Only way to really know is to take some. I recently changed supplier and tried another make.
My HGH is always vacummed from what I have used. I vary my iu's, just depends how much I have and of I am taking with AAS.
I used to take between 2-6 iu per day.
Inject am and pm or post workout. Though for 3 months have have taken
8-10 iu three times per week post training.
The main thing if you get sore joints and ache, and you sleep like a baby and feel good in yourself I would say its legit stuff.
Pin away and she what happens if the only way to know with a new source.
Hope this Helps
