01

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.

02

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.

03

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.

Five checks before you order

  1. 1. Ask for the COA by batch number. A generic PDF that never changes is not a certificate - it should name the batch you are being sent.
  2. 2. Check the format. Powder vials shift the reconstitution risk onto you. A pre-filled pen arrives at a known concentration.
  3. 3. Check shipping. Tracked delivery to a UK address, with a tracking number emailed to you, not an untracked envelope.
  4. 4. Check who you are buying from. A named company, a working support email and legal pages you can actually read.
  5. 5. Check the refund terms up front. They should be visible before payment, not buried after it.

Why a pen beats a vial

  • No reconstitution. The peptide is already in solution at the correct concentration.
  • Fixed dosing. The pen increments are marked, so you do not calculate units or draw from a vial.
  • Less waste. A single pen covers the whole titration schedule; leftover bacteriostatic water and partial vials are not needed.
