Yeah, here's a suggestion, try a different site.
No one's going to advocate or promote anyone doing anything illegal here. Tell your client to educate himself enough to make his own informed decision, you and him will stay out of hot water in the long run.
We're not promoting or advocating illegal activity, these forums are to inform people, and also for entertainment purposes
'Sides for all you know he's in Thailand where this is perfectly legal. This is the steroids section so its perfectly acceptable to talk about steroids!
Test, cypionate and sust are types of testosterone while the Deca and Tren are not. Is he trying to form a cycle out of all this stuff? Both you and him need to do massive amounts of research, you dont start stabbing needles into your body unless you know exactly what you are doing. Based on the information you have given it looks like he's trying to cook something up, slow him down, take this slow, there is no rush. Whatever you do, don't combine Deca and Tren, that's a recipe for disaster (gyno and limp ****).
What are his stats? You'll want to look into a 10-12 weeker with a test base, maybe a low dose of deca.
