What Is NAD+? Cellular Energy, Sirtuins and the Research Record
A plain-language guide to NAD+: what it does in redox metabolism and signaling, why it declines with age, and what human and animal studies have shown.
Understanding Peptide Purity: What 99% Does and Doesn’t Tell You
A purity figure is a chromatographic ratio, not a statement about everything in the vial. What the number measures, what it leaves out and how to read it.
GHK-Cu: What the Copper-Peptide Literature Shows
A plasma tripeptide found in 1973, a copper complex, and fifty years of fibroblast and wound studies. What the GHK-Cu record supports and what it leaves open.
What Are GLP-1 Peptides? Incretin Biology for Researchers
The biology behind GLP-1: where it comes from, what it does, why the native hormone lasts two minutes, and how synthetic analogues were built to last a week.
Tesamorelin: What the Clinical and Preclinical Literature Shows
Tesamorelin is a stabilized GHRH analogue and the active ingredient of Egrifta. Its phase 3 trials, liver and cognition studies, and evidence limits.
What Is HPLC and How Does It Measure Peptide Purity?
HPLC separates a peptide from its impurities on a column and reports the result as a chromatogram. Here is how it works and how to read one on a COA.
MOTS-c: A Mitochondrial-Derived Peptide in Metabolic Research
What the literature shows about MOTS-c, a 16-amino-acid peptide encoded in mitochondrial DNA: AMPK signaling, mouse exercise studies and one small human trial.
BPC-157 vs. TB-500: Different Mechanisms, Overlapping Research Interest
One is a gastric peptide acting through VEGFR2 and nitric oxide; the other is a fragment of an actin-binding protein. A side-by-side reading of the evidence.
Research Peptides Explained: What “Research Use Only” Actually Means
Where the RUO label comes from, how FDA views unapproved drugs and intended use, and why research peptide suppliers ask for researcher affirmations.
CJC-1295 and Ipamorelin: Why Researchers Study Them Together
A GHRH analog and a ghrelin-receptor agonist act on two different pituitary receptors. The literature explains why that pairing draws research interest.
NMN vs. NR vs. NAD+: Precursors and the Direct Molecule Compared
How nicotinamide mononucleotide, nicotinamide riboside and NAD+ itself differ in structure, uptake, human evidence and regulatory status.
Selank vs. Semax: Two Russian Neuropeptides Compared
Selank and Semax share a laboratory of origin and a stabilizing tail but not a mechanism. A side-by-side reading of the research on each.
