As a non-aromatisable, non-toxic and very safe AS, Primo is a favoured choice by many. Yet I can’t help but wonder if it really is necessary to use Clomid after a Primo cycle after having read some articles by Bill Roberts stating that Primo won’t cause that much inhibition as other AS!? I have never read or heard about this from other articles or profiles. Does Primo really cause inhibition of own test production and is there really a need for Clomid post-cycle? Hopefully I have misunderstood, but any clarification on this matter is appreciated.
