There has been an awful lot of discussion about whether 300mg/wk is enough test for a first cycle. Nelson and some of the "moderate mods" have been posting for quite some time that 300mg/wk is a good first cycle. Those of us who have used much more have been saying to use more because the gains are so much more and the sides are pretty much the same.
Why would you go through all the hassle of a cycle, injecting, scoring, etc. and then settle on gains that you'd get at 300mg when you could DOUBLE your growth if you used 600mg/wk.
The standard reply from the low dose group has always been "you don't double your gains by doubling your doses".
Well fellas, that not true.
If you use 600mg instead of 300mg per week of test YOU WILL DOUBLE YOUR GAINS. No if's ands or buts about it.
Here is a link to the full study that proves it. Finally.
