Ok thank you very much for your help, would takeing it 3 days prior to the test help? It has 1000mcg of creatine 202mcg of B12 and 80mg of riboflavin, or is this Magic potion 100%useless shoulda payed my phone bill instead?

while there is no upper limit for the creatine, what is the lower limit, everyone is talking about taking the 500mcg pills whereass i have this powder muxture? Am i wrong in assuming 5g=500mcg? ((and this is creatine monohydrare, dont think it makes a difference))
