I have been maintaining correspondence with an employee (the owner?) of Mega Gear over the last few weeks, and he actually stated that most users report having the most productive cycles (in terms of strength/mass gains) over the course of ~12 weeks. Having said that, you might not really notice anything at all from taking just 2 vials' worth. Here is a link to a supposedly independently-written blog by a "bodybuilding coach" who describes the cycle experiences among several of his buddies who were each taking a ****tail of Mega Gear products:

I just glanced over his blog again and saw where he stated that they were cycling the products for 13 weeks.
Your hunch that these products could actually contain "the real deal" might be on target; the Mega Gear employee told me that individuals who administer the oil-based products via injection have reported gaining the most weight. Hmmm...
I do agree that the packaging seems to be high-quality and lends a notion of legitimacy to the products. Hell, the boxes even have authenticity holograms like you'd find on the tag on a shirt from Armani or something.
I can barely contain my excitement -- when I go to the gym on Sunday (or tomorrow if I can't wait), I'll take 2 or 3 Danabols (5 per day is what the employee told me to take) along with a few mL's of Testobol-250. I doubt I will feel anything, but I bet the placebo effect will more than make up for the lack of true efficacy.
