Lower test with higher whatever else youre running will NOT be a problem as long as test is present at at least trt doses and all other levels (estro, prolactin, cortisol, etc) are controlled ... use your deca at whatever dose you want and your test at whatever dose you want, if test is high enough to aromatize or you are taking something else that aromatizes or you are simply prone to estro aromitization, run an AI. Run caber or prami the whole time or save it for if prolac or cortisol become elevated, i prefer to run all through. You will be fine. Personally, the only reason i ever see to lower test for a period is so your blast will be effective at the same dose as it was last time instead of needing to increase it from the blast dose youve been running.. if youre just cycling or coming off a cruise and will be going into a cruise after, keep the test at a blast dose as well to maximize gains IMO... its cheap and extremely effective.. you wont have any extra problems either way so long as othee hormones are controlled, but test is great for size as well.. only time i wouldnt run high test like i said is either to cruise or give it a break so that its more effective when raised back up to the same level.
