Glutamine is more than okay.
Creatine can be a waste of time for some people. My belief is that seeing as how one of its major functions is to increase power output, someone who has a good solid lean bodymass will fair better than someone who who doesn't.
I remember an advert one time in a crappy mag with some 230lb snarling juicer saying he got 50-60lbs on his Bench Press using crappy expensive Celltech.
Word of warning, Celltech has 10g per scoop, not 5. I don't believe it's good to consume 10g at once in the long-term, even with cycling off, for the equivalent of 9 months a year.
Yeah that guy might have gotten those lifts, but you've only got his word for that. Pay him enough, he might just be the type of person to say anything you want, if it sells more Celltech.
If you were someone wih tgood lean bodymass and I normally quote a figure of around 170lbs+, then I would say you would get results that justified the price. If you were certainly 160lbs or less, then it's likely not to be the case.
Thee are some people who are non-responders and you can boost it's performance with something like Grape Juice, Gatorade etc etc, instead of water. It's a combination of Amino Acids, (3 from memory), so the Insulin spike from the Carbs would cause a potentially improved synthesis in the same way as it would for Protein shakes.
The other problem is cost. Kre-alkalyn costs more than Monohydrate, and CEE probably costs more than Kre-alkalyn, but supposedly it's better for the performance. Kre-alkalyn claims around 40% of the water retention of Monohydrate, CEE supposedly none.
In your case, I'd say go for the Glutamine, but the Creatine may not workout, so if you go for it and results are poor, then cest la vie as they say.
