Here probably i only post positives about igf1, as ray seeing it generally on reparative ,constructive side.(according to danny roddy,thanks to him)
it is interesting most nutrient deficiencies lower igf1 but not GH!

Effects of triiodothyronine on the insulin-like growth factor system in primary human osteoblastic cells in vitro. - PubMed - NCBI
We conclude that IGF-1R and IGFBP-5 are thyroid hormone target genes in human osteoblasts, whereas IGF-1 mRNA expression itself appears not to be regulated by T(3) in hOB. However, T(3) stimulates IGF-1R mRNA expression as well as IGF-1 binding and IGF-1 induced cell proliferation in osteoblasts, thus suggesting thyroid hormone may potentiate the effect of IGF-1 at the receptor level. This may contribute to the positive effects of thyroid hormone on bone formation, which, in addition, may be modulated by increased IGFBP-5 expression.

T4 replacement increases the serum levels of IGF-I and ALS in patients with primary as well as central hypothyroidism.
