Read this and you will have a better understanding of front loading. Also check out some of my other links.

I am at work so this is not my best work. I just commented on another thread on here and thought there was enough info here to warrant a thread of its own. I like to use analogies when I am trying to make a point so this may be right up some of your alleys and for others it may just be a big complicated mess. Either way enjoy. I hope it helps clear some things up.

Look at the compound your taking and think about it for a second. Test prop for instance has about a 2-3 day half life. What this means is every 2-3 days the injection is about half of what it originally was. The ester comprises about ~ 20-% of the injection. It is the esters job to keep the test inert until it is released or cleaved off from the ester and into the blood stream.

So imagine your body is a bank and you are depositing a compound (I will use money as an example), you deposit $100 dollars into this bank which lets you pull out 20% a day. Eventually your goal is to pull out $100 a day but you have to have enough money in the bank in order to get an average daily withdraw of 100 dollars. So for every 100 that is in your bank you are allowed to withdraw 20 a day. Obviously you need to have $500 in the bank at any given time in order to achieve your goal of $100 a day. The hundred bucks a day is your steady state and this happens at your peak level of an average daily amount of $500. Stay with me here. Now every two and a half days your hundred becomes $50 bucks so you must deposit another $100 bucks every 2 says or so in order to be able to pull a minimum of 20 a day. You with me. This is the half life or the steady decay rate we are talking about. Now given that on the 2.5 day mark we already have $50 in the bank it is obvious as long as we keep depositing money at a faster rate than we with withdraw it, it will slowly grow until it reaches a point that the amount of daily withdraw will be equal to the amount of the deposit amounts of $100. So at day 0 we deposit $100 and at day 2.5 we deposit another $100 adding to the $50 that is in there making it $150 and at day 5 we are depositing another $100 making it $175 that particular day and so on and so forth. I hope your still with me! So you can see that it slowly grows to a point where you would achieve a daily average balance of $500 allowing you to use $100 a day on average as long as you keep depositing $100 every 2.5 days.

I told you that story to set you up for this one. The amount of time it took you achieve your steady state of $100 a day was the amount of time it took before your cycle or plan "Kicked" in. The one thing I didn't really emphasize above enough was the decay rate or half life. This is a constant that basically means you are allowed to withdraw a percentage of the balance. To start with I said you could withdraw 20 for every 100. That represents about 20%. What this really means is you can withdraw 20% of the balance per day. So on the first day you withdraw 20 from 100 which means the second day you can only with draw 16 from 80. On the third day you can withdraw 35 from 175. You get the relative meaning here? You will have to build your reserve to the 0ver 500 mark to stay ahead of the decay rate. So what if you just built up your deposits quickly at the front of your plan so you wouldn't have to wait so long. Just deposit $500 up front and you would start out withdrawing $100 the first day! That would be nice right? By depositing the $500 the first two times you have front loaded the bank with your reserves giving you a head start. Now you can start enjoying the benefits of your steady state sooner than later.

However, we are dealing with biology and the human body so you can load the bank all you want and withdraw the 20% but your body is still going to have to have time to saturate with the compound. Your HPTA is going to need to tell your boys to shut down and nitrogen retention at the cellular level is going to take some time to kick in. This is the ever moving variable in the whole system. Everybody's body is different, but when your body does take to it and you start feeling the effects you will already be close to or at steady state allowing you the benefit of maximum gains with less amounts of gear and in less time.

Look at these two graphical representations of what I am talking about. One is not front loaded and the other one is.

Front Loaded:

Notice how the front loaded one comes down into the steady state.

IF you have read all this than kudos! I am sorry if I just confused you I tried to keep it simple.

For those of you that have a good understanding of half life and decay rates and also understand that the 20% ester ratio is only the amount of ester added to the base compound; I understand that the daily decay rate is not 20%. I was only using that number to keep it simple.

Thanks for reading.

Good reference for understanding the subject matter.
