Are Peptides Legal in the UK? The Actual Legal Position
The honest answer is that it depends entirely on what the peptide is sold for, not what the peptide is. Buying and possessing research peptides for laboratory work is lawful in the UK. Supplying them for human consumption is a criminal offence, and that distinction is the whole of the law here.

BPC-157 Research Guide: What Scientists Need to Know
BPC-157 is one of the most widely studied research peptides in preclinical science. Learn about its molecular structure, stability, research applications, and laboratory handling.

Tesamorelin vs CJC-1295: GH Secretagogue Research Comparison
Tesamorelin is a stabilised full-length GHRH analogue. CJC-1295 is a truncated GHRH(1-29) analogue with optional DAC technology. Comparison of mechanism, pulsatility, and research applications.

Melanotan I vs Melanotan II: Receptor Selectivity Comparison
Melanotan I and Melanotan II differ in receptor selectivity. One acts narrowly at MC1R, the other broadly across the melanocortin receptor family. A research comparison of mechanism and applications.

Semax vs Selank: Russian Nootropic Peptide Comparison
Semax and Selank are both Russian-developed heptapeptides studied in cognitive and anxiolytic research, but they derive from different parent hormones and act through different pathways.

PT-141 (Bremelanotide): Melanocortin Receptor Research Guide
PT-141 (Bremelanotide) is a cyclic heptapeptide derived from Melanotan II, modified to remove MC1R activity and concentrate action at the central MC3R and MC4R receptors.

MOTS-C: Mitochondrial-Derived Peptide Research Guide
MOTS-C is a short peptide encoded within mitochondrial DNA. Discovered in 2015, it has become a central tool in research on AMPK signalling, metabolic homeostasis, and mitochondrial-nuclear crosstalk.

IGF-1 LR3 Research Guide: Mechanism, Pharmacology, Laboratory Use
IGF-1 LR3 is a long-acting analogue of insulin-like growth factor 1 with an Arg substitution at position 3 and a 13-amino-acid N-terminal extension. Extended half-life and reduced IGFBP binding make it a widely used tool in cell proliferation and myogenesis research.

DSIP (Delta Sleep-Inducing Peptide): Evidence Review
DSIP is a 9-amino-acid peptide first isolated from rabbit cerebral venous blood in 1977. Despite five decades of research, its receptor and mechanism remain uncharacterised. A research guide with an honest review of the evidence base.

CJC-1295 With DAC vs Without DAC: Research Comparison
CJC-1295 exists in two distinct research forms. The 'no DAC' variant produces a pulsatile GH research model with a half-life of around 30 minutes. The 'DAC' variant binds albumin covalently and extends half-life to multiple days. The receptor mechanism is identical; the pharmacokinetics are not.

KPV: Anti-Inflammatory Tripeptide Research Guide
KPV is a tripeptide (lysine-proline-valine) derived from the C-terminal of alpha-MSH. Studied for anti-inflammatory effects in gastrointestinal research models, with NF-kB pathway modulation as the principal proposed mechanism.
