Easy was factoring in the ester weight of cyp. But even then it's still short enough of 450 to be a pretty low dose
I think 100mg of prop EOD is like a background dose, it'll keep mood and libido elevated but from MY experience the actual muscle gaining power from a dose this low is going to be almost negligible... I was doing twice that dose my first time on test and i was very unimpressed.
I think if you are a first timer cycling injectables and using prop 100mg eod is a good place to start but once you're rolling I would say feel free to up the dose to like 150mg eod. That's 525 a week which is probably close to 600mg ew of enanthate which is about right for a first timer.
I think the # 500 ew is on the low side and 350 prop a week is even lower. Good for stacking, good for running a long time, good for a base, but as a standalone, probably won't make a huge amount of gains.
