I can answer with clinical data.
Nutra IGF-1 is pure IGF-1, derived naturally instead of made synthetically (like synthetic HGH).
Firstly, it is certainly far safer than HGH therapy with no documented side over the last several years of testing (and no needles).
Secondly, Nutra IGF-1 will not make your body "dependent" on the outside hormone therapy like HGH shots.
Finally, Nutra IGF-1 has been shown to safely add IGF-1 to your body, gently raising to healthy levels over a period of days.
Whereas, HGH will deliver a much higher dose of growth hormones at the time of injection.
However, keep in mind, only a small portion converts into IGF-1 and makes it to your "free stores" the rest of the overdosage is what causes the "hormonal" side effects.
In the end, the same goal is achieved, maximized levels of IGF-1 - Nutra IGF-1 just does it in a safer (and less expensive) method.
Remember, GDR Labs has also privately tested Nutra IGF-1 on over 35,000 users with exceptional results (Over 90% reported physical benefit).
In my eyes, the results speak for themselves.
