Peptide Brands Compared: Every Vendor Reviewed

The peptide vendor market has more brands than it has transparency. We reviewed seven brands that appear across our product data: PeptideGod, Real Peptides, Neurogan Health, Scantifix, DoctorDerm, BiltRx and Arc-1. Each one was evaluated on the same criteria: product range, pricing, milligram disclosure, COA availability and shipping. What follows is the most complete comparison we could build from what is publicly visible on product pages. No vendor paid for placement. No scores were influenced by affiliate relationships. Neither these brands nor their products are FDA-approved for human therapeutic use. For background on how we evaluate vendor credibility, see our buying guide.

All Seven Brands Compared

The table below is the core comparison. It shows what each brand sells, what form the products take, the price range, whether price per milligram can be calculated and whether a Certificate of Analysis appears on the product page. Every product listing was checked and what was visible to a buyer before purchase was recorded.

Two brands dominate the lyophilized peptide market in this comparison: PeptideGod and Real Peptides. They are the only vendors selling injectable research peptides with live, accessible product pages. The remaining five brands occupy different categories entirely. Neurogan Health and Scantifix sell GHK-Cu topicals. DoctorDerm operates a telehealth prescription model. BiltRx returned a 403 error when we attempted to access their product pages. Arc-1 appears on brands listings at $199.99 but with no accessible product detail.

Price per Milligram: Who Discloses, Who Does Not

Price per milligram is the only honest way to compare peptide value across vendors. It requires two numbers: the price and the milligram content. When a vendor withholds one of those numbers, the comparison breaks down.

Only two brands allow verifiable per-milligram pricing: Real Peptides and Neurogan Health. Real Peptides discloses 10 mg per vial across all peptide products, producing a consistent $4.32/mg price point for BPC-157 and MOTS-c. Neurogan Health lists 1200 mg of GHK-Cu at 2% concentration for $20.00, which works out to $0.017/mg. Topical GHK-Cu is fundamentally different from a lyophilized peptide vial, so comparing those per-milligram figures directly would be misleading.

PeptideGod's six products all lack milligram disclosure. Scantifix does not list concentration. DoctorDerm operates as a prescription service. Arc-1 shows only a price point with no accessible product detail. BiltRx cannot be evaluated at all.

Certificate of Analysis: Brand by Brand

A COA shows what is inside the vial before you buy it. HPLC purity, mass spectrometry confirmation and endotoxin screening are the minimum components of a useful COA. Here is what each brand provides.

Real Peptides is the only brand in this comparison with publicly available, lot-specific Certificates of Analysis on their peptide product pages. On the PeptideGod product page there is no COA, no stated purity and no named testing laboratory for any of their six products. This does not prove their products are impure. It means the purity cannot be verified by the buyer before purchase using publicly available information.

Scantifix has reviews on their GHK-Cu product page but no COA. DoctorDerm sells a prescription product, which falls under a different regulatory framework. Neurogan Health's GHK-Cu cream is a cosmetic, which has its own set of manufacturing standards separate from research peptide documentation. BiltRx and Arc-1 cannot be evaluated at all on this criterion.

Shipping and Ordering Comparison

For lyophilized peptide buyers, Real Peptides has a practical advantage: you can buy the peptide and the bacteriostatic water needed to reconstitute it in one order. PeptideGod does not sell BAC water, so buyers need a second source. Both ship from US-based stock, avoiding customs delays that come with international peptide orders.

Brand-by-Brand Breakdown

PeptideGod

PeptideGod has the widest lyophilized peptide selection: six products spanning BPC-157, TB-500, a BPC+TB500 blend, MOTS-c, Ipamorelin and Epithalon. The price range is $29.95 to $59.95. We found no COA, no milligram disclosure and no purity percentage on any product page. The product pages include a price, product image, short description and add-to-cart button. For researchers who need TB-500, the BPC-157 + TB-500 blend or Epithalon, PeptideGod is the only vendor in this comparison carrying those products. The documentation gap is the largest trade-off.

Real Peptides

Real Peptides lists four peptide products plus USP-grade bacteriostatic water. Every peptide vial states 10 mg, shows HPLC purity of 99% or higher and includes a published lot-specific COA. The product range is narrower, but every listing meets documentation standards that most vendors in this comparison do not. BPC-157 at $43.20, MOTS-c at $43.20, Tesamorelin at $45.60 and the Tesa+Ipa blend at $43.20. The BAC water at $4.80 adds convenience for one-stop ordering. Real Peptides specifically claims 24-hour US shipping.

Neurogan Health

Neurogan Health sells a GHK-Cu cream at $20.00. It contains 1200 mg of GHK-Cu at 2% concentration. The product has a 4.9-star rating from 34 reviews. This is a topical cosmetic product, not a lyophilized research peptide. It requires no reconstitution and no injection supplies. GHK-Cu has published collagen synthesis data (PMID 26236730) and wound healing data (PMID 18644225). For skin-focused research interests, Neurogan offers the lowest price point and the most reviews in this comparison.

Scantifix

Scantifix sells a topical GHK-Cu product at $49.00. The product page includes user reviews but does not list the concentration of GHK-Cu. On the product page there is no COA. Without knowing the GHK-Cu concentration, value comparison against Neurogan Health's product ($20.00 for 1200 mg at 2%) is not possible. The product may be comparable, but the data to confirm that is missing from the listing.

DoctorDerm

DoctorDerm operates a telehealth model, selling a Copper Complex topical at $74.50. This is a prescription product obtained through their telehealth consultation service. The pricing is the highest for a copper peptide product in this comparison. The prescription model means a healthcare provider is involved in the purchasing process, which adds a layer of medical oversight absent from direct-to-consumer peptide vendors. Whether the prescription product contains more active compound or higher purity than over-the-counter alternatives is not determinable from the product listing alone.

BiltRx

Attempts to access BiltRx product pages returned a 403 forbidden error. No product data, pricing, COA information or shipping details could be evaluated. The brand appears on peptide vendor listings, but the inability to access their site makes any assessment impossible at this time. This section will be updated if access becomes available.

Arc-1

Arc-1 appears on brand listing pages with a price of $199.99. No detailed product page was accessible for review. The product category, form, milligram content, purity documentation and shipping details are all unknown. At $199.99, it is the most expensive listing in this comparison, but without knowing what the product is or contains, the price is not interpretable.

What to Choose: Three Scenarios

Scenario 1: Purity Documentation Is Non-Negotiable

Real Peptides. No other brand in this comparison publishes lot-specific COAs with HPLC purity data and endotoxin screening on every product page. If your research protocol requires documented purity, Real Peptides is the only brand here that meets that standard. The product range is narrower (BPC-157, MOTS-c, Tesamorelin, Tesa+Ipa blend), but every listing backs up its claims with published analytical data. Price per milligram is verifiable at $4.32/mg for BPC-157 and MOTS-c. For more detail, see our PeptideGod vs Real Peptides comparison.

Scenario 2: Product Variety Is the Priority

PeptideGod has the broadest lyophilized peptide catalog. Six products including TB-500 and Epithalon, neither of which any other brand in this comparison carries. The BPC-157 + TB-500 blend at $59.95 is exclusive to PeptideGod. If your research requires compounds outside the BPC-157 and MOTS-c overlap, PeptideGod is the only option among lyophilized vendors reviewed here. On the product page there is no COA for any product, so this choice comes with a documentation trade-off.

Scenario 3: Topical GHK-Cu for Skin Research

Neurogan Health offers the best documented and most affordable option. At $20.00 for 1200 mg at 2% concentration with a 4.9-star rating from 34 reviews, it is cheaper and better reviewed than Scantifix ($49.00, concentration not listed) and significantly cheaper than DoctorDerm ($74.50, prescription required). For skin-focused GHK-Cu research, Neurogan Health delivers the most value on paper. The product is a topical cosmetic, not a research peptide vial, so it occupies a different product category than what PeptideGod and Real Peptides sell.
