You don't really want elevated igf-1 levels. GHRP-2 or 6 or ipam, with mod grf(1-29) will really only elevate igf if you are taking it very frequently. I had severe water retention develop at over 4 doses a day, I was trying to get it in every 3 hours so sometimes up to 6 times a day. Started to have crazy problems at that frequency. I only get mild water retention when I take it maybe once a day for fasting, and then post lifting. I had igf checked prior and was a bit low, never checked during like you are asking for, but my opinions on things also changed so I didn't bother. I'm not taking any peptides currently as I also didn't want the excess hunger or water retention, ok I lied, I'm taking mt-II.
You might have to search elsewhere to find someone who has put the investment into blood work etc while on a high frequency of peptides, with good peptides.
