Epithalon: Complete Research Guide for Laboratory Use

Epithalon (also written Epitalon) is a synthetic tetrapeptide bioregulator modeled on a peptide fragment of the natural pineal hormone epithalamin. It is widely studied in longevity research for influence on telomerase activity, circadian regulation, and cellular senescence. For research teams sourcing Epithalon, the most important variables are sequence fidelity, residual solvents, endotoxin load, and traceable batch documentation. Every vial of Epithalon supplied by Quality Peptide USA is American-synthesized, lot-controlled, and released only after independent HPLC-MS and LAL verification.

Epithalon is referenced across Telomerase expression studies, Circadian / pineal regulation research, Cellular senescence models and adjacent investigative domains. As triple-receptor and dual-agonist research peptides expand the pharmacological toolbox, Epithalon continues to serve as a reference compound in comparative assays. Investigators routinely pair it with companion peptides from the Glow stack, Wolverine stack, or GHRH/GHRP secretagogue blends depending on study design.

Reconstitute Epithalon under sterile technique with bacteriostatic water (0.9% benzyl alcohol). Lyophilized vials remain stable refrigerated at 2–8°C; reconstituted aliquots should follow the storage window listed on the product page. Avoid freeze/thaw cycling, exposure to UV light, or contact with reactive metals. For prolonged storage, single-use aliquots in low-binding tubes at −20°C preserve sequence integrity.

Every batch of Epithalon passes RP-HPLC (≥ 99% purity threshold), ESI mass spectrometry confirmation, Karl Fischer water content, and a Limulus Amebocyte Lysate endotoxin screen below 0.10 EU/mg. Certificates of analysis are published with every order — no email request required.

American-synthesized research peptides eliminate the customs delays, opaque batch chains, and inconsistent cold-chain handling associated with overseas suppliers. Quality Peptide USA synthesizes, lyophilizes, and ships Epithalon from domestic facilities, with cold-pack dispatch on every order placed before the 2 PM EST cut-off.
