The UK research peptide market has grown considerably over the past few years, and with that growth has come a predictable problem: a substantial variation in quality, documentation, and transparency between suppliers. When all you can see online is a product page with a purity claim and a price, making a well-informed sourcing decision is […]
Growth hormone secretagogues — GHRH analogues like CJC-1295 and Sermorelin, and ghrelin receptor agonists like Ipamorelin and GHRP-2 — are frequently discussed in the same breath as recombinant human growth hormone (rhGH). Both categories produce elevated GH levels. But the mechanism by which they do so is fundamentally different, and that difference has significant implications […]
A well-produced Certificate of Analysis for a research peptide includes at minimum two analytical results: an HPLC purity figure and mass spectrometry identity confirmation. Most researchers know that higher purity is better and that a matching molecular weight is a good sign — but the actual mechanics of what each test measures, and crucially what […]
