As some one already pointed out here . It doesnt matter if they are blue, red, yellow , Blue or poop brown!. bottom line is you need to know where they are coming from!
In china you have Pharma factories making HGH ( 4 or 5 of them ). HGH from this factories are great . HGH from factories also come in diffrent color tops.
Our HGH comes from factory and some times they have been blue tops and some times brown tops.Same HGH but for some reason this factory likes to change the tops.
But lately we have been able to buy with redtops only.
Another good thing about HGH from factory is that they get controlled and tested cause same factory might be producing Jin or another Brand.
Then you have Labs... They are alot of them in china they also make hgh with diffrent color tops. 90% of lab HGH is how do i say this nicely , well pure shit . And sorry to say alot of HGH that people buy here comes from this labs .
