Not at all. That's what the ester is all about.
Drugs do not enter an leave at the same rate. Some drugs are effective in seconds, that doesn't mean its effect leaves just as quickly.
Propp is only active for approx 40 hours. Are you saying ALL testosterones are only active for that long but testosterone enanthate takes weeks for that period to come into effect?
testosterone enanthate and testosterone propionate and all testosterone esters are inert. They cannot increase serum testosterone levels until esterase removes the ester which only happens in the bloodstream.
If you did a single injection of 100mg of test propionate (79mg of testosterone), it will somewhat gradually enter the bloodstream where esterase will do it's thing and leave free testosterone (which is the active drug in this case). Any particular molecule of free testosterone has a very short amount of time to provide any benefit because it will not survive a pass through the liver (which filters all your blood about every 30 minutes).
So the test prop is slowly entering your blood, being de-esterified and then destroyed by the liver. The serum level will peak, then gradually drop being somewhat back to normal after 40 hours when the 100mg you injected is gone.
If you inject a single shot of 114.5mg of test enanthate (the same 79mg of base testosterone) it will enter your bloodstream more slowly, the peak serum level will be lower than it was for test prop, and it will take longer for serum testosterone levels to return to normal. If you had a graph of serum testosterone level vs. time for both cases, the area under both curves would be identical because you injected 79mg of testerone in both cases and that's all you had to work with.
However, the 100mg of prop lead to a higher peak serum level (as stated) and it happened sooner than the peak did for enanthate.
For the same reason, if you start injecting 100mg/day of test prop, your bloodstream will start seeing 79mg/day of testosterone about a week sooner than if you start injecting 340mg of test enanthate E3D. All you have to do is put the relevant info into roid calculator and look at the resulting dosage level graph.
I'm not saying that test enanthate doesn't increase serum test levels almost immediately, I'm saying that it doesn't increase serum levels as quickly as test prop does. Since the effect of testosterone is dosage dependent, that has to make some difference.
