IGF-1 · measured in ng/mL
Growth signal — a longevity tightrope between cancer and frailty.
U-shaped (a sweet spot)Reference range
An assay-specific reference interval has not yet been added to this guide.
Use the interval printed beside this exact result, including its specimen, units, age/sex group and collection conditions. A range for a similarly named test may not apply.
Optimal range / clinical target
PeptideLab has not verified a separate ‘optimal’ target for this measurement. Reference intervals, diagnostic cutoffs and treatment targets answer different questions.

Does insurance cover IGF-1 testing?
When a clinician orders IGF-1 for a diagnosis or to follow a known condition, most plans cover it — and many cover routine screening as $0 preventive care for eligible adults. The catch is you need a qualifying reason and an in-network order; a “I just want to see my number” request often isn’t covered, and if you haven’t met your deductible you can end up paying the lab’s full list price anyway.
The direct-pay prices above skip insurance entirely: you pay the cash price, test on your own schedule with no doctor visit, and it’s HSA/FSA-eligible. For a single marker that’s often cheaper — and faster — than a copay plus deductible exposure.
IGF-1 inside a bundle
Every compared membership/panel that includes IGF-1, cheapest first. Worth it when you want several markers at once rather than a single test.

| Hundred | Annual membership | 160+ 74 biomarkers mapped | $199/yr |
| Life Extension (Elite) | One-time à-la-carte | 45+ 49 biomarkers mapped | ~$449 one-time |
| Marek Health | Annual membership | 80+ 55 biomarkers mapped | ~$495/yr |
| Lifeforce | Subscription + diagnostic | 51+ 49 biomarkers mapped | ~$2,137/yr |
What IGF-1 is
A liver-produced growth mediator of growth hormone, driving cellular growth and anabolism. It is the stable readout of GH activity and is strongly age-dependent, peaking in adolescence and declining with age.
Why it matters for longevity & performance
One of the most debated longevity markers and genuinely U-shaped: low IGF-1 signaling extends lifespan in models and reduces cancer risk, but too-low levels in humans associate with frailty, sarcopenia, and mortality.
IGF-1 & peptides — what to watch
If you’re running peptides, TRT or HRT, these are the compounds studied in relation to IGF-1 — useful for deciding what to track. Research associations for monitoring, not medical or dosing advice. Tap one for its full profile.
IGF-1 testing — frequently asked
Do I need to fast for a IGF-1 test?
No. IGF-1 does not require fasting — you can test any time of day.
Do I need a doctor's order to get a IGF-1 test?
No. Direct-to-consumer labs (GoodLabs, Ulta, Quest and Labcorp OnDemand) include the physician order in the price — you order online and visit a draw site, no appointment with your own doctor needed.
How fast are IGF-1 results?
Usually 1–3 business days after your blood draw; most results post to the lab's online portal.
What's the difference between the standard and optimal IGF-1 range?
Reference intervals describe results in a reference population; they do not by themselves diagnose or exclude disease. A treatment target depends on the condition and the person. PeptideLab has not verified a separate ‘optimal’ target for this measurement. Reference intervals, diagnostic cutoffs and treatment targets answer different questions.
Which peptides affect IGF-1?
Compounds studied in relation to IGF-1 include CJC-1295 (DAC), Ipamorelin, Sermorelin, Tesamorelin, MK-677 (Ibutamoren), HGH (Somatropin). These are research associations for monitoring — not medical or dosing advice.
Does insurance cover IGF-1 testing?
Often, when ordered for a diagnosis; many plans cover it as preventive care at no cost for eligible adults. The direct-pay prices above let you skip insurance and test on your own schedule.
