The shop carries three brands of lyophilised research peptides: Bio-Peptide, Genheal and Nouveaux Ltd. It is the same type of product, the same form and the same intended use for laboratory research. There is no public, independent data comparing their purity, and the site does not publish details about the companies behind the brands. In practice the brands differ in what you can see in the catalogue: the range of items, vial sizes and price. What actually protects a buyer is verifying the hologram and code on each vial, plus caution towards products from this market generally.
What do all three brands have in common?
The common ground is wide. All three are lyophilised peptides sold as research reagents rather than as medicines, so none of these brands offers a product with medicinal approval. All use the same mechanism for confirming authenticity: after purchase you scratch off the hologram, choose the brand on the authenticity page and enter the code on that manufacturer’s site. Bio-Peptide, Genheal and Nouveaux Ltd each have their own verification page, listed on the check your product page. Storage and reconstitution are the same regardless of brand and are described in the articles on storing peptides and on reconstitution with bacteriostatic water.
It is worth knowing what such a code confirms and what it does not. A positive result means the number on the hologram matches the record the manufacturer keeps for released batches. That guards against simple counterfeiting of the packaging. It is not an independent measurement of what is in the vial, because the verification is run by the same company that released the product.
How do they differ in practice?
The differences you can check concern the catalogue itself.
- Vial size. Nouveaux Ltd more often offers larger single vials, for example BPC-157 at 20 mg, sermorelin at 10 mg, CJC-1295 at 10 mg, PEG-MGF at 10 mg or follistatin 344 at 2 mg. Bio-Peptide and Genheal appear more often in smaller sizes, of the order of 5 mg or 1 mg.
- Exclusive items. Some peptides are carried by one brand only. MOTS-c is stocked as Bio-Peptide alone, while tesamorelin and the ready-made BPC-157 with TB-500 mix come only from Genheal. DES(1-3) IGF-1 is carried by Bio-Peptide and Genheal, but not by Nouveaux Ltd.
- Shared range. The most popular peptides, such as BPC-157, TB-500, CJC-1295, Mod GRF 1-29, PEG-MGF and IGF-1 LR3, are available across all three brands.
Price differs between brands and between sizes of the same peptide. Current rates are shown on each product page in the shop, and the brands themselves are listed on the manufacturers page.
Does the brand tell you anything about quality?
A brand name is not an indicator of peptide purity. In independent analyses of grey-market products, contamination or mislabelling affects about 30 per cent of the samples tested. Neither the shop nor any public source provides independent purity data broken down by these three brands. What lowers the risk is a specific document: a certificate of analysis for the given batch, stating purity by HPLC and confirming the mass of the molecule, issued by an independent laboratory. A brand that cannot show such a certificate for the batch you received is giving you no purity data at all. How to tell a credible product from a counterfeit is explained in the article on recognising fake peptides.
How to choose between the brands
Base the choice on four things you can check:
- whether the peptide you want is available from more than one brand at all;
- whether the vial size matches your planned use, because a large vial stays in solution longer, and that works against the stability of the peptide;
- the price per milligram of the amount you need;
- whether the seller can show a current certificate of analysis for that batch.
The prestige of a name is not a criterion, because there is no public basis for ranking these three brands on quality.
Frequently asked questions
Which peptide brand is best: Bio-Peptide, Genheal or Nouveaux Ltd?
There is no public, independent data that would allow them to be ranked on quality. They differ in range, vial size and price, not in documented purity.
Are all three brands research peptides?
Yes. None of them is an approved medicine. All are sold as reagents for laboratory research.
How do I check whether a vial is genuine?
After purchase you scratch off the hologram, choose the brand on the authenticity page and enter the code on that brand’s site. Bio-Peptide, Genheal and Nouveaux Ltd have separate verification pages.
Does a more expensive brand mean a purer peptide?
Not necessarily. Price also depends on vial size and on the item’s place in the range. Purity is shown by a certificate of analysis from an independent laboratory, not by price or by the name on the label.
Where this information comes from
The brand line-up, the vial sizes and which items are exclusive to a single brand were read from the shop catalogue on 8 September 2026. The verification procedure comes from the authenticity page and the manufacturers’ own verification sites. The figure of about 30 per cent of grey-market samples with contamination or mislabelling comes from published independent analyses of such products.
