Study Summaries, Trial Reviews and Mechanism Breakdowns

RT vs TZ: What the Trial Data Shows

RT adds glucagon receptor agonism to the GIP/GLP-1 dual mechanism of TZ.

TZ vs SM: The 2025 obesity head-to-head trial Head-to-Head

This is the only major incretin comparison supported by direct head-to-head trials. SM, however, has the longer cardiovascular outcome record.

Cagrilintide vs SM: Amylin and Incretin Compared

Cagrilintide is a long-acting amylin analogue; SM is a GLP-1 receptor agonist. They act through different satiety pathways, which is why the interesting research question has been combination rather than substitution — the CagriSema programme tests exactly that.

BPC-157 vs TB-500: Two Preclinical Repair Peptides Compared

BPC-157 and TB-500 are the two peptides most often discussed for tissue repair research, and they work through different mechanisms — angiogenic and growth-factor signalling versus actin sequestration and cell migration. Both share the same critical limitation: essentially all supporting evidence is preclinical, from rodent models, with no controlled human trials.

MOTS-c vs SS-31: Two Approaches to Mitochondrial Research

MOTS-c and SS-31 both relate to mitochondrial function but sit at very different stages. MOTS-c is an endogenous mitochondrial-derived peptide acting as a metabolic signal; SS-31 (elamipretide) is a synthetic cardiolipin-binding compound that has completed multiple human clinical trials, with mixed primary endpoint results.
