I used tren as an example as it usually has the most sides. When levels are fluctuating too much you will see more sides.Comparing test enanth and tren acetate is tough
....So injection frequency is determined by the pharmacokinetics of the drug you're using. Test e has a half life of around 8-12 days (most believe it to be around 9). It takes awhile for your blood levels to stabilize regardless of what drug you're taking (approximately 4 half-lifes).
So if you take 400mg test e, 10 days later you will have 200, 10 days after that you will have 100 etc etc. the reason it kicks in after several weeks is because all of the half lives from the previous 4 weeks build up in your system and stabilize at the dose you are using.
Half life is 5.5 days, active life is around 10.5 days. These are not the same things.
I was using it to demonstrate how fluctuating hormones can cause you to have more sides, not comparing test to tren.While your point about tren does make sense, it really only applies to tren. Tren has a much shorter half life and kicks in faster. The shorter the half life, the more acute the effects and the more susceptible that drug is to fluctuation. Because tren works very differently from test e, it can't rly be compared. I'm sure injecting ed is dif compared to eod but that is a very dif compound.
Research half life versus active life.Basically, assuming you are injecting into the muscle belly and not going into blood vessels, the test e will decrease slowly, and once you have stable blood levels, injecting once a week is all that's actually necessary. If twice a week makes you feel better--go for it.
Misinterpreting definitions and trying to form arguments based on those misinterpretations is hardly science.But based on the science, it isn't necessary
