This won't be enough for both of you. The Nolva alone would last only one of you the first half of a proper PCT.
??? What are you talking about, "use nolva for HCG" - HCG is a completely different compound that is used to help prevent testicular atrophy on cycle. I can't answer the rest of that question because it doesn't make any sense.
How tall are you? 165 is really not very heavy....
Input: review everything, you need to do more research and probably wait a couple years. And 3 weeks of winnie with or without a PCT is a bad idea, but even worse without.
