For laboratory and in-vitro research use only. Not for human consumption.
Research peptides are short chains of amino acids used for laboratory, in vitro, or analytical science work. They are not approved for human or veterinary use, and are intended solely for experimental or research purposes.
How should the peptides be stored?
Peptides are best kept in cool, dry conditions. Lyophilized (powder) form should be stored at or below [your recommended temp, e.g. 4°C] and protected from moisture. After reconstitution, use according to lab‑specific guidance and store as indicated on the product page.
How long does shipping take?
Orders placed by 3 PM EST ship the same or next business day. Delivery times depend on the destination; most U.S. orders arrive in 3 business days with standard services.
What is your refund / return policy?
Because these are specialized research compounds, we do not accept returns once product has left the facility (unless there is an error on our part or the product fails QC). If you believe there’s a quality issue, contact us email with your order number and batch/lot info, and we’ll review the COA and options.
Are you responsible for how your peptides are used?
No. All compounds sold by Highlander Labs are for laboratory research use only and are not intended for human or veterinary consumption. We do not condone, support, or accept any misuse of our products.
By purchasing from our site, you agree that you are solely responsible for how these compounds are handled, stored, and used. Highlander Labs assumes no liability for misuse or non-research applications.
