Tirzepatide — Mounjaro

More fat lost than on semaglutide — without eating less.

This is the finding nobody advertises, and it's the most interesting one in the whole category. In a head-to-head comparison using DXA, tirzepatide cut more fat mass than semaglutide and placebo. Yet both suppressed appetite equally — the drop in calorie intake did not differ between them 1.

So the extra loss isn't explained by eating less. The authors say it themselves: what the molecule does to energy expenditure and substrate use needs to be investigated 1. Something is happening beyond the stomach.

Now the question you actually have: will I lose muscle? Incretin drugs cost lean mass — about 10%, or 6 kg, “comparable to a decade or more of aging”. This applies to the whole category, not just here 2.

The countermeasure is written in the same review: resistance training over 10 weeks → about 3 kg of lean mass and +25% strength. The authors explicitly recommend it alongside treatment, and note that preserving lean mass may slow weight regain afterwards 2.

And so you know where it stands: in the only head-to-head obesity trial — 751 people, 72 weeks — −20.2% vs −13.7% for semaglutide, and waist circumference −18.4 cm vs −13.0 3.

And three numbers the scale doesn't show. Blood sugar: head-to-head against semaglutide, 1,879 people, HbA1c −2.30% vs −1.86% 6. Heart: 731 people with heart failure and obesity — cardiovascular death or worsening 9.9% vs 15.3% 4. Kidneys: versus insulin, the annual eGFR decline was −1.4 instead of −3.6, and kidney events were 42% fewer 5.

Four formats. Choose by what suits you, not by what sounds better.

Syringes: four single-dose, pre-filled at your dose — no measuring, no drawing up, no chance of getting lost in the zeros. One month. Pen: the same four doses in one device, with the extra charge.

Watch the pen number. “1 × 20 mg” isn't 20 mg in one go — it's 4 × 5 mg, a month in one pen. Always four times the dose, because it carries all four weeks.

Vial: plain powder, the cheapest per mg. You do the work — reconstitution, calculation, your own syringes. Reconstituted vial: the same, dissolved in 2 mL bacteriostatic water with 4 syringes included, +10 €.

The trade-off: the solution has a clock, the powder doesn't. Once reconstituted it needs the fridge and won't wait months. If you're starting now, it's convenient; if you're stocking up, get the powder.

Four formats, and the difference is how much of the work you do. Syringes: none. Pen: none, and everything in one device. Reconstituted vial: arrives ready, with syringes. Lyophilized powder: you prepare it, and it's the most stable over time. Choose by what you'll actually do — not by what sounds more serious.

Imagine the body you've always wanted, built on real science. Tirzepatide is one of the most talked-about peptides of its generation — and it deserves it.

Its secret is a beautiful double move: it talks to two receptors at once, GLP-1 and GIP. One gently curbs appetite, the other activates fat tissue and the feeling of fullness.

And the result isn't an empty promise: in the SURMOUNT-1 study, with 2,539 people, weight loss reached −20.9% in 72 weeks 1. One kilo in every five — like rewriting the rules of your body.

And the most beautiful part is that the story continues: in SURMOUNT-4, those who stayed on treatment lost another 5.5% 2. It's not a momentary glow — it's a journey that lasts as long as you keep it going.

Honesty has its place in a beautiful story too: experience varies from person to person, and nothing here is a magic wand.

We do it right from the very first moment: strictly for research use, with aseptic handling and a proper cold chain for every vial — because the beauty of a result always starts with the quality behind it.
