Frontloading

[whitemahon]

The purpose of this thread is to provide some basic information on frontloading, including an explanation of half-lives, differences across esters, and recommended frontloading dosages.

HALF-LIFE BASICS

Each compound includes an ester that, along with other factors, controls the release of the hormone into the system. The rate of release differs by ester and is defined in terms of half-life. The average half-lives of esters are:

ESTER HALF LIFE (days)
Formate 1.5
Acetate 3
Propionate 4.5
Butyrate 6
Valerate 7.5
Hexanoate 9
Caproate 9
Isocaproate 9
Heptanoate 10.5
Enanthate 10.5
Octanoate 12
Cypionate 12
Nonanoate 13.5
Decanoate 15
Undecanoate 16.5

The half-life is the length of time (in days) to release half of the hormone into the system. For example, if 500 mgs of Testosterone Cypionate is administered, in 12 days, on average, 250 mgs of testosterone has been released into the system and 250 mgs of testosterone remains attached to the ester. In another 12 days, an additional 125 mgs (half of the remaining 250 mgs) has been released into the system for a total of 375 mgs released and 125 mgs still attached to the ester. The key detail is that different esters release the hormone into the system at different rates. Therefore, different esters require different frontload dosages.

FRONTLOADING

The purpose of frontloading is to quickly reach the target dosage to more quickly realize the benefits of the AAS. This thread provides instructions to reach 75% of the weekly dosage within the first week

Most people use, as a rule of thumb, twice the weekly dosage (double dosing) in the first week. That works well for esters with a half-life of 10.5 days or less. However, this does not work well for longer esters. Let’s look at EQ as an example. If the intended weekly dosage is 600 mgs, then the frontload dosage, based on double dosing, is 1200 mgs. Although 50% of the intended dosage is reached in the first week, 75% of the intended dosage is not reached until week 4. Without any frontloading, 75% of the intended dosage is reached in week 5. So, while ‘double dosing’ works, the effects diminish with increasing half-life.

EQ Double Dose Values at 600 mgs (1200 mgs in Week 1)

No Frontload
Released… % of Target
Week 1 153… 25%
Week 2 267… 44%
Week 3 352… 59%
Week 4 415… 69%
Week 5 462… 77%
Week 6 497… 83%

Double Dosing
Released… % of Target
Week 1 306… 51%
Week 2 381… 63%
Week 3 437… 73%
Week 4 478… 80%
Week 5 509… 85%
Week 6 532… 89%



The following table includes frontloading dosage to reach 75% of the intended dosage by the end of the first week. The dosages are indexed at 100 mgs / week. To reach your intended dosage, simply multiply the frontload dosage by your weekly dosage divided by 100. For example, if you wanted to run Testosterone Cypionate at 800 mgs / wk, then multiply the frontload dosage of 225 mgs by 8 (800 / 100) for 1800 mgs in week 1.

ESTER FRONTLOAD DOSAGE(mgs)
Formate 100
Acetate 100
Propionate 115
Butyrate 130
Valerate 160
Hexanoate 180
Caproate 180
Isocaproate 180
Heptanoate 200
Enanthate 200
Octanoate 225
Cypionate 225
Nonanoate 250
Decanoate 270
Undecanoate 295


Injections for Formate and Acetate are daily. Injections for Propianate are every other day. Injections for Butyrate are every 3 days. All other esters are administered as one injection at the beginning of the week 1. It should be noted that injection frequency does not significantly influence frontloading dosages.

Very good post. Should be a sticky.

Great post bro. I would stck it but if I stuck every thread like this we would have a full first page of sticks.

225 x 8 doesnt equal 800 and 800/100 = 8 225 x 8 = 1800 no dividing involved. great post and thread but the example makes no sense to me at all...... surely you just multiply the frontload value by weekly dose or am im missing something

 

[RickRock13]

Very informative post!

 

[Mekat]

awesome info, but wouldn't frontloading make all the sides of AAS use come on much quicker also?

In short.. .yes

I'm not an advocate of front loading myself

 

[MattJS]

Good info bro cheers!

 

[Mark One]

Although sides are inevitable, or would u think they'd be more intense depending on compound? Logically speaking one would think the outcome of the AAS effect would be greater for duration of time,no?

 

[nickb86]

hey rick rock would you ever kick start a test e cycle with prop instead of waiting for it to kick in or doing a heavy frontload of test e ?
any one else tried this, thanks

 

[stevesmi]

old thread but glad it was bumped.. i think a bunch of people on here (including vets) should read this.

i've had to argue about half lives with so many people the past year on here and i still hear the same BS about it.

the worst is the newb who says they did a 12 week cycle with pct and on week 16 they feel fantastic and recovered. as if after 4 weeks magically the long ester they took was out of their system then they decide since they are recovered they can jump right back on when all along they had never even come off .. doh!

use an oral to kickstart. its good synergy that way

 

[nickb86]

ok mate thanks i know what youre saying is true, BUT i havnt run test before and wanted to get a feeling for each substance while on and when one kicks in so dont wana stack any together at the same time,
I am not that keen on dbol or any orals really maybe try the new epi 60 but not staright away. Just trying to keep it simple and get a feel for each product.

Just theoretical really but was thinking of maybe kickstarting with prop and also ending with small doses of prop to aid for smoother transition into PCT whilst the longer ester clears, as the prop leaves the system faster.
Has any body tries this ? would it help to keep levels more stable and add to gains ?
any input appreciated

 

[nickb86]

what do mean good synergy steve ? just a figure of speach or do they accompany each other well in a special manner ?

p.s not trying to hijack

ok care to enlighten me any further ? like how they synigise together ?

Synergy means that the two will work extremely well together and compliment each other

you can do whatever you want, but I do like to kickstart when using long esters because I don't want to wait 5 weeks to feel anything.. so kickstart lets say epi, or dbol, or helladrol etc. by the time you stop them after 4 weeks your long ester will start picking up

the idea to end cycles with prop you can do.. however keep in mind on your last injection of a long ester it will slowly start dropping off on its own. so in reality its doing the work for you. if you are concerned about getting the juice out of your body quickly and don't want your cycle to go on a long time then use a short ester from start to finish.. when using a long ester you must go 12 weeks + to get full benefits or you are leaving out weeks of peak levels when things really get fun. with primo and EQ even longer.

yes some AAS do stack well together.

masteron stacks well with tren (keeps prolactin down)
dbol stacks well with primo (gives it a nice anabolic kick)

when you stack test prop with test E its stacking test with test. (although the different esters do make these different of course, prop will bloat less than long ester test.. read the article on isteroids to get more info on why that is) so i think stacking something else is a good idea, plus it gives you a chance to experiment with different AAS instead of running the same thing everytime.

would encourage everyone to always try different AAS and different brands to see what you react best to.

ok thanks steve i see what you say, if i were to run a test e cycle i would do MINIMUM 12wks but with 10 weeks of test and 3weeks at start and finish with the prop it would be a 14week test cycle. Thanks for the info tho mate was just abit curious as i maybe thought ending the cycle smoothly and instantly may increase it effectiveness. obviously you'd need to taper the dosages over the 1st 3 weeks and ending 3weeks to keep testlevels stable, just thought id bring this up.
I know dbol etc are the best stacking products but id like to see what each compound is like and feel their full affects so thought maybe i could get away testing two dif tests by this method and maybe it may benefit, just trying to inspire some thought and opinions.

My actaule cycle will be test e (Best pharma i can find) and maybe stack this with Epistane 60, what additional gains on top of the test would i recieve from the EPI ?
thanks mate nick..

 

[nickb86]

Oh and also would i be better be running the epi at the beginning like a dblo start or at the end ?
Also would i need the use of Aromasin if i were to to stack the epi in for 4-6 weeks ?
again thanks.....
