id be willing to bet that one of your testo bottles is waay underdosed and fake... depending how long you've been on.
it sounds like you were on long enough to let the levels build up during the first test... but unless you have been on for at least 3-4 weeks, there could be a good chance that the enanthate hasnt kicked in yet and that would explain why you dont have the same peak that you did previously.
how long have you been on this cycle for?
if youve been on for at least 4 weeks, then id suggest sending your stuff to SRCS
if you've been on for that long, with your test results, id be wondering if your prop was underdosed or possibly just inert oil..
your test results sound like it could be right on target for someone taking 300mg of enanthate per week... though prop is short acting, if you shot 48 hours earlier, even after taking into account all the variables massive posted, your test levels should at least be near the same as they were during the last test.
taking into account your on twice as much test, and the fact 700mg of it is prop, which causes higher peak plasma levels, even just the 700mg prop IN THEORY should have elevated your test levels higher or at least as high as when you were on the 500mg of enanthate.
also it should take less time to reach the peak levels with prop, 4 weeks is definitely more than enough time for that IMO.
id definilely send the prop in to get tested... or you could bump your enanthate up to the same dose... if you notice a huge bump in results comparable or even better than your last enanthate cycle... id be willing to bet your prop is bunk
