6-mercaptopurine Purinethol, Does it hinder muscle growth? Bodybuilding.

Hey, I was wondering if any one has any information if 6-mercaptopurine (Purinethol) has any negative impact on bodybuilding/muscle growth?

I tried to google but didn't seem to find anything.
How ever this is all I could really find involving the words 'muscle' 'protein synthesis' etc I don't have much idea if this has anything to do with my question though.

"6-MP ribonucleotide inhibits purine nucleotide synthesis and metabolism. This alters the synthesis and function of RNA and DNA. Mercaptopurine interferes with nucleotide interconversion and glycoprotein synthesis."

And..

Thanks.

I took 6-mp while bodybuilding. Didn't notice any negative effects on muscle mass. Only thing I noticed, was horrible acne. You won't see the side effects like prednisone in your workout. I can't seem to make any gains on that stuff.

Good luck
