Friend gave me more winny tabs, can I use them?

I am currently on my second week of my 6 week clen/t3/winny stack with clen 2 weeks, eca 2 weeks, clen 2 weeks. The planned dosage for the winny (tabs) was 50 mg ed, however, my freind just gave me 25 more tabs for free. I am 6 foot, 260lbs, and have about 40 lbs to loose to be completley solid. This is my first cycle. Would it be a terrible idea to run 100 mg ed for the last 3 weeks of the cycle? If so, why is it not a good idea - because of joint pain and liver damage?

I am also curently taking:

Tri-Flex (for joints)
multi-vitamin
calcium and potassium
Metamusal (on atkins diet)
taurine (for clen)
and milk thistle for my liver.

Would it be a bad idea to make use of the extra tabs?

Anyone?

I'd stay with 50mgs/ED bro. 100mgs/ED is just a little too much stress on the liver, especially for a newbie. Save 'em for your next cycle.
