*Help/Advice* Test C 500mg First Cycle

[Shute85]

Hey guys

I've done quite a bit of research thus far and would just like a bit of input on my first cycle. Making sure most if not all ground is covered and maximize gains before my fist pin.

Stats

Age: 30
Height: 5'8
Weight: 175
BF%: 14

Cycle
Weeks 1-12
250mg Test C twice a week on M/F

Weeks 9-13
250iu hcg twice a week (hopefully help in recovery and retain gains)

pct
Weeks 14-18
nolva 40/40/20/20

Gear is from Northern Pharma as well as hcg at an 10000iu bottle

My concerns are; do I need an AI during my cycle? or not necessary based on the low dose of test. Also what are everyone thoughts on introducing hcg during week 9 til one week after last pin of test before starting my pct? Should the length be shortened/lengthened or not even needed or kept the way it is? I've heard of people blasting HCG at the end of a cycle but unclear of dosage and benefits or risks from blasting.

Any thoughts and/or help is greatly appreciated. Just want to cover all bases and make sure I'm not running crap gear or crash hard and retain most of my gains. I definitely don't want to stumble first time outta the gate. I'm hopping to start pinning mid march just waiting on nolva before i do anything.
