As i said in my previous post, sorry for the delayed response, traveling and work can make things a bit complicated. In response to your questions:
1. The only negative side effect others have experienced (and i did mildly) was visual, I would see some spots when I'd go from a bright environment into a dark one. I found out that dosage influences this, so all i did was taper down the dosage, and it never happened again. (it only happened once).
2. I took this supplement on my workout days, monday through friday, twice a day. Once before each workout, and each dosage was about 30 mg
3. I would take it between 30-60 min before my workout, it has a 4 hr half life so I found it best to take it that way.
4. I took it straight, but beware, it tastes AWFUL, but i could care less about that.
5. One bottle lasted me a full 4 weeks (at two 30 mg doses per day, 5 days per week). I still have a little less than half of the bottle left over, so i'm taking 4 weeks off, and will start back up until i finish it off
6. I did not take any PCT afterwards, and this is my second week off it. I have not experienced any shutdown at all, and still feel great. Of course i don't feel as good as i did when i was on it, but i don't feel like crap either, it just feels like i'm not taking a regular supplement anymore. Def not the way one would feel after taking a cycle of test or any other 'roid for that matter.
Hope this helps, let me know if you have anymore questions.
