I'm not sure why people keep thinking a particular dose of anything has the same effect on everyone - that's b.s. Whether test, supplements, food, Xanax, allergy meds or pain killers. Metabolism and half life's represent a small sample during testing of a drug - they are means, not exact.
At 200mg t cyp a week I was under 500, and it wasn't bogus test - sandoz t cyp from the pharmacy. My doc had me on 400mg/week and I wasn't even at 900. Granted it wasn't an optimized protocol but tweaks me when I see stuff like 'there's no way' - that's the friggin problem we're battling with doctors and getting OPTIMAL TRT. How many times on this forum we see ppl asking for help because their doc will only prescribe what's normal?
Sorry for the rant but c'mon guys don't feed into the problem we all want to solve.
I have to confess that I was one of those ppl saying no way your at 900 w/ 400mgs a week.. I think youre right DES.. I read posts all the time now with ppl taking what I considered high doses of test but they were still mid-range.. Although, as you stated above, the correct protocol will definitely help guys get their test levels higher w/ less exo-test needed.. shbg and estrogen control is crucial
