Melanotan-1 vs Melanotan-2: Selectivity and Receptors Compared
The names suggest a compound and its sequel. In fact one is MC1R selective and an approved medicine, the other binds half the melanocortin family.
Retatrutide vs Tirzepatide: Triple and Dual Agonism Compared
One receptor separates them. Tirzepatide binds two, retatrutide binds three, and that third one changes what the compound is trying to do.
Is BPC-157 Legal in the UK? What the Law Actually Says
Not a controlled substance, but not an approved medicine either. BPC-157 sits in a third category under UK law, and that distinction is the whole answer.
How to Read a Peptide Certificate of Analysis
A purity figure on its own proves very little. Here is what HPLC and mass spectrometry each tell you, and what a certificate has to show to mean anything.
How Long Do Peptides Last? Storage, Shelf Life and Stability
A sealed vial of powder lasts years. The same vial with water in it lasts weeks. Understanding why is most of what peptide storage comes down to.
SNAP-8 Peptide UK Guide: Acetyl Octapeptide-3 Research
Botulinum toxin cuts the machinery that releases neurotransmitter. SNAP-8 impersonates a piece of it instead. Same target, entirely different approach.
Oxytocin Peptide UK Guide: Structure, Research and Study Data
The first peptide hormone anyone ever synthesised, and the result that proved these molecules could be built rather than only extracted. Nine amino acids, one disulfide bond.
AHK-Cu Peptide UK Guide: Copper Tripeptide-3 Research
One amino acid separates AHK-Cu from GHK-Cu, and that single substitution redirects a copper peptide from skin remodelling to the base of the hair follicle.
