There is some good information here, as I have very limited knowledge of but in depth experience with IGF-1 Lr3 specifically. I began using it on a whim after procuring enough to experiment with a few years ago - I researched what I could find at the time and just went for it - keep in mind that is was after taking a very long break from any gear use of any kind aside from protein and standard vitamins. I have always weight trained depending on the degree my unfortunate health issues were at any given time.
Long story not so short for those interested - I ended up there after health issues caught up with me & I had to literally fight to survive. Once back on my feet & training for several months I started on Test E at 125mg/wk for 8 weeks. All going great.
I introduced IGF-1 Lr3 at 50mcg into the muscles I was training that day. So 50 each in bi's day 1, 50 in tri's day 2 and so on.
I did this for 6 weeks as I upped my Test to a modest 250 during this time.
For me, there was no denying the hard pumps into the sight injected muscle groups - the next day I could still feel it in delta as I moved to quads for the current day. I loved it & my output in the gym was very positive & fulfilling. Almost as good as my 25 year old angst filled self with unlimited life ambitions. My vascularity was out of this world. I don't spend a ton of time in the mirror but I was enchanted by the places veins were showing up on my body.
However by week 5 I began to have discomfort, like my spleen was rupturing (it happened before, same feeling). I went down to 30mcg per sight with no change. At the end of week 6 I stopped completely (just the IGF).
Without having time to see if the pain & discomfort would subside, I ended up in the ER two days after stopping with a perforated ulcer. It was a nightmare, blood from every single orifice. Major surgeries, in a coma, developed chronic foot-drop from my right knee down, blood clot, 2 blood transfusions & 52 days in the hospital.
I also came out forever a diabetic as it seemed my pancreas issues didn't appreciate that experience either. So ended up with a mass on my pancreas & intestines. Fairly recently that was removed along with part of those organs.
After all that blabbing my point is just to share my feelings on it. I'll never dabble in it again personally. From having to take insulin daily for the rest of my life (which I have to mention stays perfectly in range with my Lantus dose - for those who may see the sweet food I post at times in Nutrition), to having that mass form, it just appears that with the bit of research I've done that a fella in my position is just asking for more trouble here.
I've spoken to many who compete that utilize IGF, GH on top of who knows what else but of course their genetics, personal health along with the concrete commitment they execute perpetually is a whole level from what my humble goals have always been.
Regardless I'm loving learning more about it and everything else for that matter.
