Ive tried sub q in the am and pm, pre workout, post workout, and before bed. The best results i got was from pre workout bi lateral injections, i did this using the FST-7 training method and i was quite happy with the results.
Scientifically speaking, training a muscle upregulates the IGF receptors correct? Yes! So since IGF-LR3 is long acting and systemic, if used prior to training ( 15minutes roughly ) then more of the IGF will be utilized due to the receptor upregulating. Plus when training a bodypart more blood is pumped into that area, so even if the IGF hits the blood stream it will eventually be returned to the desired area to be used.
