Longevity research compounds

They are grouped by the questions researchers investigate, rather than by a shared mechanism. A listing here is not a claim that the vial slows ageing, extends life, repairs cells or treats a condition. “Longevity research” describes the subject area, not a demonstrated result for the supplied material.

What the studies look at

Ageing research uses many different measurements. A study might examine chromosome ends in cultured cells, chemical reactions involving NAD+, or changes in how an animal model handles glucose. These measurements answer different questions. A change in one does not establish a change in lifespan.

Epitalon, also written as Epithalon, is a synthetic peptide made from four amino acids, the building blocks of proteins. One area of research concerns telomeres: repeated DNA sequences at the ends of chromosomes. Telomerase is an enzyme that can add to those sequences.

Khavinson and colleagues studied Epithalon in cultured human fetal fibroblasts, cells associated with connective tissue. They reported telomerase activity and telomere elongation under the study conditions. Although the cells were human, this was a laboratory cell model, not a trial showing an effect in people. It did not establish longer human life or test an EU Peptides vial.

NAD+ means nicotinamide adenine dinucleotide in its oxidised form. It participates in reactions that transfer electrons, a central part of cellular energy metabolism. It is also used by enzymes involved in processes such as protein regulation and responses to DNA damage.

NAD+ research therefore asks different questions from Epitalon research. Scientists examine how cells make, use and recycle NAD+, and how its availability relates to enzyme activity. Cantó and colleagues review these connections between energy metabolism, mitochondria and the cell nucleus. This is a review of NAD+ biology, not evidence that a supplied NAD+ vial changes ageing.

MOTS-c is a peptide of 16 amino acids whose coding sequence was identified within mitochondrial DNA. Mitochondria participate in energy production and communication within cells. The term “mitochondrial-derived peptide” describes this biological origin; it does not mean the vial contains mitochondria.

Lee and colleagues investigated MOTS-c in cell systems and mice. Their experiments examined glucose use, insulin sensitivity and AMPK, an enzyme involved in coordinating cellular energy use. They linked changes in cellular metabolic pathways with AMPK activation. These experimental findings concern the tested models and materials, not outcomes in people or verified activity of the vial.

The energy and glucose questions also overlap with metabolic research. That connection helps organise the catalogue; it does not make compounds from the two categories interchangeable.

Compare the three compounds

The compound name identifies the research material. The amount stated for a vial identifies its supplied quantity. Neither establishes batch purity or shows that the material will reproduce a published experiment.

A telomere measurement for Epitalon cannot describe NAD+ chemistry. An AMPK result for MOTS-c cannot establish Epitalon activity. Keeping the compound, model and measurement together makes the research easier to compare without turning separate findings into a general “anti-ageing” claim.

Certificate and lot

Batch certificates are not yet available, so no batch-specific purity result is stated here.

The listing rule is that a batch will be listed for sale only after its certificate has been checked. The lot number on the file must match the lot number on the vial. If the numbers are missing or do not match, that batch is not listed. A report for another lot of the same compound is not a substitute.

The acceptance requirement is at least 99% purity by HPLC. This is the listing threshold, not a measured result for an uncertified vial. The figure published for a batch must be the figure on that batch’s certificate.

HPLC separates components in the tested sample and assesses purity under the stated method. Where the certificate includes mass spectrometry, that result is also reviewed for evidence supporting identity. Neither test demonstrates telomere changes, metabolic activity or an effect on lifespan.
