I think being a beginner the 5x5 is inappropriate especially the periodized version and to a large degree the novice/intermediate single factor version. In reality, you need to practice and learn the lifs. A lot of times that's a 3 day per week program where you do the same exercises every day until you get enough skill and a base to really push yourself. At that time a single factor program (a la the novice/int program) would be appropriate. A few years of similar work will get you to the point where a periodized program is going to offer you something more - until you are upper-intermediate, it's pointless and you might actually wind up with worse results.
The main Westside program also assumes a pretty solid base in the core lifts. You just aren't going to get as much out of speed and max effort work as someone with a few years of experience. Tim Harold Jr. gave someone the same advice not too long ago. You need a base first to really reap Westside rewards.

HST might be a viable option in the short term although even here, I think you need more work on the basics to even make the idea of a 15 or 5 rep max valid.
Your best bet IMO is still a 3x per week program squatting, pulling, benching, rowing, chinning, and overhead. Just get it all down first and get your base to the point where you can make use of the better programs.
As for as Max-OT...I certainly wouldn't put anyone on it but a lot of novices have been happy and it gives them a plan and progression to follow. Could be worse.
In reality a lot of the stuff being used here and in my thread isn't for beginners. I really don't have a great total beginner program in there and most of the stuff is geared toward intermediate or advanced. This assumes a good base, knowledge of the lifts, decent capcity for workload, etc... and it takes a few years building that. Even the novice program really isn't for beginners but for someone with a decent base and time training the main lifts.
All that said, 2 weeks isn't much to see results. You should read my post on Diet and the nature of caloric excess here:

Honestly your best course of action is to buy Rippetoe's Starting Strength, and follow his program. This is probably one of the best guys at adding mass to novices. Lots of guys have put on 30lbs their first 3 months. In 4-6 months it's pretty routine for him to get 30-40lbs. His book is here:

http://www.readthecore.com/200507/trenches.htm. He touches a bit on novice training but it's mainly bio. Next month he and Glenn are supposed to cover programing for novice, intermed, and advanced lifters.
Hope that helps. To be honest, the periodized program has gotten popular enough to find it's way to a lot of places where it's getting used by people it's not meant for. This is going to hurt them rather than help. As you can see, even the people that swear by this style workout and use it with outrageous success accross a broad range of athletes do not use it for beginners or novices (granted what they do use is another variation) and to be honest at a minimum it's a year of hardcore training (i.e. not BBer style) before they'd even begin to implement the basic periodized template.
