I'm not in a position to look down at someone for using performance enhancing drugs when they shouldn't be but then again there isn't an option to have tested and untested bodies in my sport.
Test cyp has a detection time of 3 months so your cutting it fine. Test prop however is 2 weeks.
My recommendation would be test prop (2 week detection time), master on prop (2 week detection time) and anavar (3 week detection time).
Remember that you have to come off for the show. You can however go straight into a sarms cycle if you want as I doubt they're tested for at your level.
