There are various ways to do this,basically you need to eliminate the stored metabolites of the drug,nandrolone and boldenone are quite stubborn and seem to hang around in the body longer than any other steroid.
Basically you have 6 weeks to clean your system,Countchuckula is correct with the oil change comment,if you are a drug tested athlete you should be using quicker releasing esters like Testosterone propionate and Winstrol depot they will leave the body much quicker if you are forced to end your cycle due to a test.
The idea now is to speed up the elimination process.
I conducted this experiment on myself a year ago.
I was taking 500mg Test 400mg deca for 10 weeks
Stop all the gear!!!!
I then stopped,no pct, but took 2ius of hGH daily along with 25mcg of T3
1.30 mins cardio daily,alternate between stationary cycle and running machine first thing in the morning before food.(Drink 2 of your alotted litres of water while doing stationary cycle)
2.Drink 4 litres of water with a little dilute or natural juice added (as this can become boring) spaced evenly throughout the day on day 1 of this program,then increase by half a litre per day until you are drinking 8 litres daily this has to be maintained for 4 weeks.
3.Eat clean, low fat low carb high protein lots of salad Tomato,celery,onion,lettuce,red green yellow peppers,cucumber etc.
4.Take 500mg Milk thistle, 1000mg Vit C, Vit B-Complex ,ZMA,Multi vitamin with breakfast lunch and dinner.Increase the vitamin C by 1000mg every 4 days by adding it to breakfast on day 4 lunch on day 8 and dinner on day 12 then continue with 6000mg daily all the way until test day.
5.Take a natural herbal diuretic from day one of this program there are various types Aqua Ban,Adios,Dandelion root
Water Pills - Available at GNC
and follow instructions.
After 4 weeks take a test you can buy one here
At HomeSteroid Test | Walgreens
It will take a few days to get your results ,I was clear after 4 weeks,if you aren't then continue for another 4 weeks on the program and retest.
Hope this helps
