You can buy protein urine testing strips at most pharmacies. It is a simple strip that you dip into your urine to check for many things like PH, ketosis and protein. Here is whats going on with your kidneys. Your pounding them and rubbing sandpaper over them. This causes blood in the urine giving it a very dark color. Cut your consumption down a lot and drink lots of water. Also do a little homework because it sounds like your killing the protein because you feel being on a cycle will aid in large amounts of protein synthesis. Being on a cycle does aid in this but not that much. The general rule of thumb is 2 grams of protein for every KILOGRAM of body weight you are. This can be adjusted up a little to mean 2 gm per every kilo you intend to be. In other words if you are 90 kilos (198 lbs) you would consume 180 gm protein a day. However, if you wanted to be 100 kilos (220 lbs) then you could effectively consume 240 gm protein a day. Now do the math if you were or are consuming 2 gm per pound of body weight you would be eating 440 gm a day of protein that's almost twice the upper limit of what you should consume. Now do this for months on end and you are punishing your kidneys! Hope your not taking any orals at the moment. Your liver and kidneys are getting pounded by Alistair Overeem brother. One more thing to add here; Your body is only capable of digesting 30-50 gm protein at a time. So if you are eating 100 gm a shot you are wasting most of it. 30-50 is because everybody's body is a little different. There are tests they can run to check your ability to synthesize the protein. Mine is a little higher then most but not high enough to consume 440 gm a day! Just keep in mind the 32 gm per meal rule and the 2 gm per kilo (not pound) and you should be fine.

Yeah whatever you're body doesn't absorb you pass in your urine, only so much will get used the rest is a waste.

Hard to get it just right unless your doing piss tests all day :-)

the real question is are you drinking over a gallon of water aday?
