RE: anavar sides
From what I've researched John, Anavar is widely regarded as the safest in terms of hair loss (which is another reason why I'm hoping to do this as a first cycle).
It can be run with Propecia/Finastride, although it does not react with the 5AR. So the finastride has no real effect on the Var.
From what I can tell, Finastride only really works with Testosterone and other AAS which interact with the 5AR to help control the rate at which test converts into the more potent DHT (which if you are prone to MPB, is the horemone which largely responsible for hair loss).
Anavar does not convert to DHT or aromatize, so it is generally regarded as a mild drug.
However, if you are concerned about hair loss (which unfortunately is a possibility with all AAS or any drug for that matter)....you may want to run a "hair loss prevention stack" whilst on cycle.
Finastride 1mg (each day)
Nizoral Shampoo (each other day)
Topical Spiro 5% (each day, applied before bed)
Re-mox IV lotion (each day)
This should help control DHT/androgenic related hair loss from all angles.
I think if you are sensible with dosages and prepare your cycles probably, you should in theory be able to prevent any major side effects from occuring.
