Scientific Overview:

PE-22-28 is a synthetic peptide derived from the propeptide of Saposin C, comprising the amino acid sequence GVSWGLR. It acts as a selective modulator of the prosaposin receptor, GPR37, and is extensively studied in neuroscience and neurobiology research, particularly relating to its role in neuronal survival, neuroprotection, neuroregeneration, and modulation of depressive behaviours in experimental settings.

Due to its ability to influence cellular signalling and neurological pathways, PE-22-28 is of significant interest in studies focused on neurodegeneration, neuronal cell viability, and G protein-coupled receptor (GPCR) signalling mechanisms.

Great for busy feet

My five-year-old daughter loves these Skechers slip-ins—and she is not easy on her shoes! You can see in the photo, she’s already put plenty of miles on them. They’ve been through the washing machine at least twice and still look great—the bright colors are a big hit with her and they hold up well in the wash. One of the elastic bands on top did come loose, but I was able to fix it quickly with a dab of superglue. She slips them on and off all by herself, which is perfect as we’re still learning to tie laces. All in all, a great purchase for the price—especially since kids grow so fast and put their shoes through a lot!
