Bubbles
bubbles in urine is most likely proteinuria. Some protein in urine is normal-- most people will pee out around 100-200mg per day or protein, but more than that could be from medication use that is affecting the kidneys, stressed kidneys, diabetes, not drinking enough water....
With bodybuilders we can sometimes up the water intake and take digestive enzymes and/or bromelain (I like both together) to help with protein absorption. I haven't taken Tren in a loong time and never again would I use it. Tren, imho, is the best steroid for gains--period..it's also the best to hold onto gains when dieting. However, the sides suck--- irritabilty, sleeplessness, limp dick, dare I say "rage" (ok, not the way the public would think of it, but Tren can make a normally laid back guy pretty angry-- especially if you don't watch the blood pressure).
I think Tren does stress the kidneys, too many people with dark urine and bubbly pee when using Tren.....thats my 2 cents..
