Why do growth-hormone peptides make me feel puffy?

Updated 2026-05-05

Growth-hormone-releasing peptides like CJC-1295, ipamorelin, sermorelin, and tesamorelin can hold water under your skin for the first 2-4 weeks. You may feel puffy in your hands, ankles, or face. Some people also get tingling fingers, sore wrists, or stiff joints. This is the body adjusting to a higher growth-hormone signal. It usually settles down once your dose stabilizes. If it is severe or lasts past week 4, drop the dose.

IfIf your hands or ankles feel puffy in the morning
Thenthen drink more water and cut sodium for a week - dehydration makes the swelling worse
IfIf your fingers tingle or wrists ache (carpal-tunnel feeling)
Thenthen drop the dose by a third and reassess after a week
IfIf puffiness gets worse each week instead of better
Thenthen stop the peptide and message your prescriber - this is the most common reason people quit GH peptides
IfIf you have heart failure or kidney disease
Thenthen do not start a GH-releasing peptide without a doctor - fluid retention can be dangerous
Key facts
  • GH-releasing peptides bump IGF-1, which causes the kidneys to hold sodium and water short-term
  • The Egrifta SV prescribing label lists fluid retention symptoms (edema, joint pain, carpal tunnel) as the most common side effects
  • Symptoms usually peak in weeks 2-3 and fade by week 6 if the dose is stable
  • Older users and women report carpal-tunnel-type tingling more often than younger men
  • Higher doses (over 2 mg/day tesamorelin equivalent) drive more puffiness
