Background

PSA (prostate-specific antigen) is a single-chain protein containing 237 amino acids, belonging to the tissue-specific chymotrypsin-like serine protease family, which can break down the main mucin in semen and liquefy semen. PSA is tissue specific and only exists in the cytoplasm of human prostate acinar and ductal epithelial cells. PSA is not tumor-specific. Prostatitis, benign prostatic hyperplasia, and prostate cancer all lead to an increase in total PSA levels (free PSA plus combined PSA).The main function of PSA is to decompose the colloidal protein in semen, liquefy the colloidal semen and enhance sperm mobility. Small amounts of PSA can leak into the blood from the prostate. However, the increase of PSA in serum is seen in pathological states of the prostate, such as prostatitis, benign prostatic hyperplasia and prostate cancer. This product is the recombinant human PSA protein expressed from human 293 cells (HEK293).

Hotel Grand Set of 2 pillows
Size: King
Excellent quality and comfort. The pillows are soft but with the perfect support, ideal for any sleeping position. They feel fresh thanks to the cotton cover and keep their shape very well. Without a doubt, a great purchase for a hotel-like break at home.

Highly recommend
Size: King
These pillows are super comfortable and feel just like hotel quality. They’re soft but still give great support for my neck and head. I’ve been sleeping much better since I got them. They stay fluffy and don’t go flat, and the material feels nice and cool. Definitely a great purchase

Time will tell
Size: King
I won’t actually use these for a few days when my mattress arrives. Unboxed this morning and they are not as plump and full as I expected but they’re laying out to expand. Overall first impression is they felt comfortable and I could adjust them with my hands. They seem well made and durable. Cant say anything yet about firmness or shape retention since I’ve not used them. They feel like they will be soft. So time will tell but so far I’m loving what I see.

HOTEL pillows King Quality is Great
Size: King
Just got these pillows today. I have never spent dollars on pillows; but I wanted Hotel Grand like the ones that I sleep on in the Hotels and these fit the bill. Large King is what I got and so far so good. Firm and Squishy like I like. I was impressed with the quality -- now lets just give them a few days rest. I am sure they will be GRAND.
