Retatrutide 40 mg (PEN PEPTIDE) — detailed description

Retatrutide 40 mg by PEN PEPTIDE — triple agonist of GLP-1, GIP and glucagon receptors in a stabilized pen injector. Maximum volume in the PEN PEPTIDE lineup.

The 40 mg pen contains 200 units of 200 mcg each. Dosing table:

• 1 unit = 200 mcg

• 10 units = 2 mg

• 20 units = 4 mg

• 30 units = 6 mg

The maximum 40 mg volume allows completing a full course without frequent pen replacements. With a maintenance dose of 9 mg/week it lasts ~4.4 weeks, with 12 mg — ~3.3 weeks.

The formula is stabilized using MSSPT (Molecular Structure Stabilization Process Technology) — maintains structural integrity and bioactivity even during temporary temperature deviations above 8°C during transportation.

Purity ≥98%. Manufactured at GMP-certified laboratories in Europe.

Important: 40 mg is the total pen content of the active substance, not the weekly dose. In Phase 3 TRIUMPH, weekly doses ranged 2–12 mg (2 mg start, escalation every 4 weeks to target doses of 4/9/12 mg); the −28.3% result at 80 weeks (TRIUMPH-1, topline 2026) was achieved on the 12 mg/week dose.

Retatrutide (LY3437943) is an investigational molecule developed by Eli Lilly. This PEN PEPTIDE product is manufactured by a third party and is not manufactured, supplied or approved by Eli Lilly.

How it works — mechanism of action

Retatrutide is the only triple agonist of GLP-1 + GIP + glucagon. Acts on three receptors simultaneously:

1. GLP-1 — reduces appetite, slows gastric emptying, regulates glucose levels.

2. GIP — enhances GLP-1 effects and improves fat tissue metabolism.

3. Glucagon — activates lipolysis (fat breakdown) and thermogenesis (calorie burning).

In Phase 3 TRIUMPH-1 (topline 2026), participants on 12 mg lost an average of 28.3% body weight over 80 weeks (efficacy estimand) — the highest published result in the GLP-1 class. Phase 2 (NEJM 2023): up to 24% over 48 weeks.

Dosage

Standard starting dose: 2 mg once weekly subcutaneously.

Gradual escalation: 2 mg → 4 mg → 6 mg → 9 mg → 12 mg (Phase 3 TRIUMPH protocol, escalation every 4 weeks) depending on tolerability and response.

Subcutaneous injection in abdomen, thigh or upper arm area. Same day of the week.

Do not increase dose until hunger returns. Follow a balanced diet.

Who is Retatrutide 40 mg for

  • Retatrutide is an investigational drug (Phase 3), not yet approved by the FDA/EMA
  • Triple GLP-1 / GIP / glucagon agonist — a unique mechanism of action
  • For patients for whom single (Ozempic) or dual (Mounjaro) agonists did not deliver enough effect
  • Strictly under medical supervision

Retatrutide 40 mg — compared to other doses

  • Retatrutide 12 mg showed -28.3% weight loss over 80 weeks in Phase 3 TRIUMPH-1 (topline 2026, efficacy estimand); Phase 2 (NEJM 2023): ~24% over 48 weeks
  • In separate trials the numeric result is higher than Mounjaro 15 mg (-22.5%, SURMOUNT-1), but a direct head-to-head trial (NCT06662383) is still ongoing — clinical superiority has not been established
  • Key difference: retatrutide activates the glucagon receptor, increasing energy expenditure
  • Phase 3 results are topline/press-release level — full peer-reviewed publications pending; BLA (US) planned Q1 2027
