dangerous compounds in swole/v12, truth or t-mag progagated bunk?

[OmarJackson]

I don't know if you guys remember an old t-mag article which claimed that certain compounds in products like swole and V12 such as Guanidinopropionic Acid could cause your body harmful long term effects in regards to natural creatine production. Well anyway, i got to researching to see if this had any truth based on the experiance of swole/V12 users and found no such imformation. So basically i'm asking

Have any of you that have gone through at least 1 whole container of either swole or V12, and then discontinued use experianced any negative side effects such as diminished strength or endurance?

here's the original article.

I have done both, I got great strength increases with Swole V2, but i dont think V-12 turbo had that in there, but my strength did increase just not as much as Swole.
