Tesamorelin

Stabilized GHRH analog targeting visceral adiposity.

01 · Overview

What it actually is

Tesamorelin is sermorelin's stronger, longer-acting cousin — a stabilized GHRH analog with a trans-3-hexenoyl group added to prevent enzyme degradation. FDA-approved in 2010 as Egrifta for HIV-associated visceral adiposity, it's the only peptide in the GH-releasing family with a hard label indication for reducing visceral fat.

Off-label it's used by users targeting the same visceral fat compartment — the metabolically dangerous kind that wraps organs — and for the downstream benefits of a higher physiological IGF-1: better sleep, better body composition, and in some studies, improved cognition in older adults.

02 · Fit

Who this is for

Users specifically targeting visceral belly fat and lipid markers, often after a baseline blood panel confirms the issue.

03 · Mechanism

How it works

Tesamorelin is a stabilized GHRH analog approved clinically for reducing visceral adipose tissue by increasing endogenous GH and downstream IGF-1.

Documented effects

  • Significant visceral fat reduction
  • Improved lipid profile
  • Cognitive support in aging research
  • Sustained pulsatile GH elevation

04 · Use cases

Common uses

  • ·Visceral (deep abdominal) fat reduction
  • ·Improving triglyceride and lipid profiles
  • ·Body composition support in 40+ users
  • ·Cognitive support in older adults (investigational)

05 · Protocols

Cycle guidance clinicians commonly outline

Reference protocols paraphrased from published research and common clinical practice. Individual response varies. Work with a qualified provider before running anything below.

Standard visceral fat protocol

Protocol

1mg subcutaneous once daily in the evening

Duration

12–26 weeks — this is a slow-moving change

Notes

The clinical label uses 2mg daily. Many research users start at 1mg for tolerance.

Body composition / recomp

Protocol

1–1.4mg subcutaneous pre-bed

Duration

16 weeks on, 4 weeks off

Notes

Track waist circumference, not just scale weight — the change is visceral, not surface.

Baseline reconstitution

Reconstitute 10mg with 2ml BAC water for 5mg/ml.

06 · Combinations

Stacking notes

Common combinations: tesamorelin + AOD-9604 for visceral + surface adipose, tesamorelin + retatrutide for aggressive body composition change, tesamorelin + TB-500 for training recovery during the deficit.

07 · Safety

Side effects & contraindications

Commonly reported effects

  • ·Injection-site redness and itch (common)
  • ·Water retention in the first 2–3 weeks
  • ·Joint aches, especially wrists and fingers
  • ·Slight rise in fasting glucose (monitor if diabetic)
  • ·Head-flush shortly after injection

Talk to a doctor first

  • ·Active cancer or history of it
  • ·Diabetic retinopathy
  • ·Uncontrolled diabetes
  • ·Pregnancy and breastfeeding
  • ·Pituitary tumor or surgery history

08 · Trivia

Fun facts

  • 01FDA-approved in 2010 as Egrifta — the only GHRH analog with a hard label for visceral fat.
  • 02The single hexenoyl modification is what gives it a 15x longer half-life than sermorelin.
  • 03In one NIH study of older adults it improved cognitive performance on multiple measures.
  • 04Real-world visceral fat reduction in trials averaged around 15–18% at 26 weeks.

09 · FAQ

Common questions

Sermorelin or tesamorelin?+

Sermorelin is gentler and daily. Tesamorelin is stronger, longer-acting, and specifically evidence-backed for visceral fat. Pick tesamorelin if visceral fat is the target.

Do I need to check my IGF-1?+

Yes — a baseline and one at 8 weeks. Keeping IGF-1 in the upper physiological range is the goal, not exceeding it.

Why the evening dose?+

Matches your natural nighttime GH pulse. Also, morning glucose readings stay cleaner if you dose at night.
