It's really not hard to avoid getting ripped bro. You just have to do some research before you order.
Ask the source for pics of the HGH you are getting. Also confirm that it is in puck form and not loose powder in the vial. Some really crappy HGH is floating around that comes as a loose powder. Vacuum seal is also a sign of quality! while it doesn't really matter that much when you look at the whole picture it shows that wherever your HGH is being made that they at least have some high dollar machinery to put the final touches on their product.
Talk with your friends on here that use HGH, there are many guys on here that have been using HGH for years. Pick their brains and don't be shy to ask questions.
