Hmmm, a thread that will get me to write instead of lurk. I dont know what the OP original question was about other than all three items. Let me share some wisdom with your brother.

1. Clen - lots of information on here about clen. I am not a fan of it myself. Diet is more important.
2. Tren - lots of information on here about tren. https://forums.steroid.com/anabolic-...ly-thread.html If you don't have experience with running a number of cycles then I would suggest you stay away from tren and stick with test.
3. Diazepam - it is a benzodiazepine. It is a scheduled drug that can get you into a lot of trouble. This drug a long half-life and high risk of addiction and can cause seizures if your body gets used to them and you stop taking them. I happen to take Valium / Diazepam and have for years due to a TBI (seizure disorder) in conjunction with a few other drugs. I am under a doctor's care and I worry about this medication all the time and take less than I am RX. IDK your medical history but if you are not under a doctor's care then do not take this drug PEROID.
