Maybe threre is something to be said for frontloading Tren

These charts and graphs would show Fina's Halflife - courtsey of bellx1 at FG -

This graph is a comparison of 150mg EOD without frontloading compared to 150mg EOD with frontloading at 150mg for 4 days. This does not represent a planned cycle, but just a theoretical graph of tren blood levels based on a 3 day halflife in a perfect world for 23 days. These are based on mathematical calculations, and results will differ from body to body.

The black line shows the average amount of trenbolone acetate in the blood after 150mg EOD injections. The red lines shows the average amount of trenbolone acetate in the blood after frontloading at 150mg for 4 days and then maintaining levels at 150mg EOD.

Without frontloading, serum levels do not reach a maximum, steady concentration until day 14. With frontloading, trenbolone is injected at a faster rate than it can be destoyed. Using the front loading technique, serum levels reach a steady maximum at day 4. While one group of people start their cycle without frontloading and are forced to wait two weeks for effective serum concentration, those who frontloaded enjoyed high levels of trenbolone in less than a week. Clearly, frontloading provides a ten day advantage over non-frontloaders.

Instead of waiting for the effects of high blood levels over the course of two weeks, the frontloader enjoys immediate results.

This information is based on an estimated 3 day half life of trenbolone acetate. If a normal person were injected with 150mg of trenbolone today, three days later that person would only have 75mg left in their body. Three days after that, half of 75mg would be left. This results in an exponential reduction in serum blood levels.

Thanks to onepack for the idea of graphing.

150mg ED for 3 days
75mg ED for rest of cycle

You will have constant blood levels within 3 days

Those graphs are the exact opposite of what you need to look at. They graph the amount of tren in your blood that is still attached to the ester. In other words, it graphs the amount in your blood that is not available for use. More interesting are graphs that show the amounts your body can actually use.

Zyg has some old graphs that showed the same thing, although he was trying to show the difference between ED & EOD injections only.

wow, now that is sweet! i don't have time to get into this more as i just got up and i'm heading to train, but JA this is an excellent post and i thank-you for posting it.

One last bump..

The problem with these graphs as stated above is that the tren is bound to an ester that breaks down at roughly 50% every 3dy. so on day one you don't have 150mg active tren in your system, you have more like 25mg with 125mg attached to an ester stored somewhere in your fatty deposits. Then after some carbons get cleved off somehow and a few more mg get released to be rapidly metabolized, bound or otherwise used. So therefor, its more like on dy1 you have 150mg of unavailable tren floating around in your body, then by dy3 you have used 75mg with antoher 75mg still bound to ester and unavailable. I am not sure if the end result is much different though. You wil still end up moving the peak release rate forward by front loading you will just have a few more days of ramp-up that isnt shown on these graphs.

Bump for more.
