Steroid Plotter Explanation

[Nelson Vergel]

SteroidPlotter is a leading online tool for planning and visualizing steroid cycles. It allows users to plot graphs and calculate levels for various anabolic steroids, TRT (Testosterone Replacement Therapy), and peptides based on dosage and half-life[1][2].

## Key Features

- **Graphing Capability**: Users can create visual representations of their steroid cycles, showing how compound levels change over time[2].
- **Customizable Cycles**: The tool supports cycles up to 100 weeks long for registered users[2].
- **Compound Library**: It includes a wide range of anabolic steroids, hormones, and other performance-enhancing drugs[5].
- **Dosing Schedules**: Users can set various dosing frequencies, from multiple times per day to every several weeks[5].
- **Comparison Feature**: The tool allows for comparing different compounds or cycles side by side[3].

## Additional Tools

SteroidPlotter also offers complementary calculators:

- **Testosterone Conversion Tool**: Converts between different units of testosterone measurement (e.g., nmol/l to ng/dl)[6].
- **Free Testosterone Calculator**: Calculates free and bioavailable testosterone levels based on total testosterone, albumin, and SHBG[10].

## Recent Updates

The developers regularly update the tool with new features and compounds. Recent additions include:

- New compounds like Boldenone Cypionate and Dihydroboldenone (DHB)[9].
- Improved pharmacokinetic models for more accurate blood level predictions[9].
- Additional dosing schedule options[9].

## Privacy and Security

SteroidPlotter emphasizes user privacy. While it allows for sharing protocols, users should be aware that shared information is accessible to anyone with the link[12].

SteroidPlotter serves as a valuable resource for those involved in or researching steroid use, providing a visual and mathematical approach to understanding compound levels over time. However, it's crucial to note that the tool should be used responsibly and in conjunction with professional medical advice.

How accurate are the graphs generated by the steroid plotter?

The accuracy of graphs generated by steroid plotters like SteroidPlotter.com is limited and should be considered approximate rather than precise. There are several factors that affect the accuracy:

## Limitations of the Model

- The plotter uses simplified pharmacokinetic models that do not fully capture the complexity of how steroids behave in the body[1][7].
- It assumes linear absorption and exponential decay based on average half-lives, which may not reflect individual variations[10].
- The model does not account for factors like metabolism differences, body composition, age, and genetic variances[1].

## Individual Variability

- Studies show vastly differing pharmacokinetics among individuals due to factors like metabolism and body composition[1].
- The calculated levels are estimates based on generalized information and cannot account for all individual differences[1].

## Recent Improvements

SteroidPlotter has made efforts to improve accuracy:

- They updated their pharmacokinetic model in 2024 to include more parameters like peak concentration and time to peak where available[7].
- A more advanced model was created for compounds where blood levels don't scale linearly with dosage[7].
- Users can now adjust levels up or down by a percentage to account for individual variation[7].

## Intended Use

The developers emphasize that the tool is meant to provide a rough idea of steroid levels over time, not precise numerical data[10]. It's designed to start conversations about optimizing cycles rather than provide exact blood level predictions[10].

While steroid plotters can be useful for visualizing and comparing different protocols, users should understand the limitations and not rely on them for precise dosing decisions. Consulting with a medical professional and basing treatment on individual symptoms and blood work remains crucial for safe and effective steroid use.

Can I customize the half-lives of each compound in the steroid plotter?

Currently, the steroid plotter does not allow users to customize the half-lives of individual compounds. The half-lives used in the plotter are based on established pharmacokinetic data and studies[11]. However, there have been some recent updates and improvements to the tool that provide more flexibility:

1. In October 2024, a new slider was added that allows users to adjust levels up or down by a specific percentage[5]. This feature is useful if you know you respond differently to a particular compound, as it lets you account for individual variation.

2. The developers have implemented a more advanced pharmacokinetic model for some compounds where blood levels don't scale linearly with dosage[5]. This model includes parameters like peak concentration and time to peak, which can provide more accurate results for certain steroids.

3. The plotter now uses a linear regression equation for some compounds to better mimic the diminishing effect seen as doses increase[5].

While these updates improve the accuracy and flexibility of the tool, they do not allow direct customization of half-lives. The developers seem to prioritize using scientifically established data rather than allowing user-defined values, likely to maintain the tool's reliability and consistency across users.

If you need to account for specific variations or have data suggesting different half-lives, you might consider using the percentage adjustment feature or comparing your results with real-world experiences and blood work.
