I have tamox from a "metal lizard", and nova from a "research stop". I wanted to mix sources incase one is bad. Would it be okay to run nova and tamox from the first 2 weeks then drop the nova and just run tamox at a lower dose?

Tamox: 20/20/10/10
Nolva: 30/30/0/0
Erase: 3/3/3/3
Lean Xtreme: 2/2/2/2
AI: PCS: 4/4/4/4

PS: please input on everything, Thank you.
