This is a long e-mail so please bear with me. First of all each steroid has a different anabolic to androgenic ratio:

Anavar 484/24
primobolan 500/20
Dianabol 90/40
Testosterone 100/100
Winstrol 200/33
Parabolan 500/500

From this we can see that Para is 5 times more anabolic than Test, but is also 5 times more androgenic.

i.e. 1000mg of Para would be equivalent to 5000mg of Test. Ok there are some other important differences, eg. Para does not aromatise like Testosterone, but that is due to it's chemical structure.

Why do some people make great gains from using predominantly anabolic steroids while others make better gains by using the highly androgenic steroids?

I believe a lot of it is down to the anabolic to androgenic ratio and your genetics. Once you discover what ratio works best for YOU, then stick with it. If you want to stack steroids then make sure that they combine to give you the ratio which works for YOU.

Lets say your body works best with 70% anabolic to 30% androgenic gear. You want to stack two steroids. What will you choose? Test and Para - NO because this will give you a 50/50 ratio.

Ok you still want to use Test as it is pretty cheap in comparison to the other steroids. For ease of calculation lets take 1000mg of Test per week.

To get a 70/30 ratio you will need to balance things with a more anabolic steroid say Primo. Primo is 5 times more anabolic than test, but is 5 times less androgenic.

When I worked it out the value I got was 300mg of primo per week, in order to get a 70/30 ratio of anabolic to androgenic properties. So the combo of Test and Primo that would work best for someone who is 70% anabolic and 30% androgenic would be 1 unit in mg of Test to 1/3 of Primo.

Ok other genetic facters will affect how well you gain, like aromatisation, conversion to DHT, etc. but this just means that if you are prone to these other effects then you must be more careful what steroids you choose.

If you want my opinion on why the pro's are much better built than us, it is because of (a) Genetics and (b) they, or their Doctors discover what worked best for them early in their bodybuilding Career.

Some people say that Proviron, which is almost completely androgenic, can actually reduce your gains.
If a person was predominantly anabolic, then this would explain why they would reduce their possible gains by talking Proviron, as it would push them into a more androgenic state.

All the steroid ratios are in comparison to Test i.e. Test is 100/100 where as Winstrol is 200/33 which means, mg for mg Winstrol is twice as anabolic as Testosterone, but only one third as androgenic.

This whole e-mail is to try and make newbies who are think about using steroids see that just because some tells you that 1000mg of Testosterone per week works for him does not mean that it will work as well for you.
