Plain-spoken notes on the compounds we supply — what the literature shows, how to read a COA, and the protocols that protect your data. Cited, never hyped.
Methods & QC
How a BPC-157 COA actually verifies the molecule: HPLC area-% purity, mass-spectrometry identity against the 15-amino-acid sequence, and the SPPS impurities to look for.
Comparisons
KPV and larazotide are both studied in intestinal-barrier and inflammation research, but by different mechanisms. A sober, RUO comparison — including larazotide's negative phase…
Comparisons
Methylene Blue and J-147 are both studied as mitochondria-targeting nootropic compounds, but their chemistry and mechanisms diverge sharply. A research-use comparison of an old…
Hormonal
A research-use guide to ipamorelin: how it engages the ghrelin receptor (GHS-R1a), why it is described as the first selective GH secretagogue, and an…
Tissue repair
A research guide to KPV, the C-terminal tripeptide of α-MSH: how PepT1 uptake, NF-κB/MAPK signalling and antimicrobial activity have been studied in gut and…
Skin & matrix
A deep research guide to GHK-Cu, the copper-binding tripeptide Gly-His-Lys. Coordination chemistry, extracellular-matrix and gene-expression mechanisms, and an honest in-vitro to limited-human evidence map.…
Comparisons
The name 'TB-500' covers two unrelated research molecules: full-length thymosin β4 (43 aa) and short Tβ4-derived fragments. What each one actually is, what the…
Comparisons
CJC-1295 DAC and CJC-1295 no-DAC (Modified GRF 1-29) share one peptide backbone but differ in half-life. A research-use-only comparison of structure, pharmacokinetics and the…
Comparisons
BPC-157 arginate vs standard BPC-157, compared for research: the salt-form (arginine vs acetate) chemistry, what it changes for solubility and handling stability, and what…
Guides
A provider-neutral, evidence-first checklist for evaluating any European research-peptide supplier — by the documentation you can verify, not the marketing you have to trust.
In the news
Blueprint's founder has run dozens of peptides through his body and his biomarkers. Ranked by evidence, his protocol separates the plausible from the speculative…
In the news
The GLP-1 shortage spawned a compounding boom. As the FDA winds it down, semaglutide is left as three distinct things that share a molecule's…
Occasional, considered notes on the compounds and the literature. No noise.
