Studies that did not test the peptide alone1

In this study, IGF-1 DES (des(1-3)IGF-I) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking IGF-1 DES (des(1-3)IGF-I).

    In fibroblast collagen gels, the combination of des(1‑3)IGF-I and IGFBP-1 did not promote gel contraction.
