NOTE: We aim to make our calculator as useful as possible based on publicly available studies and data. However, there are significant limitations, assumptions are made, and a simplified pharmacokinetic model is used. The half-lives and pharmacokinetic variables used are estimates and will differ between individuals. This tool is for entertainment only and should not be used to make medical decisions. Always consult a healthcare professional before altering any medication regimen. This calculator and its content are not medical advice. Use at your own risk.
Notes:
- Where possible, we obtain the elimination half-life (t1/2), peak concentration (Cmax), time to peak (Tmax), and bioavailability (F(%)) of included compounds from peer-reviewed scientific studies.
- Sometimes, certain pharmacokinetic values are less easy to ascertain. In these cases, we have to make assumptions to estimate these values, which will not accurately reflect the behavior of these compounds in real-world scenarios.
- Pharmacokinetic data and studies/sources used for compounds used in the plotter application are included below.
- Please visit our FAQs page for the most frequently asked questions we receive about the SteroidPlotter website & application.
Pharmacokinetics & Sources:
We are currently maintaining a Google Sheet listing current pharmacokinetics and sources. This sheet is a work in progress and will be ported to the website once completed.
If you have any feedback or suggestions or want to see a new compound added, please do not hesitate to contact us in our Telegram group.
This is an amazing tool. Thank you!
Thank you for your support!
Something is off. 17mg of test prop a day and 40mg of test cyp 3x/wk result in extremely different profiles. Even being around the same relative dose of 120mg. I expect slight variation in the test p being higher but not by that much….
Same here. Test Prop looks like its over concentrated or something is wrong with this test profile.
mg for mg test p has more test than cypionate. test p is ~80% test, test c is ~67%. so you’re getting about 1.2x the amount of test with test p as you are with cyp at the same dose of the compounds.
i just checked them adjusted to compensate for the differing molecular weights of the ester chains and cyp peaked at ~720 and prop at ~750, so pretty close (at 120mg cyp to 100mg prop, ~80mg/week of actual test each)
double posting to add a little bit and fix grammar, just delete the other please. and hey thanks for the all hard work you put into the site, much appreciated
This is likely down to the levels seen in the studies used for each compounds rather than something you’d necessarily see on an individual basis. In the future we may end up moving to more normalized pharmacokinetic data so that things match up more accurately for different esters as it seems to cause some confusion.
Do you add your starting test number to the number in the chart to get where your total should be?
No, the chart assumes your natural production is shut down.
I feel like the mg of hormone for Test U is off,
it was different in the last UI you had.
Can you explain what you mean exactly (mg is off)?
You can still access the old version of the site here: https://old.steroidplotter.com/
Sorry, I meant the active hormone of the drug seems off.
200mg of test U weekly shouldn’t result in higher levels than 200mg of test c weekly.
Is it possible to view the days beyond the administration (intake) of drugs, in order to observe how long it takes to completely eliminate (full decay)? Thank you!
Yes, simply increase the cycle length past your last dosage to see the decay.
when touching the “downloading to xls” the “share this protocol” tab is in front of the “Download xls” touch tab, so it’s difficult touch one or the other
Can you add a change units options to nmol? Thanks
Hi, unfortunately this is not a simple task due to the multiplier for each compound varying based on molecular weight but we will add to the backlog.
In the mean time, you can convert testosterone between these units here: https://steroidplotter.com/testosterone-conversion-tool
Many thanks !
Would really appreciate an option to toggle date with simply week 1, 2 etc
Can you explain in a little more detail what you are after? e.g. Start date/cycle length/x-axis on the chart. Thanks.
Really just week 1 to week 12 for example
You see I consider things in terms of the number of weeks into the cycle. so it’s more useful for me to see that at ‘week 4’ I’ll be at maximum blood levels
Start date would simply read Week 0
Horizontal axis would by weeks 1 through 12 for example
Thank you
Got it. Will add to backlog.
Hello, Would it be possible to increase the cursor up to 120%
Because with 120 per week divided into 60 twice a week
I reach 1695 testosterone and with the cursor at 100% I reach 1500
Have added this to the backlog.
