What it is
Inside is retatrutide, a peptide built of 39 amino acids, the same building blocks that every protein in your body and your food is made from. In other words, it's a concentrated set of the individual parts of a protein.
How you use it
It comes as a pre-filled, ready-to-use pen. One click, once a week. One pen = up to 8 weekly doses = 2 months.
The result
Less hunger, steady fat loss. Up to 24% body weight.
P.S. Physical activity can slightly speed up the process and strengthen your final results.

Why the pen format matters
Most retatrutide sold online is a vial of freeze-dried powder. You then have to buy bacteriostatic water, work out the concentration, draw the right number of units and hope the reconstitution was accurate. Every one of those steps is a chance to under- or overdose.
A 40mg pen removes all of it. The peptide is already in solution at a known concentration, the pen doses in fixed increments, and the same pen covers the whole titration from the starting dose upwards. If you are comparing with a vial you already have, work out your dose with our peptide calculator.
