Research Notes

PT-141: A Central Mechanism, Not a Vascular One
PT-141 acts on melanocortin receptors in the central nervous system, which is what distinguishes it from vasodilatory compounds in the research literature. Read more...
Tesamorelin and IGF-1 LR3: Two Points on the Growth Hormone Axis
One peptide acts upstream at the pituitary, the other downstream as an IGF-1 analogue. Why the distinction matters in research design. Read more...
How to Read a Certificate of Analysis
HPLC purity, mass spectrometry, water content and the fields that matter on a peptide COA — including how to spot a document that proves nothing. Read more...
Peptide Reconstitution: Water, Aliquoting and Storage
Bacteriostatic versus sterile water, how to add diluent without damaging the peptide, aliquoting, and how long reconstituted material lasts. Read more...
Epitalon and MOTS-c: Longevity Peptide Research
One peptide from the pineal gland, one encoded in mitochondrial DNA. Both studied in relation to cellular ageing, from different directions. Read more...
Semax and Selank: Nootropic Peptide Research
Two peptides developed in Russia and studied for neurotrophic signalling, attention and anxiolytic activity. What the literature describes. Read more...
GHK-Cu: The Copper Peptide in Skin and Hair Research
GHK-Cu is a naturally occurring copper-binding tripeptide whose plasma concentration declines with age. An overview of the research literature. Read more...
BPC-157 and TB-500: Tissue Repair Research
Two peptides frequently studied together in tissue-repair literature, and why their described mechanisms are distinct. Read more...
Retatrutide: What the Research Describes
A research overview of retatrutide, the triple GLP-1, GIP and glucagon receptor agonist, and how it differs from single and dual agonists. Read more...
How to Verify Peptide Authenticity
Seals, lot numbers, certificates of analysis and appearance checks. A practical method for verifying research peptides rather than trusting a label. Read more...
Storing Peptides in Egypt's Climate
Cairo summers reach 40 degrees. Practical guidance on cold chain, freezer storage, reconstitution and transport for research peptides in Egypt. Read more...
Buying Peptides in Egypt: Sourcing, Storage and Verification
What to check before buying research peptides in Egypt: provenance, cold chain, seal integrity, lot numbers and certificates of analysis. Read more...
