If winstrol doesn´t bind well to the receptors
how can a stack consisting of winstrol and anadrol be effective (progesterone balancing effects aside) ?

I have the option of using 50 mg of anadrol with 50 mg of winny for the last 3 weeks of my cycle, an other option is 50 mg of dbol with 600 mg of primo - which is the better choice?

I should mention that I will be on a caloric restricted diet during this time.

are you comparing a) 50mg/day of anadrol and winstrol (700mg/week) to b) 50mg/day of dbol with 600mg/week of primo (950mg/week)?? I think I remember Brock saying that 350mg/week of Anadrol is comparable to 500mg/week of T in terms of gains. In other words, the 50mg/day of anadrol is tricky since it’s very good mg per mg.

I would use the primo and dbol. With that option you have both class 1 and class 2 roids and I remember Brock posting this chart comparing the efficacy of oral drugs:

To compare with 50 mg of A-50 (efficacy):

Dianabol (methandrostenolone)… 20-35 mg
Winstrol (stanozolol)… 30-65 mg
Anavar (oxandrolone)… 20-35 mg
Primobolan (methenolone acetate)… 100-200 mg
Halotestin (fluoxymesterone)… 15-25 mg
Methyltestosterone… 75 mg

So the dbol is a little more potent than either A-50 or winny, and when you add 600 mg of a class 1 steroid I think it will be a much more effective stack. In addition both winny and A-50 are 17-AA and primo isn’t so you’ll have less liver stress. Hope this helps.

It’s true that scientific studies show
these steroids don’t bind well to the
androgen receptor, but they do have some
binding. So let’s say someone is using
100 mg/day total of both, which is 700
mg/week. Especially when you consider
that the half life is longer than for
free testosterone, even though the potency
(degree of receptor binding per mg) is
lower, you still do have some significant
binding. It’s not as if your androgen
receptors are getting castrated. Might
even be somewhat over normal physiological,
especially since in the early stages of
the cycle you may have significant remaining
natural T as well.

But other steroids will give a lot more binding
than these do and you can get greater
total effect at the androgen receptor and
greater total mass gains by combining these

The fact that you can make good gains
without stacking a Class I is a testament
to the fact that the Class II anabolism
not dependent on the androgen receptor
is quite significant.
