Start Here: How to Use CompoundLab
A practical first-session guide for choosing the right track, using compound pages without treating them like shopping pages, and turning Cycle Builder warnings into better decisions.
- Choose the right starting path based on whether you are peptide-curious, TRT-curious, first-cycle curious, or already experienced
- Use compound pages as risk profiles instead of shopping pages
- Use the Cycle Builder to simplify plans and identify weak points
- Know which lesson or tool to open first for common user goals
- Treat warnings, monitoring needs, and off-ramps as part of the decision rather than cleanup after the fact
Start With Your Actual Goal

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:
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 here:
- Low Testosterone, TRT, and Diagnosis
- Clomiphene, Enclomiphene, HCG, and TRT Alternatives
- TRT Protocols: Dosing, Frequency, and Delivery Methods
- Bloodwork and Monitoring on TRT
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.
Start here:
- Before Your First Cycle
- The First Cycle: Testosterone Only
- Estrogen Management for Beginners
- On-Cycle Bloodwork and Health Monitoring
- How PCT Works
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.
Start here:
- Intro to Peptides
- Peptide Reconstitution and Injection Math
- Healing and Recovery Peptides: BPC-157 and TB-500 or GLP-1 Receptor Agonists: Semaglutide, Tirzepatide, and Retatrutide, depending on your goal
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.
A Good First Session
Here is the fastest useful walkthrough:
- Pick your path: TRT, first cycle, peptides, or advanced review.
- Read the first lesson in that path.
- Open one related compound page.
- Use Browse to compare alternatives.
- If a full protocol is involved, model the simplest version in the Cycle Builder.
- 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.
The Standard to Aim For
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.
