Peptide Supplements: Ranked Picks for Research

Peptide supplements is a term that gets used loosely online. Lyophilized vials labeled "for research use only" are not supplements. Topical creams with published human skin data are closer to that category but still sit outside FDA supplement classification. We reviewed the actual products available from seven vendors, checked documentation on each product page and ranked them by transparency, not by marketing claims or social media presence.

Peptide God Real Peptides Neurogan Vial Topical

Ranked Peptide Products for Research

This table sorts every product in our database by documentation quality first, then value. Products with published COA data and disclosed amounts rank above those without, regardless of price. We include both injectable-format vials and topical products because the peptide supplement market spans both categories.

Peptide God Products

Product Range and Pricing

PeptideGod sells five peptide products ranging from $29.95 to $59.95 per vial. The lineup includes BPC-157, TB-500, MOTS-C, Epithalon and a BPC-157 + TB-500 blend. All are shipped as lyophilized powder from US-based warehouses. Pricing is aggressive. PeptideGod's Epithalon at $29.95 is the cheapest vial in our database.

The documentation problem is consistent across every PeptideGod product. None of the five product pages displays a COA. None states a milligram amount per vial. None mentions purity testing or the name of a testing laboratory. We cannot calculate price per milligram for any PeptideGod product. That is five products with undisclosed amounts from one vendor. It may be that PeptideGod tests every batch rigorously. But if they do, we have no evidence of it from what their website shows.

Real Peptides Products

Documentation and Pricing

Real Peptides takes a different approach. Their BPC-157 10mg vial at $43.20 comes with a published lot-specific COA showing HPLC purity of 99% or higher. Their MOTS-c 10mg vial matches the same price point and includes HPLC COA documentation. Both products list milligram amounts, enabling a straightforward price per milligram calculation: $4.32/mg for each.

Real Peptides also sells bacteriostatic water at $4.80 for a 10ml USP-grade vial. That makes them a one-stop source for reconstitution supplies. The product range is narrower than PeptideGod's. No TB-500, no Epithalon, no blends. Fewer products, better documentation. Whether that tradeoff matters depends on what you prioritize.

One practical advantage of disclosed vial sizes: concentration can be calculated before purchase. A researcher can decide how much bacteriostatic water to use, predict the concentration per draw and plan their protocol accordingly. With undisclosed vial sizes, that planning is impossible. Our reconstitution calculator automates the math for any known vial size.

Neurogan Health Products

GHK-Cu Cream

Neurogan sells a GHK-Cu cream at $20.00 with 1200mg of GHK-Cu at 2% concentration. The product has 34 user reviews averaging 4.9 stars. That review score is high, though the sample size is small. GHK-Cu is a tripeptide with published human topical data, which places it in a different evidence tier than most research peptides. We cover that distinction on our research peptides page.

At $20.00, Neurogan's cream costs less than half of Scantifix's GHK-Cu topical ($49.00) and roughly a quarter of DoctorDerm's prescription copper complex ($74.50). The concentration disclosure and user reviews give Neurogan a transparency advantage over both competitors in this category.

Lyophilized Vial Products

Price per Milligram Comparison

Price per milligram is the only honest way to compare vial products. Sticker price comparisons are misleading when vial sizes differ or when one vendor refuses to disclose the amount. The table below includes only products where price per milligram can be calculated.

Only two products qualify. Every PeptideGod vial is absent from this table because none disclose milligram amounts. That is not a ranking decision we made. It is a data gap the vendor created. If PeptideGod published vial sizes tomorrow, the table would expand. Until then, we can only rank what we can measure.

For perspective on what the $4.32/mg figure means: a 10mg vial reconstituted with 2ml of bacteriostatic water yields 500 mcg per 0.1ml draw. That gives 20 draws from a single vial. The bacteriostatic water adds $4.80 to the total cost, bringing the per-vial expense to $48.00. Research protocols in published studies typically use microgram-range amounts, so a single vial covers multiple sessions depending on the protocol. Our dosage data page lists the amounts used in published animal studies.

Topical Peptide Products

GHK-Cu Topical Comparison

The price spread across GHK-Cu topical products is substantial. Neurogan at $20.00 is the only product disclosing both amount and concentration. Scantifix charges $49.00 but does not state the GHK-Cu concentration on the product page. DoctorDerm's $74.50 copper complex requires a prescription through their telehealth service. Whether the consultation adds clinical value beyond what a $20.00 cream provides is a question we cannot answer from product pages alone.

Supplements vs. Research Chemicals: The Label Problem

Calling lyophilized peptide vials "supplements" is inaccurate. Under the Dietary Supplement Health and Education Act (DSHEA), supplements must contain recognized dietary ingredients and follow specific labeling rules. BPC-157, TB-500 and MOTS-C are not recognized dietary ingredients. The FDA has issued warning letters to vendors who marketed peptides as supplements. The correct label is "research chemical" or "laboratory reagent." We use the term "peptide supplements" in this article because that is what people search for. But accuracy matters, and the products reviewed here are not supplements by any regulatory definition.

Topical GHK-Cu products are closer to cosmetics under FDA definitions, depending on the claims made. Neurogan's cream is sold as a skincare product, not a research chemical. That puts it in a different category than the vials discussed above. Our best peptides page covers the full comparison across categories.
