Research Notes
Laboratory reference articles on peptide handling, purity verification, storage and what the published literature reports. Written for researchers, not consumers.
Semax vs Selank: What the Research Literature Reports
Two heptapeptides from the same research lineage but different parent molecules — ACTH(4-10) and tuftsin — with different reported mechanisms.
