you're fine with the doses you ran... however, some guys use several GRAMS, which means it can take nearly a month to reduce to levels near what would normally be produced.
everybody says 14 days, because it's easier to plan that way. it's not like all the test is out of your system yet, anyway. you just want it to be close to "normal" levels so you can coax the HPTA into recovering...
just so you know, normal production is like 3-10 mg/day, which would be like 20-70 mg/wk.
your doses are 500>250>125 in 2 weeks, so you're still over normal production. (and this is just your most recent dose, not ALL the other doses you took prior...)
^anyway, you're fine to do PCT here... don't get all panicked and throw in a bunch more crap, as it's not gonna speed your recovery any more, and it might actually hamper it.
