The two are very similar in the term of results and what to expect. Anadrol is the stronger of the two but also more liver toxic. Everyone responds to drugs differently. Some people prefer dbol, some people prefer anadrol.
Both are very estrogenic and liver toxic so make sure to include an AI like aromasin and a good liver aid supplement like n2guard into your cycle lay out.
Definitely not anadrol. Deca will already cause prolactin related issues, and anadrol will make it worse. Besides, anadrol in general is quite harsh in terms of side effects, so I don't really see the need to use it and get tons of water into your body.
I personally wouldn't use Anadrol... It has some wicked sides, and it really really bad for the liver.. Dianabol - 30-40 mg for 4 weeks is all i would use for
They are both pretty harsh orals. There are many similarities and differences so just read up on them and make the choice. If it was me I would probably do a lower dose dbol but would definitely keep my test dose low. Maybe 300mg per week. You would be running 3 wet compounds.
