Prescribed Dosage vs Stable Blood Levels?


#1

have been asking this on several boards and can't seem to get an answer...

What is the relationship between the amount of test you take and your blood levels? (I know it varies person to person, but in general...)

For example, if you are taking 125 Test Enanthate per week, what are your stable blood levels looking like at that dosage? And how are you feeling, especially towards the end of the week (just prior to next injection) when blood levels of test should be lowest?

There is no simple answer. It depends a great deal on your metabolism and genetics. The only way you can know is get blood drawn for labs and see what happens.

One thing I can tell you is that if you inject once a week, you will get peak serum testosterone about 48 hours later, then you will feel a "slump by the 6th day. Because of this, many divide their doses and inject every 3 or every other day, to keep things more steady.

PM me if you would like leads to more info that you might find helpful.

…not exactly what you asked for, but it’ll give you an idea of the amount of esterfied TestE after weekly 125mg injects. Notice the swing in levels from Injection Day down to the day before the next inject. This is why most of us are doing E2D or E3D schedules, it helps prevent these drastic swings.

Here’s a link to the Cycle Data Calculator:

ps…when doing weekly injects, Dr. J has his guys injecting 250iu of hCG on days 5/6, 13/14, 20/21, and so on. It helps out with those end of week lows by giving you natural T levels a little ‘boost’…hebs

Cool hebsie. I use http://www.roidcalc.com to get relative availability…
I agree with bigdawg, everybody is different.
One of my friends hits 800 TT on 100mg/week, and another hits 1700 on 100mg/week.

After being on HRT a long time (and many blood tests later) you can calculate where you’ll be fairly accurately.
That said, my prior statement is only valid if all ancillaries drugs are the same dosage, and SHBG, and DHT, and E2 levels remain constant throughout the course of treatment.
