When you are doing a source check, what is an appropriate number of Mods that should give you the "ok" before you order from a place? I mean how many Mods need to give me the a thumbs up before I can go and trust a place to buys steroid from?
I am a little confused by your question. If any moderator approves a source, that source should be good to go. The moderators on EVO go through extensive work to make sure each source that is approved is providing quality products to customers, in a safe manner.
Usually, you don't need the approval of a moderator to purchase your gear from a particular supplier. You can just check out the customer feedbacks, and decide for yourself, if the supplier deserves your trust, or not.
