act as building blocks of proteins. They play crucial roles in many biological processes, including hormone regulation, immune response, and cell signaling. Research peptides are synthetic versions used in laboratory settings to study these biological mechanisms.

Yes, research peptides are legal to purchase for laboratory and research purposes. They are not intended for human consumption, medical use, or veterinary use. All products sold by CrystalPeptides are strictly for research use only.

Research peptides are typically administered via: • Subcutaneous injection — most common method, using an insulin syringe for precise dosing • Intranasal delivery — using pre-mixed nasal spray formulations for non-invasive administration • Intramuscular injection — used for certain formulations requiring deeper tissue delivery The method depends on the peptide type and research objectives. Nasal sprays offer convenience, while vials provide more flexibility in dosing.
