"..I know an injectable would be a much better option in terms of cost/benefit.."
I personally would choose Dbol to stack with Var, while BR DOES say that Stan is also CII, there is going to be a better overall effect using a drug like Dbol with a CI like Var. IMO at least - clearly he would be the man to consult having done synergy testing/experimentation.
I too think you should use an injectable - if your weekly Var costs less than 500mg/wk of Test E, then you should possibly distrust your source.
Var will also be considerably more expensive than Winstrol or Proviron and if the addition of either of those drugs makes the cost double, i would again seriously doubt the quality of this highly faked drug.
Proviron has no useful anabolic effect and would only be useful for the DHT - and there are other drugs that do this but actually give other benefits too (Test'one, Mast'on). For this reason it has no role in class synergy - as it has no noticeable anabolism.
Winstrol and Var are both relatively mild steroids in men, and while BR suggests there is some decent synergy (never stacked them - fucking hate Stan) - there is still a 'glass ceiling' due to each individual drugs potential.. so bear that in mind if you expect an explosive combination of any I+II stack.
If the beleif is simply that it will be better - then that is right.
As i said, if i were to do an oral cycle - which i would not, then i would use a Class II like Dianabol or Anadrol stacked with an effective CI steroid like Anavar or high dose Primo (200mg/wk).
I prefer Drol on many levels these days - and think that with HCG, that a drol and var stack would prove very nice indeed for a lean gain in quality muscle (i thrive off controversy ).
I have in the past listed a 'wish-list' favourite oral cycle to be:
Wk1-6 Primobolan Acetate 150-200mg/day
Wk1-6 Dianabol 30-40mg/day
Wk1-6 Anavar 60-80mg/day
I think that would be real effective.
