Research guide
Research guides
Plain-language guides to the compounds people search for most: what they are, how they are studied, how to store and check them. With sources, for laboratory research only.
Retatrutide: what the research shows
Retatrutide is an investigational peptide that acts on three hormone receptors at once: GIP, GLP-1 and glucagon. What it is, what the published trials measured, what is still unknown and where it stands with regulators in October 2026.
Tirzepatide: what the research shows
Tirzepatide activates two gut-hormone receptors, GIP and GLP-1. How it was tested in the SURPASS and SURMOUNT trials, what the trials found about safety, its regulatory status and how research material differs from the approved medicine.
Semaglutide: what the research shows
Semaglutide is a long-acting analogue of the gut hormone GLP-1. What it is, the large trials behind it (SUSTAIN-6, STEP 1, SELECT), the safety findings, its regulatory status and why the salt form of a batch matters.
BPC-157: what the research shows
BPC-157 is a 15-amino-acid peptide studied mostly in rodent models of tendon, ligament, muscle and gut injury. What it is, what the evidence covers, what is missing in humans, and its status in sport.
TB-500 and thymosin beta-4: what the research shows
TB-500 is the name under which products related to thymosin beta-4, a natural repair peptide, are sold. What thymosin beta-4 does in cells and animal models, what TB-500 actually contained when it was analysed, the human data and its status in sport.
GHK-Cu: what the research shows
GHK-Cu is the copper complex of GHK, a three-amino-acid peptide found in human plasma, saliva and urine. What it is, what research on tissue remodelling, skin and gene expression covers, the limits of that evidence and how to check a batch.
Cagrilintide: what the research shows
Cagrilintide is an investigational long-acting analogue of amylin, a pancreatic hormone linked to satiety. How it was designed, what the trials alone and together with semaglutide measured, the safety findings and its regulatory status in October 2026.
MOTS-c: what the research shows
MOTS-c is a 16-amino-acid peptide encoded not in the cell nucleus but in mitochondrial DNA. What it is, what studies in cells and mice found about metabolism, muscle and ageing, what human data exist and its status in sport.
