Preseed is good- heard that egg white might not be that ideal cos of the bacteria that might be in raw eggs these days- I guess if you were planning to use egg whiteS then organic ones might be better?
I got my preseed in UK, as I know you can't buy it in HK- what I would do is to try some of the websites to see if they would deliver to HK.
I use two websites to send Pre-seed to HK. One is Lullaby Conceptions and the other is Early -Pregnancy- Tests. Just Google both and you'll find them. Amazon wouldn't allow Pre-seed to be sent to me to HK. However I can personally vouch for the other two websites. They are fantastic. The service is fast and the stock a huge range of everything to do with fertility. Good luck!
I have a question hope its not too silly....pre-seed is a lubricant that helps with vaginal dryness only right? or does it actually boost your chance of conception? Or would it help no matter what as it acts as healthy cervical mucus and builds a better environment for the sperm to live?
