IMO Dont even bother using it for 2 months, you will be disappointed. Using it with slin is a great idea, do more research though , you gotta stack it with test, run slin, run cytomel, and NEVER take 2 days off. I have used it plenty, and I usually run it for 4-6 months, IMO if you cant run it for at least 12 weeks, your money is better spent elsewhere. Oh yea 6u.i.'s a day.
