It is common to sweat when taking clen, Tren and deca, but it is worth, you can wear comfortable tshirt which sweat absorption and flash drying when training.
I sweat PROFUSELY too, and no matter how many layers I have on that day, they all always get drenched... take them off one after the other during the workout, and wait till I'm done to put on clean fresh clothes.
Only case I'd change while I'm training is if I start noticing my sweat is stinking for too much acidity... just a matter of respect for other gym members.
