They dont work...
ALL Liquid creatines are in-effective!
In issue #80 of Muscle Media 2000, which I have right here in front of me, did a independent lab analysis of MMUSAs product. HPLC (High Performance Liquid Chromatography) revealed that the product, which claimed 2,500mg of creatine per serving, actually contained 1%. Lots#0124-610 and #8822 contained less than 1 MICROGRAM, and over 2g of creatinine. Very different from the 2.5g claimed on the label.
The standard dose application of liquid creatines is between 5-10 ml once a day. That means at 3.5 grams for 600 ml, you are getting exactly 0.029 to 0.058 grams of creatine a day, for a duration of 40 days, when for less money you can 90 days worth with 10 grams of creatine for 85 days and 20 grams for 5 days (for loading). + transdermal absobtion has a roof of 25mg , you need atleast 5g for a decent dose.
