I think you are right - at the doses you currently use, if you were going to get a problem sexually you would have - i would say that even if you weren't injured that increasing the doses is HIGHLY likely to cause the problems you mentioned, let alone the fact it IS a waste if you cant hit the gym as hard as possible.
I use roidcalc. it is a good tool and a quick way to calculate my frontloads.
As for dosing frequency; it is the fact that test 9and AAS) exert their best results when there is a stable blood level. This is proven.
When one doses orals this becomes massively noticeable. When you take one dose of a longer oral such as drol in the morning, sides and results are much below what you get when you split the doses, this is due to the build up of drug in the system in the latter fashion - where the former simply rises the blood levels then falls to nothing.
Same for dianabol but even more so.
Winny isnt as noticeable as its effects are so small!
Same goes for injectables but in different timeframes.
As you can see in roid calc, when you inject 2x/wk (which is what i do) the levels rise and fall over a 3-4 day cycle (IIRC) and vary minimally. When one injects once a week - only one injection less, the levels fluctuate over 7 days in quite a large way. this means that levels of estrogen (due to aromatase) and other hormones (prolactin, progesterone) will all increase massively on injection due to much higher blood levels from injecting 500+mg at a time, and become dominant over the week progression and concurrent decrease in androgen levels - compared to the 2+ times a week dosing, where levels are much more stable and test stays dominant, and where only 250mg or less (for a 500mg week cycle) is injected at any one time, reducing affinity for aromatase etc.
Does this make sense? I know what i mean, but i struggle to convey it to others commonly.
As i mentioned in an earlier post - it isnt really the increase in gains from 1 pin a week to two or three, but a decrease in side effects.
Not only estrogen based sides from more test aromatised, but sides from the higher doses of androgens in the system at time of injection, when compared to the spacing out of the drug - so aggression, oil/acne.. whatever.
