§4Compounds assessed

Compounds the Institute assesses in this indication, with the class of each and its overall certainty. A compound appears here whether or not the evidence supports its use, because recording that a compound has been studied and found wanting is as much part of the assessment as recording that one has not.

  • Small-molecule nicotinamide N-methyltransferase inhibitor0 contributing trialsfull monograph

    No human trial identified — —

    Very low
  • Growth-hormone-releasing hormone analogue with albumin-binding drug affinity complex0 contributing trialsfull monograph

    No randomised human evidence identified — No trial supports any ageing or healthspan claim.

    Very low
  • Synthetic tetrapeptide1 contributing trialfull monograph

    Russian observational and small controlled reports describe mortality and functional differences over multi-year follow-up — The Institute assesses these reports as not permitting a certainty rating above very low. It records that mortality claims of this…

    Very low
  • Copper(II)-complexed tripeptide0 contributing trialsfull monograph

    No randomised human evidence for any systemic ageing endpoint — The declining-with-age plasma concentration is an observation, not evidence of an intervention effect.

    Very low
  • Endogenous tripeptide thiol antioxidant0 contributing trialsfull monograph

    No randomised evidence for any ageing endpoint — —

    Very low
  • Mitochondrial-derived 16-residue peptide0 contributing trialsfull monograph

    No randomised controlled human trial identified — Observational associations between endogenous MOTS-c concentration and metabolic phenotype exist; these are associations, not intervention evidence.

    Very low
  • Endogenous pyridine dinucleotide coenzyme0 contributing trialsfull monograph

    No randomised controlled human trial of administered NAD+ on any ageing endpoint identified — Trials of the oral precursors nicotinamide riboside and nicotinamide mononucleotide exist and report raised blood NAD+ concentrations with limited functional effect…

    Very low
  • Growth-hormone-releasing hormone fragment analogue0 contributing trialsfull monograph

    No randomised human evidence identified — Marketing claims in this indication are not supported by any trial the Institute has been able to locate.

    Very low
  • Thymic peptide extract of undefined composition0 contributing trialsfull monograph

    No assessable evidence identified — —
