The P.O is sending you off to a lab and not administering it there on site? You definitely need to sub either way.

It's kind of odd to me that they would send you somewhere to take it. But if that's the case, I can't say for sure but would imagine it would be more lenient, observation wise. But since it's not a standard pre-employment etc, I don't think anyone could say with complete certainty given where you are being sent from.

As for dilution. I can't say I'd recommend this route, ever. Based on my research and real life experiences, dilution will in fact hide the metabolites, but regardless you will come back as 'negative dilute.' This is not 'failing' but it's certainly not passing. Read all the threads you want on creatine loading etc, but again based on my research which is thorough, and multiple real life experiences, it's a wasted effort. Dilution should only be used as a stalling technique when you need to buy yourself some more time to go out and get synthetic. I can't say I'd ever recommend dilution from the get go, but this is just my $.02, take it for what it is. Research it.

But military wise, dilution works EVERY time as they preach hydration day in day out and do not do specimen validity checks. Obviously this doesn't apply to you, just good to know. I've passed 8 military tests through dilution, and came back 'negative dilute' on 2 civilian tests.

As for the whizzinator, I have one myself. The packet inside says it will maintain for 8 hours. I actually have mine strapped on right now practicing for my sub tomorrow. The heating duration is dependent on what brand of hand heaters you use. The one's included in the kit are garbage. I purchase mine separately at wal-mart, and apply with duct tape. I've never worn it for 8 hours straight, and honestly not sure I'd want to it's not all that comfortable, but I feel pretty confident it could stay within range for 8, to even 12 hours. Your body temp alone helps keep temperatures up on it, as the pouch is directly against your skin.

Whatever you decide to do, practice. And then practice some more. If you go whizzinator route, (which I recommend) wear it around your family and around town until it feels natural.

Hope I've helped :thumbsup:
