yeah man i usually dont post studies because i cant be arsed digging them out
i read quite a lot on pubmed etc and usually remember having read something somewhere but i rarely ever save links
i agree on the dosage thing, however a normal male allegedly produces between 3 and 15mg of test a day or so
so that would make 105mg the highest upper range
with exogenous test this seems to be a bit different though because ive never seen ANYONE who gets high test readings from 100mg a week.
including cyp/e ester weight that would be about 130mg a week.
from what ive seen people "need" around 150-200mg a week to get into the upper normal range.
but of course we as bodybuilders have a different metabolism, more muscle mass, more blood volume etc than the "average" guy who produces 5mg test a day
note i was talking about the 250mg every two weeks that falco recommended aswell

250mg a week would certainly not be HRT anymore but a cruise protocol... however youll still be on the low side after the first week with 250mg every 2 or 3 weeks compared to the equivalent amount injected twice a week.
of course your test levels will be much higher (too high for true hrt aswell) during the first week and then too low during the second and third week. this is plain stupid.
nonetheless i dont think less than 100mg a week would be a sufficient trt amount for anyone
(maybe with the exception of the emeric protocol on promuscle, where u inject just 10-15mg ed, which seems to yield much higher levels than once a week injections because of much less aromatization etc)
