What Is Ion Peptide?

Ion Peptide is a US-based research compound vendor founded in 2022. What separates them from the crowded field of peptide vendors is catalog scope: while most competitors focus on 15–25 core SKUs (BPC-157, TB-500, BPC/TB stacks, a handful of GLP-1s), Ion Peptide has expanded to 92 products by adding product categories most vendors skip entirely.

Those categories include:

• Classic research peptides — BPC-157, TB-500, GHK-Cu, PT-141, Selank, Epithalon, and more
• GLP-1 receptor agonists — semaglutide, tirzepatide, retatrutide
• Buccal delivery strips — NAD+, B12, glutathione (non-injectable delivery formats)
• Topical/cosmetic peptides — GHK-Cu hair serum, copper peptide skin serum
• Khavinson bioregulator peptides — Pinealon, Bronchogen, Cortagen, Cartalax
• PDRN (polydeoxyribonucleotide)
• Raw powders and lab consumables

This breadth is genuinely unusual. The vendor hub page at /vendors/ion-peptide has the full product catalog and direct affiliate links.

Pricing Analysis

Ion Peptide prices most SKUs at or below the domestic market median. Their strongest value proposition is on GLP-1 agonists and the three most-researched peptides:

Prices fluctuate with supply — always confirm at time of purchase. But from regular price monitoring, Ion Peptide's GLP-1 pricing is notably below the market median, making them a first-check for researchers who cycle semaglutide or tirzepatide regularly.

Product Categories In Depth

Research Peptides — The Core Catalog

#### BPC-157

BPC-157 (Body Protection Compound-157) is the highest-turnover research peptide on the market and Ion Peptide's most competitively priced flagship. The 15-amino-acid sequence (GEPPPGKPADDAGLV) is studied primarily in gastrointestinal healing, tendon/ligament repair, and inflammation models.

Ion Peptide's BPC-157 5mg comes as a lyophilized vial with purity ≥99% by HPLC. At ~$19.99 per 5mg, it sits at the low end of the domestic price range.

See the full research profile: BPC-157 compound page

#### TB-500

TB-500 (thymosin beta-4 fragment) is the second most common peptide in musculoskeletal research and is frequently stacked with BPC-157. It promotes tissue repair via actin G-binding, accelerates angiogenesis, and has anti-inflammatory properties.

Ion Peptide's TB-500 5mg runs ~$24.99 — consistently below most major competitors.

See: TB-500 compound page

#### GHK-Cu

GHK-Cu (copper tripeptide-1) has one of the strongest topical evidence bases of any cosmetic peptide, with documented effects on collagen production, wound healing, and hair follicle stimulation. Ion Peptide offers it three ways:

1. Raw powder 50mg — for researchers formulating custom solutions
2. Hair Growth Serum 30ml — 2% GHK-Cu in a penetration-improving scalp serum
3. Copper Peptide Skin Serum 30ml — 1% GHK-Cu in a hyaluronic acid carrier

The ready-to-use topical formats are unusual — most peptide vendors only sell injectable or raw powder forms.

See: GHK-Cu compound page

#### Other Notable Peptides

• Epithalon 10mg — Pineal tetrapeptide, telomerase activation research (compound page)
• PT-141 10mg — Bremelanotide, melanocortin agonist (compound page)
• Selank 5mg — Anxiolytic/nootropic heptapeptide (compound page)
• PDRN 5ml solution — Polydeoxyribonucleotide, adenosine A2A agonist

GLP-1 Receptor Agonists

Ion Peptide carries the complete current-generation GLP-1 stack — semaglutide, tirzepatide, and retatrutide — and prices all three below the domestic market median.

#### Semaglutide

Semaglutide is a GLP-1 receptor monoagonist, the compound class behind Ozempic and Wegovy in the pharmaceutical market. Research applications cover metabolic syndrome, obesity, glycemic control, and cardiovascular disease models.

Ion Peptide's Semaglutide 5mg at ~$34.99 is among the most competitive domestic prices we've tracked.

#### Tirzepatide

Tirzepatide (Mounjaro/Zepbound in the pharmaceutical market) adds dual GIP/GLP-1 receptor agonism. Phase 3 SURMOUNT-1 trial data showed superior weight loss outcomes compared to semaglutide monotherapy.

Ion Peptide's Tirzepatide 5mg at ~$44.99 undercuts most domestic competitors by 20–40%.

#### Retatrutide

Retatrutide (LY3437943) is the newest compound in this class — a triple GIP/GLP-1/glucagon receptor agonist. It's the most mechanistically advanced GLP-1-class peptide currently available for research and is significantly harder to source than semaglutide or tirzepatide.

Ion Peptide's Retatrutide 5mg at ~$49.99 is a strong price for a compound that commonly runs $70–$90+ at other vendors.

Buccal Delivery Strips — Ion Peptide's Most Unique Category

This is the category that most distinguishes Ion Peptide from every other vendor on BodyHackGuide. Buccal dissolving strips deliver compounds through the oral mucosa — bypassing first-pass liver metabolism and avoiding needles entirely.

They offer three buccal formats:

#### NAD+ Buccal Strips (250mg / 30ct)

Oral NAD+ supplements are poorly absorbed — most degrades before reaching circulation. IV NAD+ is highly effective but requires clinic access. Ion Peptide's NAD+ strips at 250mg per strip are one of the highest-dose buccal NAD+ products on the research market.

For researchers studying NAD+ biology who want a non-injectable delivery format, this is a meaningful option.

See: NAD+ compound page

#### B12 Buccal Strips (1000mcg methylcobalamin / 30ct)

Ion Peptide's B12 strips use methylcobalamin, the bioactive form, at a therapeutic 1000mcg dose. Buccal B12 is well-studied and effective at achieving serum response comparable to intramuscular injection in deficiency models.

#### Glutathione Buccal Strips (200mg / 30ct)

Oral glutathione bioavailability is famously poor — the tripeptide is cleaved by GI peptidases before absorption. Buccal glutathione strips bypass this by absorbing through the buccal mucosa. 200mg per strip, 30ct pack.

Khavinson Bioregulator Peptides

The Khavinson bioregulators are a family of short organ-targeting peptides developed by Vladimir Khavinson and the St. Petersburg Institute of Bioregulation and Gerontology, originally for Soviet military medicine (radiation recovery, battlefield injury). They're arguably the most obscure compound category Ion Peptide carries — and the one with the fewest domestic alternatives.

Ion Peptide carries four core Khavinson bioregulators:

These peptides are mechanistically distinct from research peptides like BPC-157: they are proposed to act by directly binding double-stranded DNA promoter regions in target tissues, modulating gene expression rather than ligand-receptor signaling. The research base is primarily Russian-language and preclinical.

For researchers exploring longevity, organ-specific tissue maintenance, or the Khavinson protocol, Ion Peptide is one of the easiest domestic sources for the full set.

Purity Testing and Quality Assurance

Ion Peptide verifies products via third-party HPLC for identity and purity. Flagship peptides (BPC-157, TB-500, semaglutide) run ≥99% purity. Less common compounds run ≥98%.

COA requests can be submitted via their website contact form. Include your order number and the specific batch — turnaround is typically 1–3 business days.

Use BodyHackGuide's COA Reader tool to interpret HPLC certificates if you're new to reading test reports.

Pros and Cons

Pros

• Widest catalog of any vendor on BHG — 92 products across 6+ categories
• Best GLP-1 pricing we've tracked domestically on semaglutide, tirzepatide, and retatrutide
• Unique buccal strip line — the only vendor here offering NAD+, B12, and glutathione in buccal format
• Full Khavinson bioregulator set — Pinealon, Bronchogen, Cortagen, Cartalax in one place
• Ready-to-use GHK-Cu topicals — hair and skin serums alongside raw powder
• Third-party HPLC testing with COA on request
• Fast fulfillment (24–48h domestic)
• Three payment methods including crypto and ACH

Cons

• No public COA library — must request per-batch; not all vendors require you to ask
• Topical product URLs and availability can shift — high-demand items go out of stock faster than peptide vials
• International shipping is limited on GLP-1 agonists due to import restrictions in many jurisdictions
• Bioregulator research base is primarily Russian-language — harder to vet independently vs. compounds with PubMed-indexed English-language trials

How Ion Peptide Compares to Other BHG Vendors

Adera is the better choice if you're researching nootropic stacks (Sabroxy, Theacrine), sleep compounds (Kavain), or social anxiety compounds (Phenibut). Ion Peptide is the better choice for peptide-primary protocols, especially anything involving GLP-1 agonists, buccal delivery, or bioregulators.

Verdict

Ion Peptide earns a strong recommendation for researchers who need:

1. The broadest catalog from a single domestic vendor
2. Competitive GLP-1 pricing (their clearest pricing advantage)
3. Buccal strips as an injectable-free delivery format for NAD+, B12, or glutathione
4. Bioregulator peptides that are otherwise hard to source domestically
5. Ready-to-use GHK-Cu topicals without custom formulation

For standard peptide orders (BPC-157, TB-500, core stack), they are priced competitively and test reliably. The unique categories — buccal strips, bioregulators, topicals — make them the default recommendation when a protocol extends beyond the basic peptide core.
