Prescribed IGF-1 LR3 vs. Research Grade

[Charger Hemi]

There is a huge price difference between a prescribed IGF-1 LR3 and research grade (which is available everywhere and cheap). I haven't tried either one but thinking about it.
The question is, has anyone tried it? What results do you except from it, and how long does it take before seeing results?

Thanks

Perception igf-1 is more concentrated then research grade its in mcg not mg people think thats igf-1 lr3 doesn't work because it doesn't bind the the igfbp's so it never reaches the the receptor but it does it does stimulate the type 1 IGF receptor and thus induce a higher level of activation of intracellular signaling, which is responsible for promoting cell proliferation. Results are great if you get a great product, really good pumps, increased muscle mass, muscle fullness and it also keeps you lean. 4 weeks on and 4 off with lr3 if prescribed then follow your doctors instructions because it's some short acting I wouldnt think you'd need time off... Hope this helped.
