Labs don't mean anything, it won't show potency only whether or not GH is inside - they can put the minimum amount (ie 0.2IU) to make it pass and the rest is god knows what like Marcus said.
Put your health first and toss it in the garbage. Unless a vial/pen/cartridge says Pfizer, Eli Lilly, Novo, Hoffman, etc on it you are wasting your money and putting yourself at risk for no reason.
