Analyzer is good to see what the purity an potency of the product you have an to see if your var isn't dbol ect.. Anabolic Lab on the other hand will not only test the potency along with purity but will infact test for microbiological contamination as well which is what you really wana be sure of with these pop up fly by night type of labs @OldmanRob .....I would trust testing from that site
