====== Liver Protection (TUDCA, Milk Thistle) ======

Many anabolic steroids—especially 17α-alkylated oral compounds—pose a risk to liver health. To mitigate hepatotoxicity, bodybuilders often use liver support supplements. Two of the most commonly used compounds are:

  * **TUDCA** (Tauroursodeoxycholic acid)
  * **Milk Thistle** (Silymarin)

Other compounds such as NAC and Liv.52 are also used, but this entry focuses on the most widely recommended options.

===== Why Is Liver Protection Necessary? =====

**Oral anabolic steroids** like Superdrol, Winstrol, Anadrol, and Dianabol are modified at the C-17α position to survive first-pass liver metabolism. This increases bioavailability but places heavy stress on the liver.

Signs of liver stress may include:

  * Elevated **ALT** and **AST** (liver enzymes)
  * Fatigue
  * Nausea or digestive discomfort
  * Jaundice (in extreme cases)

Bloodwork is the only reliable way to assess hepatotoxicity. Monitoring **ALT, AST, GGT, and bilirubin** is strongly advised during and after oral cycles.

===== TUDCA: The Gold Standard =====

**TUDCA** (Tauroursodeoxycholic acid) is a bile acid that protects liver cells by reducing endoplasmic reticulum (ER) stress and promoting bile flow.

Benefits:

  * Clinically proven to treat cholestasis
  * Reduces liver enzyme elevation
  * Protects hepatocyte membranes
  * Non-toxic and well-tolerated

^ Compound ^ Recommended Dose ^ Timing ^ Notes ^
| TUDCA | 250–1,000 mg daily | On-cycle (especially with orals) | Best taken with food for absorption |

User anecdotes and clinical evidence suggest TUDCA is the most effective liver protection compound available for steroid users.

===== Milk Thistle: Traditional Support =====

**Milk Thistle** (active ingredient: **silymarin**) is a herbal antioxidant that protects the liver by scavenging free radicals and stabilizing liver cell membranes.

Benefits:

  * Antioxidant and anti-inflammatory properties
  * May aid liver regeneration
  * Mild protective effect on liver enzymes

Limitations:

  * Poor oral bioavailability
  * Evidence for use in **preventing** steroid-induced hepatotoxicity is weak
  * More useful for **general liver health** than high-stress oral cycles

^ Compound ^ Recommended Dose ^ Timing ^ Notes ^
| Milk Thistle (Silymarin) | 300–600 mg daily | Off-cycle or as background support | Better as preventive/tonic support, not standalone for oral cycles |

===== Other Common Liver Support Compounds =====

  * **NAC (N-acetylcysteine)** – Glutathione precursor; antioxidant support
  * **Liv.52** – Ayurvedic blend; anecdotally popular but clinically weak
  * **UDCA** – The prescription counterpart to TUDCA, similar effect
  * **Choline & Inositol** – Old-school support, low efficacy

===== When to Use Liver Support =====

^ Situation ^ Recommendation ^
| **Running oral AAS** | Use **TUDCA daily** during the cycle |
| **Post-cycle or TRT** | Optional Milk Thistle or NAC |
| **Injectables only** | Liver support not typically required, but NAC is optional |
| **High liver enzymes on bloodwork** | TUDCA strongly advised; discontinue orals immediately |

Note:

  * Using multiple liver supports (e.g., TUDCA + NAC) is common, especially with harsh orals
  * Even “milder” orals like Anavar and Turinabol can elevate liver enzymes

===== Bodybuilder Advice (from r/steroids PDF) =====

  * “TUDCA saved my labs during a Superdrol run—AST/ALT were triple before, then normalized.”
  * “Milk thistle is fine for general use but useless for Superdrol or Halo.”
  * “NAC and TUDCA is the best combo I’ve used—never saw enzymes above range.”
  * “If your orals are working, your liver is hurting. Period.”

===== Summary =====

  * **TUDCA** is the most effective liver protection for oral steroid users
  * **Milk Thistle** has general liver support benefits but lacks potency
  * Use TUDCA **on-cycle**, especially with methylated oral AAS
  * Monitor liver enzymes with bloodwork regularly
  * Stack with **NAC** for enhanced antioxidant support

Protecting liver health is essential for anyone using oral AAS. Failure to do so can result in serious medical complications and long-term damage.
