I run my IGF1 after my cycle. Using it as a bridge inbetween. I have noticed increased bloodflow to the muscle worked, increased hunger,better sleep, and some increased strength as well. Keep in mind I am using with my HRT dose of 250mg/wk of Omnadren. I use it in a 4wk on/ 2wk off/ 4wk on method. I am sure I will see some increase in gains on next cycle.
