Well I've been using gear for about 20 hours now. No one suspects a thing. My obvious strength and mass improvements must be going un-noticed.
I don't plan on telling anyone except my wife, who already knows. She's my best friend so no problems.
The biggest concern that we have is not letting the kids know. Hate to have our son, who just went through DARE class find a stray pin laying around. We keep everything under lock and key and I don't plan on every playing with the stuff while they are anywhere close.
