Hi well i was in a friends house... and he found a bottle of twinlab andro fuel... he told me that was like 6 years old.. the bottle is opened but there are a lot of pills still there.. but the bottle was closed all that time and stored in a closet at normal temp and humd... also i didnt found any expiration date.. so i want to know is this product which is no longer in the market can be used after all that time.. or if it expires or something like that.. they seems to be in great shape... but i dunno... thanks a lot
