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.

WHAT CUSTOMERS ARE ACTUALLY SAYING
Buying retatrutide in the UK
Most UK searches for retatrutide end on forums or on sites that only sell vials of lyophilised powder you have to reconstitute yourself. Synedica ships a filled pen: the dose is already prepared, so there is no mixing, no bacteriostatic water and no guesswork about concentration.
You will see the peptide written both as retatrutide and as reta — including in the product name LY3437943. They refer to the same triple GLP-1 / GIP / glucagon receptor agonist.
The pen is pre-filled at a known concentration and dosed in fixed increments. Each pack includes a printed usage protocol. The 40mg and 80mg packs also include the smoothie and shake book plus an AI dosing reminder.
Every order is dispatched with tracking, and support is available by email at support@synedica-reta.com before and after you buy.
