What B7-33 is

B7-33 is a single-chain peptide built from part of the B-chain of human relaxin-2, designed in Melbourne in 2016 to keep relaxin’s anti-fibrotic effects while being far cheaper and simpler to make. In rodents it reduced scarring in the heart, lung and kidney and improved blood vessel function, and unlike relaxin itself it did not promote prostate tumour growth in the one study that looked. No human trial of B7-33 has been published or registered, and the full-length relaxin drug it was derived from failed its own large heart failure trials.

Before you choose a B7-33 supplier

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.

For what B7-33 is and what published studies have found, see our B7-33 guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in Europe? and see all suppliers serving Europe.

Checking a B7-33 certificate of analysis

  1. The certificate names a laboratory you can find independently, and ideally one with no stake in the result.
  2. It carries a batch or lot number that matches the product page or the vial label, and a test date.
  3. It confirms identity by mass spectrometry, not only purity by HPLC. Purity alone does not show the vial contains B7-33.
  4. It includes the chromatogram and mass spectrum, not just a summary table.
  5. Where the laboratory offers online verification of its reports, the report number checks out.

Red flags

  • No certificates at all, or certificates available only “on request”.
  • The same certificate used for several products or several years of stock.
  • Payment only by cryptocurrency or bank transfer, with a discount for paying that way.
  • A price far below every other supplier on this page.
  • No company name, address or way to contact the business other than a web form.
  • Vials labelled only with a code rather than the product name and strength.

How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.

Vials, capsules and pre-mixed products

Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.

B7-33 in Europe: questions

Where can I buy B7-33 in Europe?

1 of the suppliers PepFinder tracks list B7-33 and are based in or ship to Europe. The highest rated are RCpeptides. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in Europe placed before those shipping in from abroad; nobody pays to be included or to rank higher.

What sizes is B7-33 sold in?

Suppliers on this page list B7-33 in 10mg. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.

Is it legal to buy B7-33 in Europe?

Across the EU, Iceland, Liechtenstein, Norway and Switzerland, a peptide that counts as a medicine cannot be placed on the market without an authorisation, and peptides sold as research products have none; penalties, possession rules and doping laws are set by each country and differ. Our page on whether peptides are legal in Europe sets out the rules with a link to every source. This is general information, not legal advice.

Can B7-33 be shipped to Europe?

Personal import rules are set nationally and differ widely: for example, Norway stops medicines sent by post, Austria says importing unauthorised peptide products is prohibited, and Switzerland allows one month's supply of a medicine for your own use but takes a zero-tolerance approach to doping substances. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.

How do I check a B7-33 supplier's test results?

Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for B7-33 from these suppliers, so check each supplier's own site.

How this list is built: suppliers appear because they list B7-33 on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
