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.

How to Read a Peptide COA: HPLC and Mass Spec Explained

A Certificate of Analysis is only useful if you can read it. Here is exactly what each section of a peptide COA means — HPLC purity, mass spectrometry identity, and the lines most buyers skip.

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.
