5-Amino

5-Amino is presented here as a laboratory catalogue entry for research environments that need clear identification, labelled variants, and direct access to supporting records. The current listing includes 1 labelled variant: 50mg. That structure keeps the page useful as both a procurement reference and an indexable resource covering stock visibility, pricing context, and documentation.

Within the wider Au Peptide Labs catalogue, 5-Amino sits alongside Retatrutide, Tesamorelin, and Ipamorelin. Researchers often review neighbouring compounds before selecting a comparator or deciding which sequence belongs in a screening panel. Keeping those internal paths close to the product page improves traceability and helps laboratory buyers compare materials without relying on vague or consumer-style copy.

In research literature, 5-Amino is generally treated as 5-amino-1-methylquinolinium (5-amino-1MQ), a small-molecule nicotinamide N-methyltransferase (NNMT) inhibitor used in one-carbon metabolism and epigenetic methylation research. 5-amino-1MQ competitively inhibits NNMT — an enzyme that converts nicotinamide (vitamin B3) to 1-methylnicotinamide using S-adenosylmethionine (SAM) as the methyl donor. By blocking this reaction, 5-amino-1MQ increases the cellular SAM:SAH (S-adenosylhomocysteine) ratio, which enhances the methyl-donor capacity of the one-carbon pool available to histone and DNA methyltransferases. This shifts the epigenetic landscape toward increased H3K4me3 and H3K27me3 marks in cell models, linking NNMT inhibition to chromatin remodelling research. NNMT is overexpressed in multiple adipose tissue depots and certain cancer types, making it a target of interest in both metabolic and oncology research contexts.

Unlike the peptides in this catalogue, 5-amino-1MQ is a quinolinium small molecule — its research applications centre on enzyme inhibition biochemistry, one-carbon cycle flux analysis, and epigenomic profiling rather than receptor pharmacology. Isotope tracing experiments (¹³C-methionine or ²H-SAM) are frequently used alongside NNMT inhibitors to map methyl group flux quantitatively. For laboratory teams, the practical emphasis is usually on sequence identity, receptor or pathway relevance where documented, and whether 5-Amino behaves consistently across stability, purity, and analytical verification workflows. Variant labels on this page support clearer internal referencing when multiple labelled variants are under review.

If a product-specific file is not attached to this listing, the wider COA library remains the correct reference point for current published documentation. The COA section is useful for confirming how the product is labelled in the catalogue, whether purity information has been published, and whether the laboratory record for the material is complete before bench use.

When teams compare 5-Amino with Retatrutide, Tesamorelin, and Ipamorelin, COA access also helps keep comparator decisions grounded in documented material identity rather than assumption. That is especially important for research pages that combine pricing, variant selection, and analytical records on a single URL.
