scared of tits

I just picked up Andro-Stack, from Substrate Solutions. Each pill has
100mg 4-androstenediol
100mg 4-androstenedione.

After reading some old post on the supplement i just picked i am started to get a little freaked out about growing tits from it. Everthing I have read on the forum says that the “diol” is good but, the “dione” will give me TITS.
TITS are not cool on dudes. So I was hoping that some one could help me out and tell me what to take while I am on this so I don’t get tits.
Thanks for any and all help.
GET BIG. DA

some one please hit me up with some scientific facts on these 2 andros so I know how to avoid growing boobs the first time I try working out with some hormonal help.

i have an idea. dump the shit and get some mag-10!

I would love to except. I bought from a local store that I had a gift card at. They were out of mag-10 and wont be getting anymore in for a while. Besides that if I were to buy it from there it would be even more expencive than the store on this site.
So like I said please some one tell me about the stuff I have.

Are there any legal alternatives to nolvadex/clomid?
Or is ten days worth of 300mg of 4-androstenedione not enough to really effect me in a negative way?
