What is the minimum order quantity for Cognitive & Neuro peptides?

Minimum order quantities vary by compound. Contact Peptide Direct with specific requirements to discuss MOQs and pricing.

What are longevity peptides?

Longevity peptides are short chains of amino acids that interact with biological ageing mechanisms at the cellular level. The core compounds in this category include Epithalon (studied for telomerase activation), MOTS-c (a mitochondria-derived peptide involved in metabolic regulation), NAD+ (a coenzyme essential to cellular energy metabolism), and SS-31 (a mitochondrial-targeting antioxidant peptide). Each operates through a distinct mechanism, but all are connected by the shared goal of supporting cellular function as organisms age.

What purity standards do your longevity peptides meet?

All longevity peptides supplied by Peptide Direct — including Epithalon, MOTS-c, NAD+, and SS-31 — meet a minimum purity of ≥98% as verified by HPLC (High-Performance Liquid Chromatography) analysis. Every production batch is accompanied by a Certificate of Analysis (CoA) detailing purity data, compound identity confirmation, and batch traceability. Our manufacturing processes operate under GMP and ISO 9001:2015 certified conditions.

Do you supply longevity peptides at wholesale volumes?

Yes. Peptide Direct is a wholesale-first supplier. We supply all four longevity peptides — Epithalon, MOTS-c, NAD+, and SS-31 — at bulk and wholesale volumes to clinics, wellness brands, supplement distributors, and resellers globally. Minimum order quantities and pricing tiers are available on request via our contact form or by calling +44 788 048 5232.

Can I get private label packaging for longevity peptides?

Yes. Peptide Direct offers comprehensive private label and custom branding solutions for all longevity peptides. This includes custom-branded vials, outer packaging, labelling, and product inserts. Private label is available to qualifying wholesale buyers across all four longevity compounds. Contact our team to discuss minimum order quantities, design specifications, and turnaround times.

What is Epithalon used for?

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide — Ala-Glu-Asp-Gly — based on Epithalamin, a naturally occurring substance isolated from the pineal gland. It is one of the most extensively researched peptides in the longevity field, with studies examining its role in telomerase activation, regulation of the cell cycle, neuroendocrine system support, and antioxidant activity. It is widely supplied to longevity clinics, anti-aging medicine practitioners, and wellness product brands.

How does MOTS-c differ from other longevity peptides?

MOTS-c is unique in that it is encoded within the mitochondrial genome itself — rather than the nuclear genome — making it a mitochondria-derived peptide (MDP). It acts as a metabolic regulator, with pre-clinical research showing effects on insulin sensitivity, glucose metabolism in skeletal muscle, and lifespan in model organisms. Unlike Epithalon (which targets telomeres) or SS-31 (which targets the mitochondrial membrane), MOTS-c primarily operates through metabolic signalling pathways — making it of particular interest in the context of metabolic ageing and age-related metabolic disease.

Do you ship longevity peptides internationally?

Yes. Peptide Direct supplies longevity peptides — Epithalon, MOTS-c, NAD+, and SS-31 — to wholesale buyers worldwide. We have established distribution capabilities across Europe, North America, Asia-Pacific, and other international markets. All shipments comply with relevant international shipping requirements for research-grade peptide compounds. Contact us to discuss shipping to your specific location.
