DSIP 5 mg ships from Southampton with Solent Peptides. Pre-mixed as standard. Guest checkout, or create an account to track the order. A nonapeptide originally isolated from cerebral venous blood, studied in sleep-regulation and neuromodulation models. Also listed as Delta sleep-inducing peptide. The listed aliquot is 5 mg. Each batch is HPLC-checked (CAS 62512-31-0). Lot number is on the vial. Want it in a research pen instead of the vial? That is a £5 add-on — still pre-mixed. Research supply, not a licensed medicine.
DSIP is released at ≥ 99% (HPLC). Each lot is HPLC-checked against the published identifiers — not a generic claim copied across the catalogue. Keep the lot number on the vial with your notes. Purity describes what is in the bottle. It is not a medical claim.
+£5 add-on. Same pre-mixed liquid, loaded into a research pen for measured handling. Research use only — not a licensed medical injection device. DSIP in the pen is the same pre-mixed liquid, just in a research pen for measuring small amounts. Not a licensed medical device. Posted in a plain carton. Next working day to most of the UK once payment has cleared.
