Taking butt shots immediately boosts you over normal range.
You dudes seem not to understand how this shit works.
If you are doing TRT via shots - you instantly put a huge amount of testosterone in your body and your levels are huge - I go up to 3500ng/dL which is 5 times the normal for my age. Then the testosterone starts to metabolize. This takes time and you go from your peak to baseline over time depending on the initial dose.
However you do instantly reach a high level of testosterone in your blood.
The idiot who says that you need 5 weeks to reach high levels has no fucking idea what he’s talking about. That’s how SSRI affect serotonin levels - it takes a month for your serotonin levels to go up to their expected values BECAUSE you are not putting serotonin in your body, you are instead stopping it being taken up and removed by your body, meanwhile your body is still producing it. This is also how some other depression drugs work. However testosterone works like a nice Xanax pill, instant effect.
