Start with the essentials
The Complete Guide to Retatrutide
A researcher's guide to GLP-3 RT — Peptora's designation for Retatrutide — covering its triple-receptor mechanism, how it compares to dual and single agonists, and laboratory handling.
The Science of NAD+
A researcher's guide to NAD+ (nicotinamide adenine dinucleotide) — the redox coenzyme at the center of cellular energy, sirtuin and PARP signaling, and aging research — plus how it compares to the precursors NMN and NR, and how to handle it in the laboratory.
Understanding BPC-157
A researcher's guide to BPC-157 (Body Protection Compound-157) — the gastric-juice-derived pentadecapeptide studied in tissue-repair, angiogenesis, and gastrointestinal models — covering its origin, mechanisms of interest, and laboratory handling.
The Copper Peptide GHK-Cu
A researcher's guide to GHK-Cu — the copper-binding tripeptide — covering its chemistry, its natural decline with age, the skin, collagen, hair, and antioxidant pathways it is studied against, and laboratory handling.
A Researcher's Guide to Tesamorelin
A researcher's guide to Tesamorelin — a stabilized analog of growth-hormone-releasing hormone (GHRH) — covering its structure, how researchers study its action on the GHRH receptor and the downstream growth-hormone and IGF-1 signaling, how it compares to other GHRH-family peptides, and laboratory handling.
Understanding TB-500
A researcher's guide to TB-500 — the research peptide associated with thymosin β4 (Tβ4) and its actin-binding region — covering the G-actin-sequestering mechanism and the cell-migration, angiogenesis, and tissue-repair models it is studied in, alongside laboratory handling.
A Researcher's Guide to Sermorelin
A researcher's guide to Sermorelin — the synthetic GHRH(1–29) fragment of growth-hormone-releasing hormone — covering its structure, how researchers study its action on the GHRH receptor and the downstream growth-hormone and IGF-1 axis, how it compares to tesamorelin and other GHRH analogs, its historical development as Geref, and laboratory handling.
