Sandman,
Hasn't much been said about Primo tabs, but they are essentialy non-liver toxic. Primo acetate tabs are not 17-AA (not alkylated), and therfore very safe for the liver.
I love Primo tabs for my oral, because they are so safe with literally no sides, and you can take for a longer period of time. Most bros don't talk about it (I think) because gains are indeed mild, not explosive, don't see huge strength gains, need to really take multi-doses per day, and are rediculousy expensive.
However the gains are absolutely top notch, best quality, with no acne, bloat, gyno concerns, emotional disorder, you name it......plus you can keep the gains for a very, very long period of time. I love it as my base stack, depot or tabs, but I cannot always afford it.
I would definitely recommend more than a 4 week cycle with Primo tabs, and I would recommend a minimum of at least 100 mg/day. This adds up fast $$$, but the quality gains are uncomparable IMO, and post cycle is great! Stick to EF more than the magazines like Retabolil2 stated, and please do not agitate him to post, his avatar scares me, just a little primo boy.
