Research Guides
Research peptide guides
Clear, science-led explanations written for researchers. Every guide is framed for in-vitro laboratory research use only.
What are research peptides?
What peptides are, how they differ from proteins, why they are studied in the laboratory, and how to read a Certificate of Analysis.
7 min readWhat is BPC-157?
The pentadecapeptide BPC-157 — its structure, the signalling pathways it is studied in, and how it appears across research compound sets.
6 min readWhat is CJC-1295?
CJC-1295 — a synthetic GHRH (1-29) analogue studied for growth-hormone-axis receptor signalling, and how it is often paired with ipamorelin in research.
6 min readWhat is Tesamorelin?
Tesamorelin — a stabilised GHRH (1-44) analogue studied for hypothalamic–pituitary signalling and growth-hormone regulation.
5 min readWhat is Ipamorelin?
Ipamorelin — a selective pentapeptide growth-hormone secretagogue (GHSR-1a agonist), often studied alongside GHRH analogues.
5 min readWhat is TB-500?
TB-500 — a synthetic thymosin beta-4 fragment studied for actin binding, cell migration and cytoskeletal organisation.
5 min readWhat is GHK-Cu?
GHK-Cu — the copper-peptide complex (glycyl-L-histidyl-L-lysine + Cu²⁺) studied for copper-dependent signalling and matrix-related processes.
5 min readWhat is MOTS-c?
MOTS-c — a mitochondrial-derived peptide studied for energy sensing, AMPK signalling and mitochondrial–nuclear communication.
5 min readWhat is KPV?
KPV — the lysine-proline-valine tripeptide (α-MSH 11-13) studied for melanocortin-linked and inflammatory signalling pathways.
4 min readWhat is NAD+ (and is it a peptide)?
NAD+ is a central redox coenzyme — not a peptide. What it is, the enzymes and pathways it is studied in, and how it is supplied.
5 min readWhat is the Glow Stack?
A research compound set combining BPC-157, TB-500 and GHK-Cu (70mg total) — what each component is studied for and why they are presented together.
6 min readWhat is the Wolverine Stack?
A dual-peptide research compound set combining BPC-157 and TB-500 (20mg total) — what each component is studied for and why they are presented together.
5 min readWhat is the Klow Stack?
A four-peptide research compound set combining GHK-Cu, KPV, BPC-157 and TB-500 (80mg total) for multi-pathway laboratory study.
5 min readCJC-1295 and Ipamorelin: how the combination is studied
Why a GHRH analogue (CJC-1295) and a growth-hormone secretagogue (ipamorelin) are frequently studied together in growth-hormone-axis research.
5 min readHow should research peptides be stored?
Lyophilised vs in-solution stability, the cold chain, and the handling conditions that keep research peptides intact.
4 min readWhat is a Certificate of Analysis (COA)?
What a COA is, what HPLC and mass spectrometry confirm, and how to read one when evaluating a research peptide supplier.
4 min readBuying research peptides in the UK: what to check
A practical checklist for choosing a UK research-peptide supplier: COAs, HPLC purity, cold-chain dispatch and transparency.
