Ok here goes... I am going to first talk about the "active" Halflifes of steroids and esters as they relate to mathmatical and scientific theory. After that I will talk about some of the factors that speed up or slow down ester lifes and lastly I will jump into what I have experienced firsthand about me and how my body reacts.
I am not trying to insult anyones intellegence and am by no means an expert. I am just trying to be thorough. I just enjoy sharing what I learn and if you know something I dont please share and help me learn more.
1. Active Half Lifes of Steroids
The half-life may be defined as the time the level is half of the starting level of a given compound; at twice the time, the level is a quarter of the starting level, and at a third of the time, the level is an eighth of the starting level, and so on.
Here is a list-
Suspension within 1 hour
Acetate 1 day
Propionate 1 day
Phenylpropionate 1-2 days
Butyrate 2-3 days
Valerate 3 days
Hexanoate 3 days
Caproate 4-5 days
Isocaproate 4-5 days
Heptanoate 5-6 days
Enanthate 5-6 days
Octanoate 6-7 days
Cypionate 6-7 days
Nonanoate 7 days
Decanoate 7-8 days
Undeclenate 8-9 days
Undecanoate Approx 20 days
Let me elaborate on esters. Esters are what the steroid is attached to to make it last longer in your body to be absorbed. Can it be longer? Yes in some cases it is a day or two longer for longer ester AAS. There is alot of conflicting information on the internet but it really only deviates by 1-2 days.
So here is an example of a 10 week cycle of Test Cypionate 300mg/ml. It is injected on Monday every week at a dose of 2cc=600mg
Week 1 600mg/ Blood concentration of 600mg
Week 2 600mg/ Blood concentration of 900mg
Week 3 600mg/ Blood concentration of 1050mg
Week 4 600mg/ Blood concentration of 1125mg
Week 5 600mg/ Blood concentration of 1162.5mg
Week 6 600mg/ Blood concentration of 1181.5mg
Week 7 600mg/ Blood concentration of 1190.62mg
Week 8 600mg/ Blood concentration of 1195.31mg
Week 9 600mg/ Blood concentration of 1197.65mg
Week 10 600mg/ Blood concentration of 1198.82mg
Week 12 No Injection/ Blood concentration of 599.41mg
Week 13 No Injection/ Blood concentration of 299.7mg
Start PCT
That is basic beginner style cycle and you can see how about week 4-10 your blood concentration is pretty stable. Hence why people say it kicks in around week 4 and they use a kicker. This lag time of blood contentration building can be shortened by Backloading/preloading very high doseages in the first week or two.
Now lets see how it looks for a TRT patient in a 10 week blast then back to cruise. Our hypothetical roid monkey will be cruising on 300mg Test and just be doubling his doseage for his "blast"-
(This is assuming our roid monkey has been on TRT of 300mg 1x a week dose. Giving him a blood concentration of 580-610mg of test after the first 5 weeks of TRT)
Week 1 600mg/ Blood concentration of 600mg
Week 2 600mg/ Blood concentration of 900mg
Week 3 600mg/ Blood concentration of 1050mg
Week 4 600mg/ Blood concentration of 1125mg
Week 5 600mg/ Blood concentration of 1162.5mg
Week 6 600mg/ Blood concentration of 1181.5mg
Week 7 600mg/ Blood concentration of 1190.62mg
Week 8 600mg/ Blood concentration of 1195.31mg
Week 9 600mg/ Blood concentration of 1197.65mg
Week 10 600mg/ Blood concentration of 1198.82mg
Back to Cruise
Week 12 300mg/ Blood concentration of 899.41mg
Week 13 300mg/ Blood concentration of 749.70mg
Week 14 300mg/ Blood concentration of 674.85mg
Week 15 300mg/ Blood concentration of 637.42mg
Week 16 300mg/ Blood concentration of 618.71mg
As you can see around week 15ish is when blood levels are back to normal. So its a safe bet to say that after a 10 week blast of double a TRT dose you can be safe to get bloodwork around week 14-15 and that will be your "normal" blood level concentration. There are ways to speed this up like skipping a week dose, cutting your trt dose in half for a couple weeks and so on. It is kind of like the idea of "frontloading" high amounts of AAS in the start to get blood levels high except reverse. When you "backload" you cut doseage drastically to drop blood concentration to lower levels faster.
You can see how blood levels are very different between our TRT and Non-TRT users. So the same blood testing time does not necessarily apply to them both.
I have to get back to work and will add more to this later (lunch break is up lol).
