Just like Dylan said. The other thing is if you use infrequently say every other week for example there's really no need to adjust your test e c or p. tne has no ester so it's in and out completely in just over 24 hours. Now if someone used it a few times a week they might want to adjust their test. But I don't recommend someone use it so often. Well, at least for me because of the aromatization rate. Even with an AI I get puffy and itchy the fallowing day. With not having weight with an ester it aromatizes much much faster then e,c or p which have esters.
