MOTS-c: The Mitochondrial-Derived Peptide Rewriting Metabolism Research
A 16-amino-acid peptide encoded inside mitochondrial DNA is reshaping how researchers think about AMPK signaling, insulin sensitivity, and the cellular response to exercise.
Tesamorelin: A GHRH Analogue With the Strongest Clinical Track Record
Of all the growth-hormone-releasing peptides used in research, tesamorelin is unique: it has cleared full FDA approval and carries human trial data measured by MRI, not anecdote.
CJC-1295 (no DAC) + Ipamorelin: Why Researchers Pair These Two Peptides
GHRH analogues and GH secretagogues work on different pituitary receptors. The CJC-1295 + Ipamorelin combination is studied because the two together generate a larger, cleaner GH pulse than either alone.
Retatrutide: The Triple-Receptor Agonist Behind 24% Weight Loss in Phase 2
GLP-1 alone reshaped obesity medicine. Eli Lilly's retatrutide activates three metabolic receptors at once, and the published Phase 2 results are among the most striking ever reported in this space.
BPC-157 + TB-500: Two Peptides Studied for Their Effects on Tissue Repair
BPC-157 acts in the gastrointestinal tract and on tendon-cell biology in animal models. TB-500, a fragment of thymosin β4, has been characterized for actin sequestration and angiogenesis. Together they are one of the most discussed and least clinically validated combinations in peptide research.
GHK-Cu: Forty Years of Research on a Three-Amino-Acid Copper Peptide
Glycyl-L-histidyl-L-lysine binds copper(II) with extraordinary affinity. Pickart's original 1973 work has compounded into one of the most-studied small peptides in dermatology, wound repair, and gene-expression research.
What “99% Purity” Actually Means for a Research Peptide
Purity is the headline number on every peptide listing — but 99% purity and 99% peptide content are different things, measured differently. Here is what the number does and doesn’t tell you.
Third-Party vs In-House Peptide Testing: Why It Matters
Both can produce a COA. Only one removes the conflict of interest. Here is why independent, third-party testing is the higher standard of evidence for a research peptide’s purity and identity.
How to Spot a Fake or Recycled Certificate of Analysis
A COA is only worth as much as its authenticity. These are the concrete tells that separate a genuine, batch-specific lab report from a recycled image or a fabricated one.
What to Look For in a Research Peptide Supplier
