HYPER-HYDRATING EFFECT OF CREATINE AND GLYCEROL
Maintaining adequate hydration is critical to perform optimally and adapt to training. Exercising in hot and/or humid conditions puts athletes at risk of becoming dehydrated, which can impair performance even with small water losses. There may be additional benefits to hyper-hydrating, which may provide for a more anabolic environment for muscle cells. Beside water ingestion, there are few dietary strategies to augment water retention. Creatine accumulates in muscle cells and thereby causes retention of water inside cells. Glycerol also has been shown to augment water retention primarily in the plasma. The combination of creatine and glycerol therefore has the potential to hyper-hydrate more than each supplement alone. A recent study compared the individual and combined effects of creatine and glycerol supplementation on total body water. Creatine supplementation (22.8 g/day) and glycerol (1 g per kilogram body weight) each increased total body water, but the combination resulted in the greatest hyper-hydrating effect. The effects of this water-loading combination on long-term adaptations to training was not addressed, but would be interesting to examine in future studies.

im planning on using glycerol straight after my weigh in on the 11th. Chances are i will be in a depleted dehydrated state at this point, how much would you reccomend me taking on that day and the followin day at comp..

1g per kg??? Is that right KP?

Experimentation would be wise ash. I've always used the old 50gms recommendation a la Dan Duchaine (he popularised using glycerol in the early 90's). Pre-workout I probably use around 15 gms when i remember...

Is it banned under some federations i read somewhere?

yes sireeeee

I'd experiment with the 1g/kg . Some in house studies were done by EAS around 10 yrs ago and found it through up a few anomaly's re blood pressure.
