All Peptide Brands and Products

Every peptide brand makes promises on its website. We ignore the promises and look at what the product page actually shows. This directory covers all seven brands currently in our review database, assessed on the same criteria: published testing data, disclosed quantities, price transparency and product range. Some brands score well. Others leave us with more questions than answers. A few would not even let us access their website.

How We Evaluate Brands

We pull data from live product pages. That means prices, COA availability, stated purity, milligram amounts and any user reviews visible on the page at the time of collection. We do not interview company representatives, tour manufacturing facilities or rely on social media endorsements. If documentation is missing from the product page, it counts as missing. If a website blocks our access, we note what we could not see. Our editorial policy and affiliate disclosure details are on the safety page.

Peptide God

PeptideGod is a US-based peptide supplier with five products in our database: BPC-157 ($34.95), TB-500 ($35.00), MOTS-C ($49.95), Epithalon ($29.95) and a BPC-157 + TB-500 blend ($59.95). All ship as lyophilized powder from US warehouses. Pricing is among the lowest we have recorded for research peptides, with Epithalon at under $30 per vial.

The consistent weakness across every PeptideGod product is documentation. None of the five product pages displays a Certificate of Analysis. None states the milligram amount per vial. Purity percentages are not listed. No testing laboratory is named. This makes it impossible to calculate price per milligram or verify peptide identity from the product page. We cannot compare PeptideGod on value without knowing what is in the vial. That blank is the reason their products rank below documented alternatives despite lower sticker prices.

Strengths: Lowest per-vial prices in our database. Broadest product range among peptide-only vendors. US shipping. Five products covering BPC-157, TB-500, MOTS-C and Epithalon.

Weaknesses: No COA on any product page. No milligram amounts disclosed. No stated purity or testing method. Price per milligram not calculable.

Best for: Researchers who prioritize low upfront cost and are willing to accept undocumented products.

• PeptideGod BPC-157 - $34.95
• PeptideGod TB-500 - $35.00
• PeptideGod MOTS-C - $49.95
• PeptideGod Epithalon - $29.95
• PeptideGod BPC-157+TB-500 Blend - $59.95

Real Peptides

Real Peptides sells HPLC-verified research peptides finished in the United States. Their BPC-157 10mg vial at $43.20 includes a lot-specific COA with HPLC purity stated at 99% or higher. Their MOTS-c 10mg vial matches the same price and includes HPLC COA documentation. Both products disclose milligram amounts, putting the price per milligram at $4.32/mg for each. Real Peptides also sells USP-grade bacteriostatic water at $4.80 per 10ml vial.

The product range is narrower than PeptideGod's. No TB-500, no Epithalon, no blend products. That is either a limitation or a focus, depending on perspective. What Real Peptides does stock comes with documentation that no other vendor in our database matches. Endotoxin screening results appear alongside the HPLC data on their COAs. For injectable research products, that screening matters.

Strengths: Lot-specific COA with HPLC verification on every product. Milligram amounts disclosed. Price per milligram calculable. Bacteriostatic water available. Endotoxin screening published.

Weaknesses: Narrower product range. Higher sticker price than PeptideGod ($43.20 vs. $34.95 for BPC-157). Fewer peptide options.

Best for: Researchers who require verified purity documentation and want to calculate exact concentrations after reconstitution.

• Real Peptides BPC-157 10mg - $43.20, ≥99% HPLC, lot COA
• Real Peptides MOTS-c 10mg - $43.20, HPLC COA
• Real Peptides Bacteriostatic Water 10ml - $4.80, USP-grade

Neurogan Health

Neurogan sells a GHK-Cu cream at $20.00 containing 1200mg of GHK-Cu at 2% concentration. The product has 34 user reviews averaging 4.9 stars on their product page. Neurogan operates in the skincare and wellness space rather than the research peptide market, which means their products are sold as cosmetics rather than laboratory chemicals. That distinction matters for regulatory classification and buyer expectations.

GHK-Cu is a tripeptide complexed with a copper ion. Unlike BPC-157 and TB-500, GHK-Cu has published human topical data showing increased collagen density and improved wound contraction. The topical route aligns with the published evidence, which gives Neurogan's product a stronger evidence basis than most peptide vials on the market. The $20.00 price point undercuts every other GHK-Cu product in our database by a wide margin.

Strengths: Lowest GHK-Cu price ($20.00). Concentration disclosed (2%, 1200mg). Strong user review average (4.9 stars, 34 reviews). Active ingredient has published human topical data.

Weaknesses: Single peptide product. No third-party COA published for the cream. Review sample size is small. Limited product information beyond concentration and reviews.

Best for: Buyers interested in topical GHK-Cu at a low price point with a disclosed concentration.

Scantifix

Scantifix sells a GHK-Cu topical product at $49.00. The product page provided limited specification data during our review. The concentration of GHK-Cu is not stated. The total amount of active ingredient is not disclosed. No user reviews were visible on the product page. The format is listed as a topical application, but specifics about whether it is a cream, serum or gel were not clearly differentiated.

At $49.00, Scantifix charges $29.00 more than Neurogan for a GHK-Cu topical product with less disclosed information. We could not determine from the product page whether the Scantifix product contains more active ingredient, uses a different delivery vehicle or offers any functional advantage over the cheaper alternative. Without concentration data or user feedback, there is little to evaluate beyond the price.

Strengths: Sells in the topical GHK-Cu category, which has published human evidence for its active ingredient.

Weaknesses: No concentration stated. No amount disclosed. No user reviews visible. $29.00 premium over Neurogan with no documented justification.

Best for: Buyers who have a specific reason to choose Scantifix over more transparent alternatives, though we could not identify one from the product page.

DoctorDerm

DoctorDerm sells a Copper Peptide Complex at $74.50 through a prescription model that includes a telehealth consultation. This positions DoctorDerm differently from other vendors in our database. The prescription pathway adds a medical professional to the purchasing process, which provides an oversight layer that over-the-counter products and research chemicals do not include.

The product page does not specify the GHK-Cu concentration or total amount. No user reviews were visible during our evaluation. The $74.50 price point is the highest for any GHK-Cu product in our database. Whether the consultation and prescription model justify the premium depends on how much value a buyer places on physician involvement. The active ingredient remains GHK-Cu, the same tripeptide available from Neurogan at $20.00 and Scantifix at $49.00.

Strengths: Prescription model includes telehealth consultation. Physician oversight may add safety value for topical application. Positioned as a medical-grade product.

Weaknesses: Highest price in the GHK-Cu category ($74.50). No concentration or amount disclosed. No visible user reviews. Active ingredient is the same compound available elsewhere at lower cost.

Best for: Buyers who want physician involvement in their GHK-Cu product selection and are willing to pay a premium for that consultation.

BiltRx

BiltRx is a brand that appeared in our research, but their website returned a 403 error during our data collection. A 403 error means the server actively refused to serve the page. This could indicate site maintenance, geographic restrictions, a paywall or a permanent change in business operations. We attempted access on multiple occasions and received the same result each time.

Because the product pages were inaccessible, we have no data on BiltRx's product range, pricing, testing documentation or shipping practices. We cannot evaluate what we cannot see. If BiltRx's website becomes accessible in the future, we will collect product data and add them to our comparison tables.

Strengths: Unknown. Product pages were inaccessible.

Weaknesses: Website returned 403 error. No product data available for evaluation. Buyer cannot browse or purchase if the site remains blocked.

Best for: Cannot recommend until product pages are accessible and evaluable.

Arc-1

Arc-1 appeared in our research with a price point of $199.99. That is the highest single-product price in our entire database by a significant margin. Beyond the price and brand name, limited product data was available during our evaluation. The product page did not provide the level of detail we require for a full assessment, including peptide identity, amount per unit, form factor and testing documentation.

At $199.99, Arc-1 costs roughly four times what Real Peptides charges for a documented 10mg BPC-157 vial and nearly six times PeptideGod's BPC-157 sticker price. Whether the price reflects a larger quantity, higher purity, a different compound entirely or simply a different market positioning could not be determined from the available data. We include Arc-1 here for completeness, but our evaluation is limited by the information gap.

Strengths: Present in the market. Pricing suggests possible premium positioning.

Weaknesses: $199.99 price point with limited product information available. Insufficient data to evaluate documentation, purity or value. Cannot calculate price per milligram.

Best for: Cannot recommend until more product data becomes available for evaluation.
