Primo is slept on by alot of more aas experienced users I feel because they use compounds that are much stronger so they don't see the benefits in Primo, for someone like man05 and myself being newer users Primo is a perfect compliment when combined with other less potent aas, I put on 10lbs clean with my Primo cycle with low test back in october with low test , it has its place for people wanting to get into aas and starting in the shallow end of the pool.
