Welcome to CompoundLab.

Your Starting Point

CompoundLab works best when you start with the reason you opened it.

Most users arrive with one of four questions:

• “I heard about a compound. What does it actually do?”
• “I am thinking about TRT. Where do I start?”
• “I am considering a first cycle. What would make that a bad idea?”
• “I already use PEDs. How do I catch weak spots in a plan?”

Pick the closest path below. You can always come back and branch into the others.

If You Are New to PEDs

Start with the Foundation track before you touch the Cycle Builder.

Read these first:

1. Harm Reduction for PED Users
2. Bloodwork Basics for PED Users
3. Hormones, the HPTA, and Suppression

Those three lessons give you the vocabulary for the rest of the site: suppression, estradiol, hematocrit, liver markers, lipids, recovery, and when a plan crosses from manageable to reckless.

After that, open one compound page you are curious about and read it like a risk profile:

• What problem is this compound usually used to solve?
• What side effects show up because of its mechanism?
• What bloodwork would catch trouble early?
• What simpler option does it compete with?

Compound pages are strongest when they slow down a rushed decision.

If You Are Thinking About TRT

Use the TRT track when your actual question is medical replacement therapy.

Start with Low Testosterone, TRT, and Diagnosis, then follow the TRT track outline. The outline and the next-lesson links use the same sequence, from diagnosis and alternatives through protocols and monitoring.

The goal is better questions for a clinician: symptoms, repeat labs, LH/FSH context, fertility plans, hematocrit, estradiol, and the difference between replacement and enhancement.

If You Are Considering a First Cycle

The first useful question is whether the plan should exist.

Begin with Before Your First Cycle, then follow the Beginner Anabolics track. It covers readiness, planning, side effects, and off-ramps in that order.

Then use the Cycle Builder to model the simplest version of the plan. Let the warnings point you toward better questions:

• What is the main risk driver?
• What would need monitoring?
• What happens if estrogen, blood pressure, hematocrit, or lipids move the wrong way?
• Is every added compound earning its place?

The builder is best used to simplify plans and expose blind spots.

If You Are New to Peptides

Peptides have their own track because the problems are different: vial math, sterility, storage, counterfeit risk, and confusing category boundaries.

Begin with Intro to Peptides, then follow the Peptides track outline. Preparation and syringe math come before the compound-specific groups. Use those groups to find your area of interest.

Use the Peptide Dose Calculator after you understand the vial math. A calculator confirms arithmetic. Product quality, protocol fit, and dose appropriateness still require judgment.

If You Are Comparing Compounds

Use Browse when you are still orienting by category. Use search when you already know the compound name.

Browse helps with questions like:

• Which compounds are oral, injectable, ancillary, peptide, or metabolic?
• Which options are beginner-facing versus advanced-only?
• Which compounds aromatize, affect prolactin, stress lipids, or carry liver risk?
• Which lessons should be read before a compound gets added to a plan?

Search is better for a specific target like Testosterone Cypionate, BPC-157, Primo, or Semaglutide.

If You Already Have Experience

Advanced users usually need better filters more than more enthusiasm.

Use these areas:

• How Steroid Families Behave, for structural families and mechanism
• Stack Design: Logic, Synergies, and the Principle of Least Complexity, for deciding whether a stack is coherent
• Reading Labs While On Cycle, for interpreting bloodwork under active compound exposure
• Long-Term Health Management for PED Users, for cardiovascular, kidney, liver, and organ-risk thinking

Advanced content should make your filters sharper. If a stack looks clever but cannot be monitored cleanly, that is a design problem.

Your First Session

Here is the fastest useful walkthrough:

1. If you are new, finish Foundation. Then pick a track for your question.
2. Read the first lesson in that path.
3. Open one related compound page.
4. Use Browse to compare alternatives.
5. If a full protocol is involved, model the simplest version in the Cycle Builder.
6. Follow the warnings back into the relevant lesson.

That loop is the point of CompoundLab: learn the concept, inspect the compound, test the plan, then go back and fill the gap.

Reviewing a Plan

Good use of CompoundLab means you can explain:

• why each compound is present
• what each compound adds
• which risks overlap
• what labs or symptoms would change the decision
• what the off-ramp is if the plan starts going badly

If a page, warning, or lesson makes you less excited about a first draft, that is useful. A cleaner plan is usually more valuable than a more complicated one.
