Best Peptide Brands Compared: Full Vendor Breakdown

The research peptide market has no single regulatory body verifying what vendors sell. That makes vendor selection one of the most consequential decisions a buyer faces. We catalog every brand in our directory and compare them on product range, pricing, form factor, COA policy and the information visible on their product pages. Seven brands appear below, spanning lyophilized vials, topical formulations and prescription telehealth channels. We checked every product page in October 2026 and report only what each page displays.

How These Brands Are Evaluated

Criteria and Methodology

Brands are scored on five dimensions: product range (how many peptides offered), pricing transparency (is price per milligram calculable), COA availability (is a lot-specific certificate displayed), form factor (vials, topicals, prescriptions) and shipping origin. No payment is accepted from brands to appear in this directory. The evaluation is limited to what the product pages show publicly. If information is missing from a page, the gap is noted.

What Cannot Be Verified

A published COA is better than no COA, but we have not independently confirmed that any COA matches the contents of shipped vials. A vendor may change documentation, pricing or stock at any time. This page reflects a snapshot that is updated periodically with the verification date noted.

All Brands Compared

PeptideGod: Widest Catalog, No Public COA

Product Range and Pricing

PeptideGod offers six lyophilized peptide products, making it the broadest single-vendor catalog in our directory. Prices range from $29.95 (Epithalon) to $59.95 (BPC-157 + TB-500 blend). The standout is the blend product, which combines two peptides that are commonly discussed as a stack. PeptideGod is also the only vendor in our catalog selling standalone TB-500 ($35.00), standalone Ipamorelin ($39.95) and standalone Epithalon ($29.95).

Documentation Gap

None of the six product pages display a COA, purity percentage, vial milligram amount or testing lab reference. This applies uniformly across the catalog. The prices are competitive on a sticker basis, but price per milligram cannot be calculated without knowing the vial size. A $34.95 vial could cost $3.50/mg (if 10 mg) or $6.99/mg (if 5 mg). The customer simply cannot tell from the product page.

Who PeptideGod Suits

Buyers who want access to peptides that no other single vendor carries (TB-500, Epithalon, Ipamorelin as standalones) and who prioritize low sticker price over pre-purchase documentation. For a detailed review, see our PeptideGod vs Real Peptides comparison.

Real Peptides: Full Documentation, Smaller Catalog

Product Range and Pricing

Real Peptides carries four peptide products and bacteriostatic water. All peptide vials are 10 mg. Prices range from $4.80 (BAC water) to $45.60 (Tesamorelin). The catalog is narrower than PeptideGod, with no TB-500, no Epithalon and no standalone Ipamorelin. It does offer Tesamorelin and a Tesamorelin + Ipamorelin blend, which PeptideGod does not carry.

COA Transparency

Every peptide product page shows a lot-specific COA reporting HPLC purity of 99% or higher, mass spectrometry data and endotoxin screening. This is the highest level of pre-purchase documentation among research vendors in our directory. No independent lab testing of their shipped products has been conducted on our end. The COA is only as trustworthy as the issuing lab and supply chain. For more on evaluating purity certificates, see our guide to reading a peptide COA.

Neurogan Health: Affordable GHK-Cu Topicals

Products and Pricing

Neurogan Health sells two GHK-Cu copper peptide products. The Face Cream costs $20 and contains 1200 mg of GHK-Cu at 2% concentration. It holds a 4.9-star rating from 34 reviews. The Hair Serum costs $55 and contains 2400 mg of GHK-Cu at 4% concentration, with a 4.4-star rating from 151 reviews. These are the most affordable GHK-Cu topicals we have found across all vendors.

Form Factor Advantage

Topical products do not require reconstitution, injection equipment or cold storage. They are applied directly to skin or scalp. The tradeoff is that delivery is limited to surface tissues. GHK-Cu topicals cannot reach tendons, joints or internal organs. For skin and hair goals, this is appropriate. For systemic tissue repair, it is not.

Scantifix: Mid-Range GHK-Cu Topical

Product and Positioning

Scantifix sells a GHK-Cu topical at $49.00. The product page features customer reviews. Scantifix sits between Neurogan ($20 for a face cream) and DoctorDerm ($74.50 for a prescription formula) in terms of price positioning. Specific concentration and milligram data should be checked on their current product page.

How It Compares to Neurogan

At $49, Scantifix costs $29 more than Neurogan's Face Cream for a GHK-Cu topical. The Neurogan product states its GHK-Cu content (1200 mg at 2%), while Scantifix's page does not list the same level of ingredient detail. Both are over-the-counter topical products without prescription requirements. The decision between them depends on whether the customer values Neurogan's lower price and stated concentration or Scantifix's customer review base.

DoctorDerm: Prescription Copper Peptide

Telehealth Model

DoctorDerm offers a Copper Peptide Complex at $74.50 through a telehealth dermatology platform. This is the most expensive GHK-Cu product in our directory. The prescription pathway includes physician oversight, which none of the OTC products provide. A dermatologist reviews the case before the product is dispensed, adding a layer of medical judgment to the process.

Price Premium Analysis

The $74.50 price is 3.7 times Neurogan's $20 face cream and 52% more than Scantifix at $49. For buyers who want medical supervision and are comfortable with the cost, this is the relevant option. For those who do not require a prescription and are focused on value, the price premium is substantial.

BiltRx and Arc-1: Telehealth Peptide Therapy

BiltRx and Arc-1 operate as telehealth platforms connecting patients with physicians who can prescribe peptide therapy protocols through compounding pharmacies. Pricing requires a consultation and varies by protocol. These services represent a different category from research chemical vendors. The products come from compounding pharmacies with pharmaceutical oversight, but specific pricing and peptide selection depend on the prescribing physician.

How Telehealth Differs from Direct Purchase

The prescription pathway adds medical oversight, personalized dosing and a regulated supply chain. It also adds cost, waiting time and the requirement to qualify medically. Direct purchase from research vendors like PeptideGod or Real Peptides is faster and cheaper but carries no physician involvement. These two models serve different audiences and should not be directly compared on price alone. BiltRx and Arc-1 appear here for completeness but cannot be evaluated on a per-vial basis since pricing is consultation-dependent.

Brand Selection by Priority

What to Choose

For Full Documentation and Verified Purity

If your priority is purchasing a peptide with a published lot-specific COA, confirmed milligram amount and HPLC purity data, Real Peptides is the strongest option in our directory. Their BPC-157 10 mg at $43.20 ($4.32/mg) comes with the most thorough pre-purchase documentation available among research peptide vendors in our catalog.

For the Broadest Selection at Budget Prices

If you want access to six different peptides including TB-500, a BPC+TB500 blend and Epithalon, PeptideGod is the only single vendor covering all of them. Prices start at $29.95. The tradeoff is the absence of COA documentation and milligram amounts on product pages. Price per milligram cannot be calculated.

For a Topical Peptide Under $25

If you want a GHK-Cu copper peptide product that requires no reconstitution and no injection, Neurogan Health's Face Cream at $20 is the lowest-cost entry point in our catalog. It contains 1200 mg of GHK-Cu at 2% concentration and has a 4.9-star rating from 34 verified reviews. The Hair Serum at $55 offers a higher concentration (4%) for scalp application.
