    About Ion Peptide

    Ion Peptide is one of the broadest-catalog peptide research vendors operating in 2026. Their 92-product lineup spans classic research peptides (BPC-157, TB-500, GHK-Cu), GLP-1 receptor agonists (semaglutide, tirzepatide, retatrutide), novel buccal delivery strips (B12, NAD+, Glutathione), copper peptide hair and skin topicals, bioregulator peptides (Bronchogen, Cartalax, Cortagen, Pinealon), PDRN products, raw powders, and laboratory consumables. Products ship from domestic facilities with third-party HPLC purity verification on request. Pricing is consistently competitive — particularly on GLP-1 agonists and high-turnover research peptides like BPC-157, TB-500, and GHK-Cu — making them a frequent first-choice for cost-conscious researchers.

    Mission

    Stock every compound class a peptide researcher needs, price it competitively, test it rigorously, and ship it fast. No vendor lock-in, no inflated margins on popular items, and no artificial scarcity on compounds that should be accessible.

    Founder's Story

    Ion Peptide was built around a straightforward problem: the peptide research space had too many vendors offering too few products, with pricing that drifted upward precisely because buyers had limited alternatives. The founding team, with backgrounds in analytical chemistry and contract manufacturing, designed the catalog deliberately wide — covering peptides, bioregulators, buccal delivery formats, topicals, and GLP-1 agonists under one roof. The buccal strip line came from direct demand: researchers wanted non-injectable NAD+, B12, and glutathione delivery that sidestepped the reconstitution workflow entirely. The bioregulator range (Bronchogen, Pinealon, Cartalax, Cortagen) followed a gap in Western-market availability of the Khavinson peptide family. The lab supplies and raw powders round out a catalog designed to serve the full research lifecycle.

    Third-Party Testing

    Every product page for Ion Peptide includes a Certificate of Analysis (COA) from an independent lab (Third-party HPLC (identity + purity)). COAs confirm identity, purity, and endotoxin levels for research-grade compounds.

    Research Focus

    Triple GLP-1 agonists: semaglutide → tirzepatide → retatrutide

    The GLP-1 receptor agonist class has evolved rapidly. Semaglutide (GLP-1R only) established the baseline for metabolic research. Tirzepatide added dual GIP/GLP-1 activity, producing superior weight-loss outcomes in Phase 3 trials vs. semaglutide alone (SURMOUNT-1). Retatrutide adds glucagon receptor co-agonism, making it a triple receptor agonist — the most mechanistically broad compound in the class. Ion Peptide stocks all three. For research use only; none of these are approved for self-administration.

    Buccal NAD+ vs. oral supplements: why the delivery route matters

    Oral NMN/NR supplements are precursors that must be converted to NAD+ intracellularly. Oral NAD+ itself is poorly absorbed — most is degraded before reaching circulation. Buccal (sublingual) delivery bypasses first-pass metabolism and can achieve meaningful plasma levels directly. Ion Peptide's NAD+ buccal strips at 250mg per strip represent one of the more direct non-injectable NAD+ delivery formats commercially available for research. IV NAD+ remains the gold standard for plasma peak; buccal sits between IV and oral in the delivery hierarchy.

    Khavinson bioregulator peptides: origin and mechanisms

    The Khavinson peptides are a family of short (di- to pentapeptide) organ-specific bioregulators developed by Vladimir Khavinson and the St. Petersburg Institute of Bioregulation and Gerontology from the 1970s onward. The original research program was military-funded and focused on tissue restoration after radiation exposure and battlefield injury. Each peptide is named for the tissue it targets: Pinealon (pineal), Bronchogen (bronchial), Cortagen (cardiac), Cartalax (cartilage), Epithalon (pineal/longevity). The mechanism involves direct binding to double-stranded DNA promoter regions, modulating gene expression in target tissues. Western availability has historically been limited — Ion Peptide is among the more accessible domestic sources for the full set.

    GHK-Cu in topical formulations: cosmetic vs. research use

    GHK-Cu (copper tripeptide-1) is one of the most extensively studied cosmetic peptides, with a substantial PubMed record covering wound healing, collagen stimulation, anti-inflammatory activity, and hair follicle stimulation. Ion Peptide offers it three ways: raw powder (50mg, for researchers who formulate their own solutions), a 2% scalp serum (hair follicle research), and a 1% skin serum in a hyaluronic acid carrier. The topical serum formats are unusual for a peptide research vendor — most sell only injectable or raw powder forms. For researchers studying dermal repair or androgenetic alopecia models, the ready-to-use topical format reduces preparation burden.

    PDRN: polydeoxyribonucleotide and adenosine A2A receptor biology

    PDRN (polydeoxyribonucleotide) is derived from salmon sperm DNA and acts primarily as an adenosine A2A receptor agonist. Research applications span wound healing (particularly in diabetic wound models), anti-inflammatory pathways, and cosmetic tissue regeneration. PDRN is widely used in South Korean aesthetic medicine and has an established clinical literature. Ion Peptide stocks it as a sterile solution, which is the research-standard format for application studies.

    Frequently Asked Questions

    How many products does Ion Peptide carry?+
    As of 2026 Ion Peptide stocks 92 products across peptides, GLP-1 agonists, buccal delivery strips, copper peptide topicals/cosmetics, bioregulator peptides (the Khavinson series), PDRN formulations, raw powders, and laboratory consumables. This makes them one of the widest-catalog single-vendor options in the domestic research peptide market.
    How does Ion Peptide price GLP-1 agonists vs. other vendors?+
    Ion Peptide is consistently priced at or below most domestic competitors on GLP-1 receptor agonists — semaglutide, tirzepatide, and retatrutide. As of our last price check, their semaglutide 5mg and tirzepatide 5mg were among the most competitively priced on the domestic market. Prices fluctuate with supply, so always compare at time of purchase.
    What are buccal delivery strips and why does it matter?+
    Buccal strips dissolve against the mucous membrane inside your cheek, allowing compounds to absorb directly into the bloodstream without a needle, capsule, or first-pass hepatic metabolism. Ion Peptide offers buccal formats for B12, NAD+, and Glutathione — compounds where oral bioavailability is poor and injectable delivery is the typical alternative. For researchers who want NAD+ or glutathione without IV protocols, buccal strips offer a meaningful middle path.
    Where does Ion Peptide source Khavinson bioregulators?+
    The Khavinson bioregulator peptides (Pinealon, Bronchogen, Cortagen, Cartalax, Epithalon, and related compounds) originated from Soviet-era military medicine research and are manufactured synthetically. Ion Peptide stocks the full core Khavinson set — these are significantly harder to source from Western vendors than standard research peptides like BPC-157. HPLC identity confirmation is available on request.
    Does Ion Peptide provide certificates of analysis?+
    Yes. Ion Peptide tests products via third-party HPLC for identity and purity. COA requests can be submitted via the contact form on their site. Purity on flagship products (BPC-157, TB-500, semaglutide series) typically runs ≥99%. Less common compounds may run ≥98%.
    How fast does Ion Peptide ship?+
    Domestic US orders fulfill within 24–48 hours of payment. Shipping method is USPS Priority or UPS Ground by default. Tracking is provided on all orders. Packaging is discreet — nothing on the outer packaging identifies the contents or sender as a peptide vendor.
    What payment methods does Ion Peptide accept?+
    Ion Peptide accepts credit/debit cards, cryptocurrency (Bitcoin, USDC, and others), and ACH bank transfer. Credit card payments process at market rate; crypto payments may receive a discount — check the site at time of order.
    BPC-157 vs TB-500 — which should I research?+
    BPC-157 (pentadecapeptide) and TB-500 (thymosin beta-4 fragment) are often co-researched because they target overlapping but distinct pathways. BPC-157 is primarily studied for gastrointestinal healing and tendon/ligament repair; TB-500 for systemic tissue repair, angiogenesis, and inflammation. The two are frequently combined in musculoskeletal research stacks. Both are among Ion Peptide's most competitively priced and consistently in-stock SKUs. See the BHG BPC-157 and TB-500 compound profiles for research citations.
