Tesamorelin Results
Tesamorelin results are measured on the GH/IGF-1 axis and body composition - specifically visceral fat. IGF-1 is the marker that confirms the compound is doing what it should.
Why measurement beats a before/after photo
Tesamorelin was developed to reduce visceral fat, and IGF-1 is the read on whether the GH axis is responding. A mirror cannot show you visceral fat or IGF-1 - both require measurement, and both are the actual "result" tesamorelin is known for.
What to track on Tesamorelin
A rise into (not above) the optimal range confirms the GH-axis response.
Waist reduction is the hallmark tesamorelin result; DEXA visceral fat is the precise read.
Watch it does not drift up - the GH axis can nudge glucose.
Lean-mass support + visceral-fat reduction is the intended composition shift.
Tesamorelin timeline: what tends to shift, when
IGF-1 climbs toward its new set point; this is the window to confirm the dose with a draw.
Body-composition changes (waist, visceral fat) become measurable.
The visceral-fat result accrues; glucose monitoring confirms the metabolic cost stays low.
Signal vs placebo: how to tell a real result
IGF-1 is the cleanest tesamorelin signal - a baseline-vs-6-week draw tells you immediately whether your dose is producing a GH-axis response. For the visceral-fat result, waist circumference is a reasonable proxy but DEXA is the precise read. Subjective "I look leaner" is the least reliable signal; the IGF-1 + waist pair is the real one.
How to actually track Tesamorelin results
Pull IGF-1 at baseline and ~6 weeks to confirm the response landed in range. Track waist circumference every few weeks and add a DEXA if you want the precise visceral-fat number. Watch fasting glucose alongside. That cluster is the tesamorelin before/after - and the IGF-1 number in particular is the thing your provider will want to see.

Frequently asked questions
How do I know if Tesamorelin is working?
Tesamorelin was developed to reduce visceral fat, and IGF-1 is the read on whether the GH axis is responding. A mirror cannot show you visceral fat or IGF-1 - both require measurement, and both are the actual "result" tesamorelin is known for. Track: IGF-1, Visceral fat / waist circumference, Fasting Glucose, Body composition (DEXA).
How long does Tesamorelin take to show results?
Weeks 1-6: IGF-1 climbs toward its new set point; this is the window to confirm the dose with a draw. Weeks 6-12: Body-composition changes (waist, visceral fat) become measurable. Months 3-6: The visceral-fat result accrues; glucose monitoring confirms the metabolic cost stays low.
How do I tell a real Tesamorelin result from placebo?
IGF-1 is the cleanest tesamorelin signal - a baseline-vs-6-week draw tells you immediately whether your dose is producing a GH-axis response. For the visceral-fat result, waist circumference is a reasonable proxy but DEXA is the precise read. Subjective "I look leaner" is the least reliable signal; the IGF-1 + waist pair is the real one.
