Caught both sons doing steroids

I suspect the talking back has ZERO to do with what you found (post pics so we can see if they are actually steroids).
You said:
Talking back to me and being smart asses. One is 18 in the other is 17 years old
Teens do that.
they both have their own rooms in the basement and I pretty much let them do what they want.
There's an issue. Don't. They'll hate it now and thank you for it later
I've seen them smoke pot before but didn't really think much of it because I used to smoke it as well when I was in college.
See above
They also sneak girls downstairs and I'm okay with that as long as they put a hat on it.
See above AGAIN
Here's the brutal truth. They stay with you all summer and you're letting them do whatever the fuck they like. Probably partly as a f&&k you to their mother and partly cos you're being lazy when it comes to being a dad.
Heck even BM takes a belt to his kids

bros you need to watch your kids and not let them smoke weed, how is it that you cant see your son is high on weed? maybe you should have sat down and talked to him, show him brain disorder studies, explain the negatives and explain how he'll mess up his life starting to smoke weed at 17 and not just yell and scream but actually show the since and shit.

Thanks ur advice

Thanks for advice

Have a talk with them about using steroids at their age, send them here to read and ask questions. For now suggest healthier option that will help them work out:
CARDAZOL-NATURAL booster of cardio, stamina, energy, FAT loss
NUTROZOL-NATURAL booster of HGH, sleep/recovery aid
OSTAZOL-NATURAL booster of TEST and strength
