Andro Guide: Which Andro is Right For You?

The Ultimate Guide to Prohormone Cycles

Your roadmap to safe and effective cycles.

IMPORTANT DISCLAIMER

This guide is for informational purposes only and does not constitute medical advice. The information provided is intended for an audience of healthy, adult males over the age of 21 with significant weightlifting experience. Prohormones are powerful compounds that can have significant effects on your hormones and overall health. They can cause serious side effects if not used responsibly. Always consult with a qualified healthcare professional before beginning any new supplement regimen, especially one involving hormonal compounds. Get bloodwork done before and after your cycle to monitor your health markers. You are responsible for understanding the laws in your country regarding these compounds. Use at your own risk.

1. What Are Prohormones?

Welcome to the definitive guide on prohormone usage. As a dedicated bodybuilder, you're always looking for a safe and effective edge to push past plateaus and achieve your physique goals. This guide is designed to educate you on how to approach prohormone cycles with intelligence and a focus on long-term health.

Prohormones are chemical compounds that are precursors to anabolic hormones like testosterone. Think of them as the raw materials your body can convert into active hormones.

How Do They Work?

Once ingested, prohormones are converted by enzymes in your body into active anabolic hormones. This increase in hormones is what leads to the desired effects for bodybuilders:

  • Enhanced protein synthesis for faster muscle growth.
  • Increased strength and power output.
  • Improved recovery between training sessions.
  • Greater nitrogen retention, creating an optimal environment for muscle building.

2. Prohormone Profiles: Choosing Your Compound

1-Andro Prohormone

1-Andro (1-Androsterone / 1-DHEA)

Primary Goal: Lean Muscle & Strength

1-Andro is one of the most popular prohormones because it delivers clean, high-quality muscle gains with low water retention. It converts to 1-Testosterone, a powerful anabolic compound. Our top seller is Blackstone Labs Chosen1.

  • Significant increases in lean muscle mass
  • Noticeable strength gains
  • Does not convert to estrogen

4-Andro Prohormone

4-Andro (4-Androsterone / 4-DHEA)

Primary Goal: Bulking, Mass & Power

4-Andro is the king when it comes to packing on raw size and strength. It converts directly to Testosterone, the primary male androgen. The top seller for an 4-andro is Hi-Tech Pharmaceuticals Sustanon 250.

Epiandrosterone Prohormone

Epiandrosterone

Primary Goal: Cutting, Hardness & Fat Loss

Epiandrosterone is the go-to compound for cutting cycles. It is a precursor to Stanolone (DHT), known for its muscle-hardening and fat-mobilizing effects. If you are looking for an epi-andro, then Winstrol by Hi-Tech Pharmaceuticals is what our customers purchase the most.

  • Excellent for recovery
  • Soothes joints

3. The Three Pillars of a Safe Cycle

Pillar 1: On-Cycle Support

The "Protection" Phase. Taken during your cycle to protect organs and manage side effects like liver stress and high blood pressure. **DO NOT SKIP THIS.** Blackstone Labs Gear Support is our most popular on-cycle support supplement.

Pillar 2: Post-Cycle Therapy

The "Recovery" Phase. Taken after your cycle to restart your natural testosterone production and solidify gains. THIS IS MANDATORY. Arimiplex by Hi-Tech Pharmaceuticals is our most popular PCT.

Pillar 3: Cycle & Time Off

Cycles last 4-8 weeks. Your "time off" should be at least your cycle length + PCT length combined. (e.g., 4wk cycle + 4wk PCT = 8wks Off).

4. Final Checklist for Success

  1. Are you over 21? If not, do not use prohormones.
  2. Have you been training consistently for at least 2+ years?
  3. Is your diet and training dialed in? Supplements don't work in a vacuum.
  4. Do you have all three products? (Prohormone, On-Cycle Support, and PCT).
  5. Have you consulted a doctor and had bloodwork done?
  6. Are you committed to the full cycle and recovery period?
