How metabolic research moved from a single receptor to two to three — and what each added hormone receptor changed in the preclinical and trial evidence. A mechanism comparison, with the research-use-only distinctions kept strict.
Two synthetic peptides that are almost always studied as a pair: one mimics ghrelin, the other mimics GHRH. A research primer on how each knocks on the growth-hormone axis — and what the preclinical record actually shows.
5-Amino-1MQ is a small-molecule inhibitor of the enzyme NNMT, studied in cells and obese mice for its effects on the NAD+ and methylation economy of fat tissue. Here is what the preclinical record actually shows — and where it stops.
A four-letter peptide carries a decades-old case of mistaken identity. A 2026 re-examination argues the famous dose was never Epitalon’s at all — and that the difference is a lesson in why what is in the vial matters more than the label on it.
Retatrutide (LY3437943) is a single engineered peptide built to pull three metabolic levers at once. Here is what the science actually shows — and why a research-grade compound is not the same thing as an approved medicine.
