What it is

It's the new gold standard in metabolic peptides.

Retatrutide is a next-generation weight-loss peptide. It works on three appetite and energy signals at once — the same systems behind Ozempic and Mounjaro, but tuned harder.

In published clinical trials, people lost up to ~24% of body weight at 48 weeks at the highest dose. That's the strongest result on record for a peptide of this kind.

Benefits

What it does, in plain language.

Significant weight loss

Strongest fat-loss numbers of any peptide in this class.

Quieter appetite

Less head-noise about food. Easier to stop at 'enough'.

Better blood sugar

Steadier glucose, fewer crashes.

Lower triglycerides + LDL

Improves the markers your doctor checks at a yearly physical.

Less fat on the liver

Studied for fatty-liver reduction.

One injection a week

Set-and-forget. Same day, same time, every week.

How to use

Simple, step by step.

01

Start low

Begin at 1 mg once a week. Most side effects show up if you start higher.

02

Climb slowly

Increase by 0.5 mg every 4 weeks if you're tolerating it well, up to 3 mg max for general use.

03

Same day each week

Pick a day. The level in your body is steady at this cadence — no need to chase a window.

04

Inject under the skin

Belly (not within 5 cm of the belly button), thigh, or back of the upper arm. Rotate sites.

Typical doseTypical research dose: 1–3 mg once weekly.

Storage and handling. After mixing with bacteriostatic water, store in the fridge (2–8 °C). Use within 28 days. Unopened powder vials live in the freezer.
