Looking over the pct article on this site, I noticed supertest 320 and sustanon are listed together and they are noted to have a half life of 18 days and therefore a waiting period (3 x half life) of 54 days.
For sustanon I agree with this as part of the blend is Testosterone Decanoate, which is quite a long ester.
However with supertest 320 the longest ester in the blend, is cypionate, which has a half life of 12 days and therefore a waiting period of 36 days.
It seems to me that supertest 320 should actually have a waiting period of 36 days and not 54 days?
