I know 1st hand had frustrating it can be especially after you have spent the money and the temptation to still use it just for the off chance it's legit; it's not...

It's not even under dosed. They is no such thing as under dosed or weak HGH. It's a multi million dollar process, not something someone can manufacture at home or even in a small lab.
There are 1000s of back room labs in china producing copies of hgh. Several years ago it use to be possible to find a few manufactures but then the Olympics hit and that cut off 90% of the supply then all the fake labs started up making copies that were hard to tell the difference than the original labels and boxes so legit hgh all but dried up.
There has been ongoing discussion about this for several years now. The only people who are saying what they got is good are people who dont want to admit they wasted their money or people who are trying to sell something.
