But like most are saying this is really all on you. Read the sources threads or go to the testing section and you can easily see who tests their products and also the members contributing with their own test reports and bloodwork.
All sources are not equal. It’s up to you to read as much as you can and make a decision with the information that’s provided within the threads.
Take your time and read before ordering anything and don’t take anyone’s word that a source is ever good to go.
@HIGHRISK commented already you’re being a little impatient here. You have to give it time to work along with your nutrition and training.
If you ever have doubts on anything you’re running send it off for testing. The testing forum also has testers that provide this service. Once again you’ll have to read and decide which one is best for you to use.
