GLP-1 and Mitochondria: A 2026 Review Maps the Axis
GLP-1 drugs touch mitochondrial biogenesis, dynamics and mitophagy. A 2026 Aging Cell review asks how much of that is the receptor, not weight loss.
MOTS-c Neutralised MRSA in Mice: A 2026 eLife Report
MOTS-c is not only a metabolic peptide. An eLife paper reports it kills bacteria directly and reprograms monocytes, making it the first mitochondrial HDP.
Thymosin Beta-4 in Colitis: What a 2026 Mouse Study Found
Thymosin beta-4 turns up in gut inflammation, not just tissue repair. A 2026 mouse study links it to a receptor nobody associated with the peptide before.
GEP44: A 3-in-1 Peptide Designed Around Side Effects
GEP44 is a chimeric peptide built from GLP-1, exendin-4 and PYY3-36. Its design target was tolerability, not more weight loss. All data are preclinical.
GLP-1 Receptor Agonists: One Method Now Identifies 9
GLP-1 receptor agonists are hard to tell apart analytically. A validated LC-HRMS method now identifies and quantifies nine of them in one 20 minute run.
MOTS-c and the Overlooked Microproteins: What a 2026 Review Adds
A narrative review in Epigenomics maps the microproteins encoded by short open reading frames, and names the MOTS-c peptide among the handful that are well studied. It is a useful reframing of a compound usually discussed on its own.
KPV Peptide Research Moves Into Metabolism: First Adipocyte Study Reported
KPV peptide work has centred on inflammation for nearly two decades. A new Tissue Cell paper reports the first look at what the tripeptide does to fat cell differentiation, in cultured cells and in a mouse model.
GHK-Cu Skin Research: Two New 2026 Papers, and Why Their Design Differs
Two GHK-Cu papers published in 2026 report anti-inflammatory and skin findings. One comes from a cosmetics company's own R&D centre, the other from a university lab, and neither tested the peptide on its own.
BPC-157 and TB-500 Tendon Healing: What a New Rat Study Reports
In a rat Achilles tendon model, the authors report that only TB-500 reached biomechanical significance, and that pairing it with BPC-157 added no measurable advantage over either peptide alone.
What a New UCLA Review Says About Six Popular Research Peptides
A scoping review published online on 11 August 2026 in The American Journal of Sports Medicine takes a systematic look at the evidence ...
