no hard science on tren or igf out there really but i've read in the BTPB book that tren upregulates your tren receptors, so seems like doing that and then flooding your body with IGF will do some good stuff, we'll see though, i'll be running tren ace and igf/ghrp for 6 weeks coming up here soon.
also i usually run 20mcg split between 2 or 4 muscle groups and i get noticable effects from that. 40mcg give me more effects but definately not 200% more that i can tell anyway, so i'll just stick to 20mcg E3D to be safe, its also much cheaper that way and you can pretty much run it forever
how long have you been on the tren alone?
let us know how it goes and if you see any sort of increase in teh gains over and above the tren alone!
PS: post cycle therapy without Tor is something i will never do. Tor is my new bff, that shiat brings me back like 10x faster than nolva/clomid. i would also make sure you leave at least a few weeks of not being on the igf before post cycle therapy so you can use teh igf during your post cycle therapy, tren seems to cause some serious shut down
