I don't have detection times in front of me, but
Tren is one of the longest (5 months I believe.)
Most employers only do a 5 panel drug
test, (herion, coke, that knida shit.) However, they can easily do a 10 panel if their is suspicion (you simply label it different when you send it to a lab), like if some little dorky boss of yours is jealous people say, "wow you're in great shape, etc."
Now thats very rare, but thats almost uniformly how its handled by Army, Police, even Corporate america. Let me repeat, its rare but if you have a yearly drug
test that you know about they probably aren't very interested in catching anyone, and more important the protocols used are most likely in a company handbook, or on the co. website , etc. look it up Bro.
Good luck.
