Yeah if you have a fucking vagina. Oral only cycles are retarded and should be taken with test as they will shut down your natty production. Don't give advice when you know absolutely shit.
But after a few weeks your test drops to basically zero. Guess how much muscle youll be building with no test?
No shit captain obvious. Everything will shut down natural production when you take exogenous hormones. That's the name of the game.
Instead of regurgitating conventional wisdom, do some reading on DHT, it is a much more potent androgen than testosterone (though less anabolic in muscle). There are also plenty of threads/posts/experiences from guys out there that have done anavar standalone.
Also, I'm in no way giving cycle advice, so no need to be a flaming monkey. I wanted to go on a quick cycle with little confounding variables and easy recovery, so I thought of anavar. We can learn from my experiences.
