Novice about to begin using but not sure which to use

Plug what numbers in where?

Lets compare Prop and Cyp:

Every 100 mg you inject, Cyp gives you 69.90mg of actual hormone and prop gives you 83.72mg.


For a 500mg/week cycle you get 349.50mg with Cyp and 418.60mg with prop.

Over a 10 week cycle you are getting 691mg more of test with the shorter ester. (3,495mg Cyp vs 4,186mg Prop)

Three days after your last Prop inj it basically has exhausted itself, compared to 10-14 days with Cyp. (see PCT Start times as another reference for this)

So in 10 weeks and 3 days you will have had 4,186mg of actual Test with prop. This considers a shot every day with the last one being at the last day of 10 weeks and having an effective release of 3 days.

In 11 weeks and 3.5days you will have had 3,495mg of actual test with Cyp. This consideres that you take Cyp every 3.5 days with the last shot being at 9 weeks and 3.5days and having an effective release over 2 weeks.

SO, how can a longer ester give you a higher level at anytime in the cycle when you consider:

1) Mg per mg you get more hormone with a short ester.
2) The hormone is released more quicky with a shorter ester.

If you get more in a less time, your peaks are going to be higher.

its not linear. google exponential decay. I dont have a calculator so you are going to have to punch the numbers in yourself but here is the formula if you are shooting 100mg of test p and 70mg of test e
test e
70*(.5)^(t/7)
after 1 week we would have (injecting ed)
70*(.5)^(1/7) + 70*(.5)^(2/7) + 70*(.5)^(3/7) + 70*(.5)^(4/7) +
+ 70*(.5)^(5/7) + 70*(.5)^(6/7) + 70*(.5)^(7/7)

the prop is done the same way. only instead of a 7 put in a 2. instead of 70 use 100
I think it will overtake in a week but it might take two.

You have to have your decays on actual usage. IE: Enen at 250mg every 3.5 days and prop at 75mg ED. (75 ED actually gives you 525 a weeks, so for apples to apples you should use 71.43mg/day)

Exponential decay does work to a degree, but it is not taking into consideration the actual amount of raw hormone. Unfortunately, with enan you get less effective hormone than with prop.

You are right, it is not linear at all. Everything you inject comes on in a wave. Which is why frequency is so important. the closer these waves are together, the more stable your levels remain.

I will play with your formula. I am not certain this is the right formula for this. Because unlike something like a radioactive isotope which has a predictable and constant half-life, the esters slow the release of the hormone.

What has to be considered is the actual release rate. Since, for example, prop slows by 2-3 days, it is not until day two or three that a particular injection has released all its hormone. You will get SOME release along the way, but the bulk of its load is released close to the end of the ester life rather than in the middle. So, I do not believe that we are dealing with a true half life here.
