Practical guides and research insights for anyone working with peptides, from beginners to experienced researchers.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
What a 99%+ HPLC purity figure on a peptide COA does and does not tell you, how the chromatogram is read, and what UK labs should check first.
What BPC-157 is as a listed laboratory material: sequence, synthetic origin, salt and format variants, reported stability, and what the published evidence base does and does not establish.
GHK-Cu is a copper-bound tripeptide, and "copper peptide" is a generic term covering several distinct molecules. A non-clinical reference on identity, the copper complex and evidence tiers.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
CJC-1295 exists in DAC and non-DAC forms, and Ipamorelin acts on a different receptor entirely. A non-clinical reference on which molecule is which.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
TB-500 is a synthetic fragment, not the full-length thymosin beta-4 protein. A non-clinical reference on why that distinction governs how the literature on it can be read.
A line-by-line walk through a peptide certificate of analysis: HPLC purity, mass spec identity, batch and date fields, and the signs of a fake COA.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
Sterile water and bacteriostatic water are different reagents, and the difference is a preservative. A non-clinical reference on reagent identity and labelling.
The most common scam is not a fake product. It is a real product with less peptide in the vial than the label claims, and it is invisible without testing.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
A non-clinical reference on catalogue identity, analytical documentation and the limits of what published evidence and batch testing establish.
BPC-157 and TB-500 are two separately listed research materials, and one is a fragment rather than a full-length protein. A non-clinical reference on how their identities, blend presentation and evidence bases differ.
What UK research peptides actually cost, why the same compound is priced differently across sellers, and how our current catalogue prices break down by category, format and HPLC purity.
What BPC-157 costs in the UK, the £/mg on our 10mg vial, why cross-compound price comparisons are misleading, and how to check a batch certificate against the price.
Retatrutide prices across our 10mg, 20mg and 30mg vials, the full cost-per-mg ladder, and why the larger vial is the genuinely competitive format rather than the smaller one.
What Tirzepatide costs in the UK, the £/mg on our 10mg vial, how it compares to Retatrutide's per-mg pricing, and how to verify the batch certificate behind the price.
TB-500's UK list price and £/mg, why it is currently shown for reference rather than as a live buyable price, and how it is priced relative to BPC-157.
What GHK-Cu costs in the UK, the £/mg on our 50mg vial, why the larger fill puts it among the cheapest catalogue entries per mg, and how to verify the batch behind the price.
What NAD+ costs in the UK, the £/mg on our 100mg vial, why it is priced and formatted differently to the peptides in the rest of the catalogue, and how to verify the price.
What our CJC-1295 (no DAC) + Ipamorelin blend costs in the UK, how its £/mg compares to buying Ipamorelin and Tesamorelin separately, and how to verify the price.
What MOTS-c is, how it is classified, its development status, and what published research does and does not establish.
What KLOW Research Blend contains, how its 80mg figure is documented, and what published research does and does not establish.
What tesamorelin is, how it is classified, its development status, and what published research does and does not establish.
How Semax and Selank differ on structure, origin, classification and evidence tier, and where a direct comparison breaks down.
What retatrutide is, how it is classified, where its development stands, and what published research does and does not establish.
Which adverse events were reported in published retatrutide trials, how often, and what those trials can and cannot tell you.
What GHK-Cu is, how copper binds to the GHK tripeptide, how it is classified, and what published research does and does not establish.
What Selank is, where it comes from, how it is classified, and what published research does and does not establish.
What "CJC-1295 no DAC" means, how it differs from the DAC form, and how to check which one a certificate describes.
What a retatrutide research vial contains, what 10mg looks like, and how to check a vial against its batch certificate.
