I have never had an issue with their ancillaries, or any product for that matter. I am their rep but, the same goes from the years I ran their products before I was a rep. Top quality all around. I am running their Aromasin right now and it is doing exactly the job it should be doing. Ive also ran their Adex, Nolvadex and pretty much everything else they have without ever an issue.
Hope this helps.
Any questions dont hesitate to get in contact with me.
