How long for testosterone cypionate to fully leave your blood and have body levels drop?

Do you get any results from two months of prop? I'd think an oral cycle would be the only one that short that might have good yields.

Well yes, I would definitely think you could get some results. I'm no ifbb pro, but in my experience even with some longer esters when I push the weights and food hard by about two months in I'm getting drained. The weights have gone up a lot for 8 weeks. Some good added size too, but I feel so beat I'd swear it was 12 weeks. But I was just pushing hard as I could. That's on maybe test e, NPP and mast prop. So even with one medium water I def still noticed it. I'd think with test prop be very much the same. ( So the medium water doesn't mess up your bw) My experience.
 
Half life is 10.5 days so.....

650/2= 325
325/2= 162.5
162.5/2= 81.25 this half life you want at 10.5 days /2= 5.25 to give you 122mg approximately

Total is 10.5 + 10.5 + 6 days or 27 days

I use my own calculations for almost a decade now and my bloods come back as expected so as not to upset the apple cart with my doc.

Crappy part with cyp is that this process is a crash so I do get lethargy and such on the way down. If I had the time I switch to prop and use a 4.5 day half life. The benefit to this is a healthy bump at the end of the cycle when the cyp is going out and prop is going in.

Dam so if your doc requested bloodwork every 3 months you'd literally have no time to blast. Shit I may have painted myself into a corner with this lol.

Correct and had to not blast for just over a year before my doc felt comfortable to go to yearly tests. Don't worry he will relax the tests after a while, I have never heard of anyone I know doing every 3mths for years (so far). Play by the rules and you get a lifetime of HG test :)

No blasting during the every three months for me because, like others said, elevated results for things like estrogen. Estrogen is produced from the decomposition of test in the body so estrogen lags test. To remove is to use an anti estrogen (I prefer a suicide to remove the estrogen not arimidex to bind and block). To keep playing and playing with things I will eventually screw things up so again just play by the TRT rules and if I were you self reduce to 120mg/wk max so as to hit the middle of the range which is where the doc wants most to be. Also I test always at about the 6 day mark after injection. If test at 3 days the levels are too high. Timing is everything. Myself I use 100mg when I my script says something else and I am at 350 after 6 days.

Orals will severely screw up the results for other aspect of the bloods like enzymes. Please don't because it is difficult to explain. Almost impossible to explain away actually because the doc would and should raise press the alarm bell on the wacked out results.

Maybe I'll play it safe. I believe i may be the first person my doc has ever given trt too I think he said he is only going to check cbc and serum testosterone no estrogen or anything else but maybe doen the road I'll ask him to add in some other good markers. I was thinking about popping dbols while I wait it out for the 29 days good thing you mentioned not to lol.
 
Did he give you the requisition yet? If so what boxes are checked and what do you see on the side where the additional test note are?

At 650/wk at 29 days you will be swimming in estrogen again because it lags test and the body has not had enough time to convert it out. If you can wait it out an additional month (two months total) you will stand a much better chance of the explanation "could be" that you are an estrogen producer since it will still be pretty high. He might even order another test a month or two later as doc's are truly concerned about your health and their license. After 27 days start 100mg/wk and take the test 6 days after last injection at the 2mth mark and all should be pretty good but again estrogen will be a tough inflated over a true TRT reading

This might help....

Would that 23 days be back to hypogonadal stage or still in trt range?

I included the link to the chart to demonstrate, 23 days from last injection to the beginning of his desired range. A few days more to reach the bottom. Of course the plotter is for informational purposes only, but good to consider when your script is on the line..
 
I love chatgbt lol

Goal:

Estimate when your serum testosterone levels will resemble someone injecting 125mg/week.

That means your levels need to drop to:
125 / 650 = ~19.2% of your steady-state levels.


---

How many half-lives to reach ~19%?

We use this formula:
Remaining % = (1/2)^(days ÷ half-life)

Rewriting to find days:
days = half-life × log2(starting dose / target dose)
= 8 × log2(650 / 125)
= 8 × log2(5.2)
= 8 × ~2.37
≈ 19 days


---

Result:

It will take ~19 days after your last 650mg/week dose for your serum testosterone levels to fall to match someone taking 125mg/week.

But what about the people that take 125mg/ week and end up with 1000 ng/dl + levels? I suppose they'd have to do the math for a lower target dose?

I won't do this as I screwed up a test one time going in 62hrs after injection getting an 850 result from 125mg dosage (continuous 125mg/wk dosage so I am saturated), if someone took 125mg and took the test 36hrs later they could be over the 1000 mark. Same dosage taking the test at 6 days I was over 500 which was when my doc cut me back to 100mg/wk to hit the middle of the range. It's my responsibility to ensure I get into the middle of the range so I don't get any changes.

I see that AI calculation uses 8 days for a half life. No idea why that number was used. Guess another problem of AI and not validating answers. I never blindly believe everything I see especially on the net

For anyone interested 500mg test cypionate and exactly 4 weeks to the day from my last shot and my bloodwork was 8.4 nmol/L. Its not perfect because my test dose was up and down through out the cycle but the last few weeks it was steady at 500mg.
 
Which is the lowest point of the normal range, one decimal lower it would have been flagged as low.

Out of curiosity, did you get prescribed TRT with those levels?
Click to expand...
No i went in to a trt clinic and actually had higher levels and got perscribed. These standards the 8.4 was done through my gp but he is now prescribing me test based on the fact I've already had it for so long. I don't know for sure but GPs maybe want to see it even lower. The ones who aren't used to prescribing it anyway.
 
Did not read all the replies but no one can really tell you for certain. The first thing I did with Test E and Test P was do a mild cycle - nothing near your dosage but stop and paid for my own blood tests to determine when I am in normal range, at the bottom to determine if I am on TRT, how do I guarantee my Total Test will be where I expect. It wasn't cheap as I had to do multiple tests, but pending the testosterone was properly dosed - I knew exactly how many days, pending no health changes, where I would be after a specific number of days.

I may be way higher than you at 19 days because my liver/kidneys/system in general doesn't work as well or we are just physiologically different.
I hate to be a broken record but pay for your own tests if you want script TRT and want to dabble.
These tests showed total T being down into a normal level/below level, but any knowledgeable doctor who does more than total and free test will know I gamed the system. Sure, there are ways to discuss this with your doctor and easy answers to give (if you want to discuss them, send me a PM), but chances are they will be skeptical. When I had low test and given TRT by my GP - it was not from steroid abuse. No real explanation - not only did I never abuse steroids - (yes, I did small 8 week pyramid cycles of max 400-500 mg for one week at the peak) - once a year for a few years. I was off for 5 years when I asked my doctor to test it. My total test was well below normal parameters and he prescribed.

Your on TRT do many of those hormones are going to be low anyway which is good but if you want to be sure, pay for the private tests. Alternatively, be ready to answer questions if the doctor asks them.
I see this is a bit of an old thread - how did it all end? Sorry in a rush and didn't read every post.

Thanks

Thanks for your thoughts. Exactly 4 weeks to the day of my last shot of testosterone enanthate at 500mg a week and my serum testosterone was 8.4 nmol/L. That according to the labs reference ranges was the very bottom end of normal.

I would have to say you are pretty well bang on with this am getting ready for blood work to get on trt it’s been 29 days since my last shot of test c this is the longest I’ve went with no test in years and I feel exactly like 10 lbs of shit in a 5 lb bag !!! I don’t even feel like the same person I’ve lost 7 lbs and it’s a huge effort to train a hour a day!
