Can I add Masteron to my current cycle?

[Tigershark]

The cycle I am running now is:
Weeks 1-12 Testosterone Enanthate 300mg - 400mg
Weeks 1-10 Deca 500mg - 600mg

I am currently in my fourth week of this cycle and my girlfriend has decided to cut her mast cycle short. Can I add mast into my cycle for weeks 4 to 10 at 100mg every other day?

I would personally just stick with the plan you had, and wouldn't add in compounds just because they become available.

Thanks D7M will do.
