DSIP crosses the blood-brain barrier freely an unusual property for a peptide of its size via a non-competitive, non-saturable passive mechanism whose physicochemical determinants (lipophilicity, charge, molecular weight, and protein-binding) are now well characterised
Creatine supplementation takes this a step further, as it has been shown that older adults who supplement with creatine and resistance train have better strength and muscle gain results than those who resistance train but do not take creatine
Similarly, SOCS4-CUL5 complexes ubiquitinate tau in human neurons, modulating its stability and correlating with susceptibility to tauopathies in both mice and humans (49)
Theyre also great for helping even skin tone, repair sun damage, or reduce the appearance of wrinkles
Effects on biological aging markers and cellular health emerge over months and may continue improving during off-cycle periods as activated cellular processes continue operating
