Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.

Epithalon 10-Vial Kit
Epithalon – 10mg (Lyophilized Peptide) 10 vial kit – For Research Use Only
Epithalon 10 vial kit (also known as Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the naturally occurring pineal gland peptide Epithalon 10 vial kit. It is widely studied for its potential anti-aging, telomerase-activating, and longevity-enhancing effects. Research suggests that Epithalon 10 vial kit may promote telomere extension, support circadian rhythm regulation, and improve oxidative stress resistance. It is a popular compound in studies involving cellular aging, pineal gland function, and DNA repair mechanisms. Product Details: Peptide: Epithalon 10 vial kit(Ala-Glu-Asp-Gly) Purity: >98% Form: Lyophilized powder Quantity: 10mg per vial Storage: Store at -4°F (-20°C). After reconstitution, refrigerate at 36–46°F (2–8°C) and use within 30 days. Grade: For research purposes only. Not for human consumption, therapeutic, or diagnostic use. Potential Research Applications: Telomerase activation and cellular longevity studies Anti-aging and pineal gland function research Circadian rhythm and melatonin regulation studies DNA repair and oxidative stress resistance models For laboratory research only.
