Using it
I have and do take it. I use 0.9 Mg/Kg, which is less than the studies. I do this for two reasons, it is early in the approval process, and it is very expensive. I read a scientific article online, but can’t find it for anything now, where a researcher was speculating the changes is the blood are similar to a particular kidney problem so it is possible there could be a health risk side effect. Sorry I can’t find the article and I’m not a scientist to be able to articulate it from memory. I have been keeping up with Phase II results and now the Phase III trials in China.
I just add it to capsules I make up with other things such as cardarine, beta alanine, etc.. I found at this low dose it does increase endurance and the effect last for about 1 ½ weeks after it is stopped. It also takes a few days on, before I notice any improvement. I also believe I need more sleep when on, because it works by tricking the body into thinking it is hypoxia (low on oxygen) so your body is working more than normal while asleep. I think you sleep similar to an altitude/hypoxia tent. For athletic events, I seem to do a little better with not taking it the day before. My schedule is 6 to 8 weeks on and 3 to 4 off.
If I had too chose between FG-4592 and ITPP, I would take ITPP. But together they are pretty good, because FG-4592 increases the oxygen caring ability of the blood and ITPP increase the oxygen releasing (off loading).
