First off, if you noted in my response i do not recommend anything over 12 weeks and gave myself as an example running a stack for 10 weeks. I do not think it is effective to run it longer then 12 weeks. Also i consider mega-dosing to be anything over 9 pills. So a 12/15 scheme is megadosing. So I do agree a 16 week megadosing scheme where the individual is megadosing for over 12/15 for 8 weeks may not be cost effective. But if he wants to do it, I have yet to read anything negative and if he has the funds then it is his choice.
But he did ask if he should stick to 12 weeks and I still believe that would be wiser and more cost effective.
As far as offering examples it would be my pleasure friend, i can quicky name one off the top of my head:
This is the second time this athlete mega dosed(at least the 2nd). And as you can see he is going as high as 21 pills on workout days.

As far as offering more examples, i would need to search through the archives of AM. That may take a minute. So if you really want it I will be more then happy to find some.
When it comes to Prime being the exception, Prime has several effects on the body including increased nitrogen retention within skeletal muscle. The more nitrogen retention, the more anabolic the body becomes naturally. So Megadosing possibly increases the bodies ability to maintain high level of nitrogen to keep the body in an anabolic state. Also Prime is believed to balance the body in times of stress. If the body is better able to cope with stress, stress hormones like cortisol are better managed(and we all know how catabolic cortisol is). Better stress management, the more you can excell in the gym. Also the herbs in Prime have been noted to stimulate and protect the liver, increase strength and recovery, promotes appetite, and is an overall means of making one generally healthier. So since no negative side effects are noted, taking in relatively higher amounts of this will yeild more benefits.
Now there is a finite curve of effectiveness so there will be a point where u will stop receiving benefits and start to level off. SO downing a whole bottle in one shot one give u super human health and strength. But increasing dosages over a short period of time can be of some use. Which is why i mentioned 8 week cycles ideally increasing in dosage little by little ending like Dreamweaver is doing.
And remember excess vitamin C is peed out, and something like excess protein is stored(which you did not bring up but is a common point made that ppl overdose on protein). And as far as exceeding recommended dosages...the daily recommeneded dose for vitamin C is 60-95 mg(
http://lpi.oregonstate.edu/infocenter/vitamins/vitaminC/)...which i have personally taken up to 6000mg of vitamin C without any negative side effects. And I bet most athletes take at least 1000mg daily. I know I personally can take 2000grams daily for months on end and i note i stay healthier and recover somewhat faster. Beyond that if i dont drink enough water i have very concentrated urine. So there are many "supplements" that are megadosed throughout an athletes career to yeild benefits. A common one is creatine. People dont need more then 2-5 grams of creatine mono daily but there are well trained athletes that take up to 30-40 grams daily with no negative side effects besides maybe some creatine bloat.
Again good sir, your attention to the need for moderation is a valuable trait that will keep you in this game for a long time. I do not condone reckless supplementation. I personally may be a bit reckless during my training sessions but that is something i am working very hard to rectify. So I PRAISE your asking for more info to validate my statements. If you want more logs I will happily look them up.
AND if by any chance I am mistaken, I ask a USP rep to PLEASE correct me so that I myself may gain more knowledge and not lead anyone astray.
