Educational summary. See Sources & research below for the underlying studies.
What it is
Tesamorelin is a GHRH analog studied specifically for deep belly (visceral) fat.
Best for: stubborn visceral fat around the organs
Edge: targets the fat that diet alone often misses
Bonus: supports sleep and recovery via growth hormone
How it works
It tells the pituitary to release your own growth hormone.
Raises natural GH in clean pulses
GH then mobilizes deep visceral fat
Acts like a stronger, targeted sermorelin
Dosing and mixing
Reference tiers only. Track the dose you are already taking.
Low
1 mg/night
FOR Gentle support or easing in
BENEFIT Often picked as the lower-exposure tier in GH and sleep discussions
Standard
2 mg/night
FOR Visceral fat reduction, the studied dose
BENEFIT The tier most often cited in visceral-fat research
High
2 mg/night, longer cycle
FOR Stubborn cases run over more months
BENEFIT People pick this when following longer-duration research discussions
Schedule: Inject nightly before bed. Effects build over months.
Beginner ramp: Most start at the studied 1 to 2 mg, little ramp needed.
Mixing (reconstitution)
BAC water is bacteriostatic water, the sterile water you mix in.
A 10 mg vial with 2 mL BAC water is a common starting point.

How to take it
Inject under the skin at night, on an empty stomach.
Before bed works with your natural GH cycle
Rotate the spot to avoid irritation
Refrigerate the mixed vial between doses
What to expect
Weeks 1 to 2
Often better sleep first, little visible change yet.
Weeks 3 to 6
Recovery and sleep improve, the waistline starts slowly.
Months 2 to 6
Main window for visceral-fat reduction.
Keep in mind
It targets deep belly fat, not surface weight, so be patient.
Side effects
Commonly reported
Injection-site reaction
Joint aches or stiffness
Mild water retention
See a clinician if
Swelling, or numbness and tingling that persists
Storage
Keep it cold, before and after mixing.
Powder: refrigerate
After mixing: fridge, use within about 4 weeks
Do not freeze, keep out of light
Common stacks
Tesamorelin + Ipamorelin: people combine these when researching two GH-related pathways
Tesamorelin + a GLP-1: people combine these when both GLP-1 and visceral-fat research are relevant
Sources & research
Reduced visceral fat in studies, including HIV-related belly fat.
Clinical trials · Falutz et al., NEJM 2007
Mechanism
Works by raising natural GH rather than injecting GH.
