Compound profiles covering identity and chemistry, how lyophilised peptides are stored, reconstituted and tested in the laboratory, and how research peptides are regulated in Australia. Every article cites its sources.
A plain-English primer on research peptides: what a peptide is, how peptides are built one amino acid at a time on a resin bead, why they arrive as a freeze-dried powder, and what "research use only" does and does not mean.
A section-by-section guide to reading a peptide certificate of analysis: identity, HPLC purity, net peptide content, counter-ions, water, endotoxin, and the red flags that mean a COA does not check out.
How reverse-phase HPLC and mass spectrometry are used to test peptide purity and identity, how to read a chromatogram and a mass spectrum, and what each method cannot tell you.
A laboratory guide to storing lyophilised and reconstituted peptides: freezer temperatures, moisture, oxidation-prone residues, light, freeze–thaw cycles and adsorption to containers.
What bacteriostatic water actually contains, how it compares with sterile water, when benzyl alcohol can interfere, and how to reconstitute a lyophilised peptide and calculate stock concentrations.
A chemical profile of BPC-157: the 15-residue sequence and its identifiers, salt forms, how identity is checked in the laboratory, storage, and its place in the Australian Poisons Standard.
A chemical profile of retatrutide (LY3437943): what "triple agonist" means at the receptor level, its non-coded residues and fatty diacid, its identifiers, laboratory handling and regulatory status.
A chemical profile of TB-500, the N-acetylated LKKTETQ fragment of thymosin beta-4: identifiers, how the fragment and the full protein differ, where descriptions disagree, and how identity is checked.
A chemical profile of GHK-Cu, the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine: how the copper is bound, the 1:1 and 2:1 forms, the names in use, bench handling and regulation.
A chemical profile of MOTS-c, the 16-residue peptide encoded in the mitochondrial 12S rRNA gene: what a mitochondrial-derived peptide is, its identifiers, oxidation-prone residues and handling, and its status.
A chemical profile of Semax (Met-Glu-His-Phe-Pro-Gly-Pro): how the ACTH(4-7) fragment and the glyproline tail make up the molecule, why it has two names, its identifiers, oxidation-prone methionine and status.
A chemical profile of Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro): its tuftsin core and glyproline tail, where it was developed, its identifiers and salt forms, solvent choice and Australian status.
What the TGA, the June 2026 Poisons Standard, the Therapeutic Goods Act and customs law actually say about peptides, "research use only" labels, import controls and advertising in Australia.
