Cell Tect and Phosphagen HP are crap because consuming dextrose with creatine at the same time is far from ideal. Studies have already proven that dextrose is absorbed faster than creatine. Once the creatine peaks in the bloodstream the majority of the insulin spike from dextrose has already disappeared.
Two creatine researchers, Steenge and Greenhaff have demonstrated several times that you should always consume dextrose some time after creatine. One example is the following studie:
'Protein- and carbohydrate induced augmentation of whole body creatine retention in humans'
Published in the Journal of Applied Physiology, Vol. 89, Issue 3, 1165-1171, September 2000.
Here is an excerpt from this study:
"The 30 minute delay between the creatine and subsequent treatment fluid ingestion (dextrose drink) enabled plasma creatine concentrations to rise above the Km for muscle creatine transport. Furthermore, we have previously shown that this procedure produces peak creatine and insulin concentrations at similar time points and stimulates muscle creatine accumulation in humans.'
You guys can be assured that all supp companies who sell a creatine/dextrose are aware of this but certainly would never make any effort to tell you.
