HGH Fragment 176-191 effects

  • Stimulates lipolysis (fat breakdown) in adipose tissue
  • Inhibits lipogenesis (new fat formation)
  • Does not bind the GH receptor
  • Does not raise IGF-1 or affect blood glucose
  • Targets stubborn / subcutaneous fat in cut-phase protocols

Survodutide effects

  • Substantial weight loss (~14-19% at highest doses in phase 2)
  • Suppresses appetite and slows gastric emptying via GLP-1
  • Increases energy expenditure via glucagon receptor activation
  • Reduces liver fat (notable MASH/NASH activity)
  • Improves glycemic control and fasting glucose
  • Lowers LDL cholesterol and triglycerides

HGH Fragment 176-191 side effects

  • Injection-site irritation or redness
  • Occasional headache
  • Mild fatigue at the start of a cycle (rare)
  • Transient flushing

Survodutide side effects

  • Nausea (most common, dose-dependent)
  • Vomiting
  • Diarrhea or constipation
  • Decreased appetite
  • Transient heart rate increase (5-10 bpm)
  • Injection site reactions
  • Mild fasting glucose elevation at low doses (resolves with titration)
  • Risk of gallbladder issues with rapid weight loss

HGH Fragment 176-191 dosing ranges

Fat loss / body recomposition

250-500 mcg · Once daily, morning, on an empty stomach (SubQ) · 8-12 weeks

Split-dose protocol for stubborn fat

250 mcg · Twice daily (morning + pre-cardio), fasted · 8-12 weeks

Survodutide dosing ranges

Obesity (phase 2/3 protocol)

MASH / NASH (phase 2)

1.2-6.0 mg · Once weekly SubQ (titrated) · 48 weeks minimum

Type 2 diabetes (phase 2)

0.3-4.8 mg · Once weekly SubQ · Long-term

HGH Fragment 176-191 vs Survodutide — common questions

What is the difference between HGH Fragment 176-191 and Survodutide?

HGH Fragment 176-191: The unmodified C-terminal fragment of growth hormone — the original lipolytic peptide. Typical dose 250-500 mcg. Survodutide: Dual GLP-1 / glucagon receptor agonist in late-stage obesity trials. Typical dose 300-6000 mcg. Both fall under the Weight Management category.

Can you stack HGH Fragment 176-191 and Survodutide?

Stacking HGH Fragment 176-191 with Survodutide is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.

Which is dosed more frequently, HGH Fragment 176-191 or Survodutide?

HGH Fragment 176-191 is typically dosed: Once daily, morning, on an empty stomach (SubQ) for Fat loss / body recomposition; Twice daily (morning + pre-cardio), fasted for Split-dose protocol for stubborn fat. Survodutide is typically dosed: Once weekly SubQ (titrated) for Obesity (phase 2/3 protocol); Once weekly SubQ (titrated) for MASH / NASH (phase 2); Once weekly SubQ for Type 2 diabetes (phase 2).

Are HGH Fragment 176-191 and Survodutide FDA approved?

HGH Fragment 176-191: Not FDA approved. Distinct from AOD-9604, which holds GRAS status as a food additive. Survodutide: Not FDA approved. Investigational compound in phase 3 clinical trials for obesity and MASH/NASH.
