I have ordered from them twice. First time I bought 1 kit of Jintropin to check if the source is not a scam. I advice you to do so too because I was scammed 3 times before buying here. So, I got my order in 9 days after payment. Guys provided me tracking number and I could track it all the way to the USA. As soon as I got my first parcel I verified Jintropin on gen-sci and it was genuine.
My second order was of 5 kits and I got it too, but there were some problems with payment which were resolved. All 5 kits are genuine and I have already used 2 of them and it works perfectly.
Recommend this source. Real HGH for decent price.
