Post Cycle Therapy After Mast P Drostanolone: What You Need to Know

If you’ve been using the anabolic steroid drostanolone (Mast P), it’s crucial to follow it with an effective post cycle therapy (PCT) plan. Drostanolone, like other steroids, suppresses natural testosterone production. This can leave you feeling fatigued with low sex drive, reduced muscle mass, and other low testosterone symptoms.

A proper post cycle therapy helps kickstart your body’s natural testosterone production after a steroid cycle ends. It also helps you retain the muscle gains you achieved during the cycle. Here are some key medications to include in your PCT protocol after drostanolone.

Selective estrogen receptor modulators


Selective estrogen receptor modulators (SERMs) like Nolvadex (tamoxifen) are commonly used during PCT to block estrogen receptors in breast tissue. Estrogen levels can spike after ending testosterone-suppressing steroids like drostanolone.

Nolvadex will help prevent excess estrogen from triggering gynecomastia and other side effects. A typical Nolvadex PCT protocol is 20-40mg per day for 4-6 weeks following your drostanolone cycle.

Aromatase Inhibitors

Medications like Arimidex (anastrozole) inhibit the aromatase enzyme which converts testosterone to estrogen in your body. Keeping estrogen in check is important during post cycle therapy.

Arimidex is often stacked with Nolvadex at a dosage of 0.5-1mg daily for 4 weeks after finishing drostanolone. The combo helps restore hormonal balance.


Human chorionic gonadotropin (HCG) mimics the luteinizing hormone to stimulate testosterone production. Taking it before your SERM therapy helps kickstart your body’s natural testosterone production faster.

A typical HCG protocol is 250-500 IU daily for the first 2 weeks immediately after your last drostanolone injection. HCG primes your system for optimal recovery.

Liver Support

Since drostanolone is processed in the liver, adding liver protective supplements like milk thistle, NAC, and TUDCA can help support liver function during PCT. This aids in your overall recovery.

Talk to your doctor to craft the ideal PCT plan for your needs post-drostanolone cycle. Follow dosage guidelines closely to get your hormone levels back on track safely.
