Studies sampling before and after a bout find modest rises in total and free IGF-1 that track the exercise and resolve quickly. Growth hormone rises much more and the IGF-1 response is not proportional to it, because hepatic synthesis takes hours. Binding protein changes — a rise in IGFBP-3 fragments, a fall in IGFBP-1 with insulin — alter free IGF-1 more than total.
The rodent brain-uptake studies on the neuroscience page relate to this acute phase.
Resistance training increases IGF-1 messenger RNA and protein in the trained muscle within days, with the Ec splice form most responsive to load. Circulating IGF-1 after months of training is as likely to be unchanged or lower as higher, and energy balance confounds it: training with inadequate intake lowers IGF-1. Meta-analyses find no reliable effect of training on resting blood levels.
Muscle growth with training is attributed to local IGF-1 and other local factors, not to circulating hormone.
Because exercise is the most common natural modifier of the system and because the blood-versus-muscle distinction is the recurring theme of IGF-1 biology. It describes no use of the pack.
