It depends on which SARMs you use, the dosage, and the cycle length. Some SARMs are mild and cause little to no suppression, while others suppress natural testosterone production significantly, requiring PCT.
When Do You Need PCT?
✔ Strongly Recommended PCT: For SARMs that are highly suppressive:
• RAD-140 (Testolone)
• S23
• YK-11
• LGD-4033 (Ligandrol)
✔ Mild Suppression (Maybe PCT):
• Ostarine (MK-2866) – Low doses may not require PCT
• Andarine (S4) – Mild suppression at moderate doses
✔ Least Likely to Require PCT:
• Cardarine (GW-501516) – Not a SARM, no suppression
• MK-677 (Ibutamoren) – Growth hormone booster, no suppression
What Happens If You Skip PCT?
If you run a highly suppressive SARM and don’t use PCT, you may experience:
⚠ Low energy & fatigue
⚠ Loss of muscle gains
⚠ Decreased libido & mood swings
⚠ Longer recovery time for natural testosterone
Best PCT Options:
• Nolvadex (Tamoxifen) – Mild PCT
• Clomid (Clomiphene) – Stronger PCT for heavy suppression
• Natural Test Boosters – Help support recovery but may not be enough alone
Final Answer?
If you’re running a powerful SARM, always be prepared for PCT! If using a mild SARM at low doses, you might recover naturally.
