Bearded gave great advice. I'll just offer some slightly different advice. Yeah a gram of primo will make you hold some water where it wouldn't at a lower dose. Still, with that cycle for 16 weeks you should already look really damn good. So, if you just wanna look peeled then drop Primo to 500 and add 500 mast. The winstrol is unnecessary.

Oh and mast won't overpower primo. They're actually very similar compounds. Main differences being that primo is a little better at building muscle and mast makes you shed a little more water. Mast is also a little harsher on hair for some people.

Drop the primo to 500 the last few weeks when you want to harden up and add the hardening agents.

Primo doesn’t hold water right? But at a gram it does. It’s minimal compared to what a gram of test or deca would hold but it still causes a little retention at that dose. So you drop to 500, that’s right around where you’ll keep a lot of the roundness but drop any extra water. Mast dose looks fine, I might do 400 and drop my test to 150-200 during that time. It’s a great way to polish off a primo run.

Winstrol I would only run if I was stepping on stage.
