Math question about test and blood levels

[New-Jedi]

____
The longer you wait after the pin, the lower the value. If you are dividing up the dose to twice per week, the likelihood is about 1,000 ng/dL might be the low point. Again, if you are trying to see the UG dosing accuracy, IMO the peak is the best, albeit indirect, gauge. Use the entire dose and do not split. [A common problem is many labs will only provide a report >1,500 ng/dL.]

On another point, who/why would anyone cycle at 200-250! Unless, this is combined with another AAS.

Do you mean cycle at 250mg a week, or twice a week! I am about to start my first cycle of test e, 500mg a week. Do you think I should do the whole 500mg in one pin instead of two every three and a half days?

No he's not saying cycle at 250mg, unless it's combined with another AAS. If you plan on guaging the dosage of your testosterone, the best method would be to pin once a week.

This is what's called a dynamical system. You have an initial value M0 , the value of a future state or "generation" Mn+1 , and we look at the rate of change in between generations by looking at constants r and d. In this case r is 1- the % of testosterone cleared by the body in n our chosen time period, and d is the amount of drug introduced in each generation. This gives us the equation

Mn+1 = r*Mn + d

So in this case we can say n the generation is anything really but it would be easiest to set it to the length of the drug's halflife, rather than your dosage interval so that we don't have to get into how much of the drug has been cleared in that time as its not necessarily linear. So to sub in our values, our starting dose M0 is 0, r is 0.5, and d is going to be the halflife in days/7 * 750. The halflife of test enanthate is the tough part because its actually pretty variable, but if we choose to set it at 10 days that gives us a value of 1071.4mg per generation. Now to find the equilibria of the system we make Mn+1 and M0 now the value M and solve for M. Giving us:

M = r*M + d

Note that r is not to the power n as we are not looking at a number of future generations. So if we solve for M we get simply get M = 2(1071.4mg) = 2142.85mg of test remaining in the body in each subsequent generation. You can check this by plugging in this value for M0 in the original equation.

The whole problem with this is that its a very idealized system. The half length of testosterone is dependent on the person and the amount of SHBG and enzymes like aromatase so the system becomes more complex because we need to change the value of r to an expression containing a value for epsilon, modifier(s) that takes into account these variables.

The more and more I read the more and more I feel my gear is about spot on. I've read numerous Watson Cyp threads, where 200mg was adminstered through two weekly pins. Bloods were four days after pin and levels are between 1000-1100 ng per dl. Been also reading the SHBG plays a big role. I did note now Watson cyp thread saying 250mg put him at 2500 ng per dl. But that doesn't seem to be anywhere near common??

For what it's worth, I have a prescription and get test cyp from pharmacy. I take 100mg/w, and blood work every 3 months. sometimes my levels are 12 or 1300 and my doctor gives me shit about it. She's cool with 800, so I have to back off before I go in for visits. I've been led to believe olympic athletes test level is around 800.

 

[Str8Shooter]

1000 sounds about right since he is splitting 200mg into 2 100mg doses per week right?

for what it's worth, I'm prescribed 100mg/week, bloodwork every three months, levels usually around 1200. Doctor didn't like that, so I have to back way off before I go in.

This is utter bullshit. At 100mg Watson I'm at just about 500 test and 200 just over 700. Where are u guys pulling numbers from

At 140mg of my pharm trt, I'm at 700. Bloods pulled 7 days after my pin.

 

[Just Fish]

D-max labs came back inconclusive for too much semen. Guess that's what happens when you suck too much cock. Love how you posted your boyfriend in your avatar pic. Lol, pussy

Thought this mighr have a good place here in this thread.........


250mg of test a week- T level should be 1100-1600ng/dl
500mg of test a week- T level should be 1800-2500ng/dl
750mg of test a week- levels should be well into the 3000's

According to an official clinical application :

25mg of test a week- T level was 253ng/dl
50mg of test a week- T level was 306ng/dl
125mg of test a week- T level was 542ng/dl
300mg of test a week- T level was 1,345ng/dl
600mg of test a week- lT level was 2,370

 

[Maneuvers]

My last cycle containing 500mg/wk test e resulted in 3,681 total

 

[EcpertRealistic]

If you're doing 750/week of test E, how do you calculate how much test you should have via blood test, once you reach steady state levels?

what should the blood test results show, so that you know your shit isn't underdosed?

(I know it fluctuates, but a ballpark figure would be good.)

It depends on your blood volume hydration levels etc. Someone that is 6'6" tall will show a lower amount of free testosterone at a certain dosage than a 5'5" guy. Weight and muscle mass also can play a role.

On average a 5'10" guy can expect approximately around 700+ng/dl for every 100mgs of test/week. Shorter guys can see lab results up to 850ng/dl from every 100mgs of test.

Some test forms like propionate have a higher bioavailability and may show SLIGHTLY higher concentrations of test in blood than others longer ester based testosterones on a mg by mg basis.

I red all pages and just found 3 good postings...
Nobody wrote of they are using pharma grade stuff or ugl gear.
Time of pinning and date of drawing bloods ist mostly not told. It is useless to discuss about that without these information.

Don't forget 250 mg/ml of test E contains the ester weight as well. Just 180mg of active testosterone is in 1ml of that label claim.

The graph is from an official pharma company in Germany. Baseline is naturally produced testosterone of 4ng/ml.. you have to substract that.. so with accumulation effects and pinning e7d you will not surpass 15ng/ml After 24 till 48h post injection when your natural production ist shut down..
Last year after 24h of injection I had 1536ng/ml.
Last week after 6 day of last injection I just had 469ng/ml.. pinning 250mg/ml test E a week.
Pharma Grade from jenapharm out of a German pharmacy.
Next week I will redo testing but with the same time between pinning and drawing bloods as last year to do the double check.

Holy shit, this changes everything. I'll have to adjust my dosages. Deca only has 62mg active hormone per 100mg!!!

 

[Klimmzugernie]

Not sure if you're are serious... But it is important to correct the expectations of some users about their bloods based on dosages they use. Not every one is aware of that

 

[G2Ready]

what factors would influence a variance in these levels from person to person?
aromatisation?
injection location?
SHBG?
ester of the test injected?
how bout the method of testing> roch vs. ms

Sorry to quote ya from 2014

But was curious if this was ever answered..

If typically people see x10... and most get x7.5

Why do some (like myself) receive WAY BELOW the 10x rule????

 

[G2Ready]

My GUESS was aromatisation

But I’ve recently started reading on PDE7B gene...
^^^what I’ve read so far is above my pay grade as meat head

After 10 injections (end of week 5) of T400** at 500mg a week, I did bloodwork.
It was done 36 hours after last injection.

Estradiol - 56 (I didn't do AI the first 5 weeks. Wanted to get labs without first)
Test - 1900: didn't expect it to be this low. Thinking my gear is underdosed?

**(100mg P, 150mg C, 150mg E)

 

[Klimmzugernie]

Don't get it. t400 is 100mg p, 150 c and 150e? How do you come to 500mg??

 

[Sajan]

Don't get it. t400 is 100mg p, 150 c and 150e? How do you come to 500mg??

I just inject roughly 1.25mL a week (split into 2 doses).
Most people inject 2mL since their gear concentration is 250mg/mL.

 

[Klimmzugernie]

OK. After 36 hours the P is mostly away. And c and e haven't hit their maximum ..
Invasion half time is different depending on oil etc.. I would think 1900-2200 is not so bad. By injecting ~0.65ml twice a week your result of 1900 Ng/ml is pretty good

Bro sience say glute injection cause higher blood levels...

Anyway ... Just for your reference.. after 36 hours of pharmacy test E 250mg/l my blood levels are at 1300...after 6 days at 500ng/ml
