Now is summer here in Portugal and humidity here is always around 90%, we sweat alot even doing nothing or just eating. I finish my workout completely sweat and is very hard to train in that conditions ( hard to breath )
I train 5 on 2 off , 1 hour day , sleep 10 hours day including nap, eating 800ge carbs , 500gr protein around 7000 calories.

What do you think can be the causes of not gaining weight and losing pump and strengh in workout?
Dehydration?
Lack of minerals ( potassium , magnesium , sodium?
Use of masteron ( can cause dehydration) ?

Using test , deca, tren, masteron, drol, dbol, hgh , slin

Any help i will appreciate
