Hey girly.. so you are coming over to the darkside eh

ok.. if it were me personally, i would toss the tabs you have and cough up the money for some zambon tabs which are 2.5mg or even some Denkall Stan 6mg tabs... that way you can start at 5mg ED for the first week to see how you fend (this will be your 1st cycle remember) and then you can bump it ou to 10mgs ED...
However... if you are set on those damn 50mg tabs...spliting it 4 ways will get you roughly 10mgs a day, but accuracy is nill here... however you can split it in half and do 25mg E3D for a cycle... you should be ok and that will make it easier... when i ran injectable winny i did 25mg E3D and the sides i got were achy joints and ACNE!! but i got leaner and more vascular...
If you get the anavar.. stack it.. that would be a great cycle!!! drop the winny dosage down a bit and run the stack!! when and if...
As far as your joint suppliment, considering the fact that i had problems with winny and my joints! My knees and elbows were killing me, YES i would keep up your Glucosimine and condroitin (sp) to try to counteract the drying of the colaganese...
I ALWAYS use silymarin aka milk thistle when i run an oral.. me personally i would rather be safe than sorry and orals can be harsh on your liver and kidneys... i also drink come of that awesome new white cranberry juice.. that too helps cleanse...
Another note.. keep an eye on your cholestrol (esp if you are prone to high) as winny tends to raise it a bit...
so there ya have all my $.02

PLEASE keep us up to date on your doses and progress
luv super
