IGF1-lr3 doesn't show itself in serum IGF1 test, this is a scientific simple fact, the molecule is changed and simply doesn't screened by the ELISA test.
For general knowleddge you may check out here a review on IGF1-lr3 and IGF1 -
http://www.professionalmuscle.com/f...din-igf1-lr3-vs-increlex-prescribed-igf1.html
What I speculate and would like to introduce here is that using IGF1-lr3 does increase circulating IGF1 levels
The member who brought it to my attention is the buck1973 actually. He has to comment here in order to realize where he brought this notion from.
So I tested this theory on an athlete who is close to me -
He's using GH at 4-6 iu a day year round, here is the basic protocol we used -
day 1 - IGF1 serum test morning regular procedue - 343
day 2 - IGF1 serum test 3 hours post 100mcg IGF1 injection - 379
6 days wash out period and repeat -
day 1 - IGF1 serum test morning regular procedue - 350
day 2 - IGF1 serum test 3 hours post 100mcg IGF1 injection - 386
More test in this matter to come, I think that buck1973 will cooperate and investigate this matter thoroughly soon.
It's clear that IGF1-lr3 potentitae the GH effect on target tissues to secrete endogenous IGF1, my hypothesis is that this phenomena stems from the optimizing effect of combined IGF1-lr3 with GH on so many metabolic functions.
As shown in the endocrinologist review here - Metabolic actions of growth hormone: direct and indirect. - PubMed - NCBI - GH may exert metabolic effects either directly or indirectly through increased production of IGF-I. GH administration increases circulating IGF-I levels via stimulation of hepatic synthesis and secretion of IGF-I; it may also enhance local IGF-I synthesis, which exerts paracrine or autocrine effects.
This means that the IGF1-lr3 may potentiate local secretion of growth factor in muscle tissue directly and indirectly through the GH paracrine effect
