Pre-filled research pens
Ready-assembled research pens holding a fixed, labelled quantity of peptide — tirzepatide 40 mg, retatrutide 40 mg and the GHK-Cu / BPC-157 / TB-500 Glow blend.
Why a pen format
A pre-filled pen takes reconstitution out of the bench workflow and keeps the quantity per unit consistent from batch to batch. Each pen is labelled with its compound and total fill and is supplied with batch documentation.
Pens are the most requested format in our catalogue, so they are held in stock in the UK and dispatched the same working day when ordered before 12:00.
Which pen
The Tirzepatide Pen holds 40 mg of the dual GIP / GLP-1 receptor agonist. The Reta Pen holds 40 mg of retatrutide, the triple GIP / GLP-1 / glucagon agonist. The Glow Pen holds a dermal-research blend of GHK-Cu, BPC-157 and TB-500.
If your protocol needs flexible concentrations instead, the same compounds are available as lyophilised vials in the GLP-1 and peptide-blend ranges.
