hei there, 
as a pro m.m.a fighter i would like to share with you my experiences through all these years, so i like to begin with weight in and Pre Fight Pounds before the match, i think this one helps a lot very useful http://forums.sherdog.com/forums/f15/wei.....ad-450596/ if i remember right for the Kickboxing armature i think they dont dopin-test you guys 
for more info IMO 3 days before the fight lower your carbs as low as you can to weight in, but dont cut everything off just keep it low the reason here cuz 1 gram ofcarb holds 3 grams of water makes it very easy to lose weight fast, The weigh in are also usually the day before the fight and then after the weight in you have 20-30 hours to reload ur weight star reload as much mixed carbs fast and slow carbs, slow carbs at morning and mid-fast carbs 3 hours before the fight to get that crazy boost of energy, and 45min before the fight 2 scoops of craze and 1 scoop of Green MAGnitude if u buy it, but if the weight in is in the same day then u will find more info on the website above dont forget the 2 hours sauna day before the match to lose that water weight 
anyways, about cycle and supplements i highly recommend to add something like Green MAGnitude very powerful creatine complex i think this is the best creatine for fighters it contains Betaine Anhydrous Helps enhance oxygen transport an Helps to reduce lactic acid enhances power and endurance, it really works wonder i use it all the time if you buy it for example or any kind of creatine stop using it 7 days before fight cuz it can hold on litle bit of water and for your cycle it should look like this:
anything that u use all the time ur body get use to it and its not working as it should then u must increase the doses or change the whole supplement or cycle it shock your body to grow im sure i forgot something but feel free to ask cheers m.m.a finland
