I am surprised nobody mentioned that Anavar increases the Atp cycle making creatine more effective and creatine making anavar more effective at raising strength and endurance. And intracellular retention of glycogen would be increased to. But I would personally not take creatine with something like testosterone for the simple fact it would raise water retention more and there for raise blood pressure more on top of the increase in blood pressure testosterone already gives you. Also I would suggest not running any steroids with out a basis of testosterone to the guy who said a tren only cycle. Your body does need levels of testosterone to function at a healthy basis and a tren only cycle will shut your natural testosterone down. Also I would not advise running tren for a first cycle. If you wanted to stay lean I would go with hormone replacement levels of test P combined with something on the lines of anavar or primobolan. A very expensive cycle either way but you would enjoy the results more than a test c cycle and looking as bloated as a hot dog contest eating winner. lol yes yes I know Ai's can lower water retention but you will still bloat a little at a normal 500 mg a week test cycle. And if he likes a hard cut body he will notice that more than your average joe. This is all theoretical advice though don't take my word for any of it consult a trt doctor or something.
