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.

Fits smoothly
Size: Queen
I really like it. It fits smoothly with no wrinkles and no "crackling" noise. I have an older mattress that is not as deep as the newer mattresses and I have a hard time with new sheets being too loose and wrinkly. This mattress protector has all around elastic that should make it fit any size.

Very comfirtable
Size: Twin XL
With all the great reviews, I chose this brand mattress cover and am so glad I did. The cover went on easily, fits snugly and Stays on the mattress. Even tho the cover is not thick, it certainly makes a softer yet firm foundation to sleep on. There was no odor and no change in temperature. I think it is well worth the price.

Protects your mattress from toddler spills!
Size: Full, Size: Full
Writing this after my toddler spilled a ton of water on my bed (a new mattress). I didn't realize what she had done for about 1 minute. By the time I got her off the bed, pulled the sheet off and pulled the mattress protector off, the mattress was still dry! I felt the bottom plastic part of the mattress protector and could feel the coolness of the water, but not dampness. This thing works! Note, I don't know how it would perform if I had left it for a really long time. The protector is also very soft on top, not noisy, and easy to stretch over the mattress. You can kind of see the square shapes of the protector through the sheet, but I personally don't care. It was a great buy.
