What B7-33 is
B7-33 is a single-chain peptide analogue of relaxin, engineered to retain the anti-fibrotic signalling of the parent hormone without its full receptor activity profile. Published work covers cardiac and renal fibrosis models and preeclampsia research.
It is a comparatively recent research molecule with a coherent mechanism and a thin dataset, which is a common profile for compounds priced in this range.
What the evidence base looks like
The published record is early: a coherent mechanism, a handful of encouraging studies, and very little independent replication at human scale.
Our library records roughly 21 relevant publications for B7-33 and grades the evidence as emerging. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on B7-33
Correct disulfide bridging determines whether the molecule folds into an active form, and few certificates address it.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 10mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 10mg vial is £34.90, against a market median nearer £50. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
