Wanting to start a cycle

Hi guys, im a 26 year old male who has been training for 6 years bulking and cutting and I’m sick of losing all my size on my cuts, I have just come to the end of my bulk and want to get on cycle to maintain my strength but get lean doing so. What is the best amount of test to take so I don’t ruin my natural production. I was thinking about just taking anavar but I’m really not sure what to do.
