Eh bro, why not hit a gram but at a different ratio. Try Primo at 700/wk and test cyp at 300/wk. You are still mostly anabolic with some of the test benefits in their as well. maybe a kickstart with some dbol or var as well if you wanted. I personally wouldnt run anything for 20wks., just because I have seen it happen to many bros, and your gains just start diminishing after 10-12 wks. Even less for me, my cycles now are 8 wks max. Is it worth supressing yourself longer for another 10-12wks (3 MONTHS), for an extra 5lbs. when you could take the time off and run it again fresh and add 15lbs instead.
Take these 2 examples for instance. Here are the scenarious. We will look at wk1 up to say about wk 50. Which scenario do you think will leave you with more of a net gain. In both scenarios you will be running 20 wks worth of gear. The first one is one long cycle, with 1 long time of, the second is 2 shorter ones with a shorter time off. At wk 50, which one do you think would have more muscle...
Option1.
Wk 1-20
Test: 300mgs/wk
Primo: 700mgs/wk
Wk 23-26
PCT
or...
Option2.
Wk1-10
Test:300mgs/wk
Primo: 700mgs/wk
Wk13-15
PCT
Wk15-25
Train naturally
Creatine
Glutamine
Try hard to maintain gains.
Wk26-36
Test:300mgs/wk
Primo: 700mgs/wk
wk37-40
PCT
By the time wk 50 rolls around, Im sure that you will agree that the person who runs the 2 shorter cycles will have more muscle. Plus he would have restored his HPTA in between cycles. Scenario 1 would probably have his test levels back up as well, but it probably took him a good 15 wks to get it back.
A scenario of the gains.
Option1.
Gains 15lbs of lean muscle in the first 10wks.
Gains only another 5lbs in the next 10wks
Net gain=20lbs.
Option2.
Gains 15lbs of lean muscle on the first 10wk cycle.
Gains another 15lbs of lean muscle on the next 10wk cycle
Net gain=30lbs.
Plus ... these gains are spread out over a longer time so the body has more time to adapt better to handling the newly added mass (2 chunks of 15lbs over a longer time, instead of 1 chunk of 20lbs at once). These are just ficticious numbers, but you get my drift? I think that the longer cycles are hindering your gains, where you could be getting more muscle by breaking it into more, and shorter cycles. Just my opinion bro.
