i say keep the cycle short, end it now, do your pct. youre not using hcg which works against you, and taking test at week 8 will keep your test up (and supressed testes) until week 10 or so.
choice is yours, its a gamble. stay on longer, almost certainly get more supression, crash harder. or, end it now, keep a modest amount of gains, reset, then do another cycle later with hcg all the way through, with overall higher gains kept in all likelihood.
good luck either way
