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.
Regulation
The 2026 list names dozens of growth-hormone peptides as prohibited at all times for athletes. But the silences in Section S2 — BPC-157, TB-500,…
Regulation
A research peptide sold across Europe, never approved as a medicine, and quietly governed by the question almost nobody asks correctly.
Regulation
RUO is a labelling category about intended use, not a quality grade or a safety claim. It is legitimate for genuine laboratory science —…
Methods & QC
A lyophilised vial and a pre-portioned capsule are not two flavours of the same product. They are two answers to two different experimental questions…
Methods & QC
A methods comparison for laboratory sample preparation: how solubility, pH, preservatives and stock longevity dictate which diluent reconstitutes a lyophilised research peptide cleanly.
Guides
A field map for researchers: how synthetic, sequence-defined peptides are classified, made and characterised — and why the honest evidence runs from approved drugs…
Comparisons
Three peptides chase the same idea — stabilise growth-hormone-releasing hormone so it drives pulsatile GH at the pituitary. They are not three equal options.…
Comparisons
Two peptides from one scaffold took opposite paths — one to a regulatory approval, the other to the grey market. A precise, evidence-honest comparison…
Comparisons
They differ by one letter and a world of pharmacology. One is a comparatively selective alpha-MSH analogue licensed as an orphan medicine; the other…
Comparisons
Two molecules lumped together as metabolic small molecules that share no target, no mechanism and no research question, set side by side.
Comparisons
Two synthetic heptapeptides from the same Soviet-era programme, built on different parent molecules and studied along sharply divergent mechanistic lines.
Comparisons
Two compounds, one pathway, one enzymatic step apart. A precise, evidence-honest look at when researchers reach for the precursor versus the coenzyme.
Occasional, considered notes on the compounds and the literature. No noise.
