This is plain-language harm-reduction information, not medical advice. Peptides discussed here are research compounds; most are not approved for human use. People will use them either way — we would rather they have the facts.

What it is

Survodutide is another GLP-1 + glucagon dual agonist, developed by Boehringer Ingelheim in partnership with Zealand Pharma. Phase II data shows ~19% weight loss at 46 weeks and impressive reduction in liver fat (MASH/NAFLD).

Still in trials as of 2026.

History

Developed by Boehringer Ingelheim / Zealand Pharma. Phase II results 2023; Phase III ongoing.

How it works

GLP-1 + glucagon dual agonism. Glucagon component appears to drive notable liver fat reduction in addition to weight effects.

Dosage

  • Starting: 0.3 mg once weekly.
  • Titration to 4–6 mg weekly over 12–16 weeks.

How it is taken

  • Subcutaneous injection.

How to reconstitute

  • 10 mg vial with 2 ml BAC water = 5 mg/ml. 3 mg = 60 units.

How it should arrive

White powder, sealed vial.

How it should look once reconstituted

Clear colourless solution.

What to expect, and when

  • Appetite suppression: within days.
  • Weight loss: ~19% at 46 weeks at top dose.
  • Liver fat reduction: 12–24 weeks for measurable change.

Side effects

  • Standard GLP-1 GI side effects.
  • Mild heart rate increase.

Risks

  • Pancreatitis.
  • Limited long-term safety data.

Potential gains

  • Strong weight loss.
  • Best-in-class liver fat reduction among the dual agonists.
