Description
Tamoxifen 20mg x 60 Tabs
Tamoxifen 20mg x 60 Tabs is a selective estrogen receptor modulator (SERM) widely prescribed for breast cancer prevention and treatment. It is also utilized in post-cycle therapy (PCT) by athletes and bodybuilders to restore natural testosterone production after anabolic steroid use.
Classification of Tamoxifen 20mg x 60 Tabs
Tamoxifen belongs to the SERM class, meaning it can act as an estrogen antagonist in certain tissues (like breast tissue) and as a partial agonist in others (such as bone or endometrium).
Pharmacological classification: Antineoplastic agent, Hormone modulator.
What Is Tamoxifen 20mg x 60 Tabs?
Each tablet contains 20 milligrams of Tamoxifen citrate, the active compound responsible for blocking estrogen receptors. The pack of 60 tablets provides a 30–60 day supply, depending on prescribed dosage.
Common brand names: Nolvadex, Soltamox.
Pharmacological Profile and Drug Class
- Drug Type: Nonsteroidal anti-estrogen
- Form: Oral tablet
- Active Ingredient: Tamoxifen citrate
- Therapeutic Class: SERM
- Target: Estrogen receptor (ERα, ERβ)
Recommended Dosage for Tamoxifen 20mg x 60 Tabs
For breast cancer treatment, the usual adult dose is 20–40 mg per day, taken orally.
For post-cycle therapy, athletes often use 10–20 mg daily for 4–6 weeks.
Important: Only take Tamoxifen under medical supervision or after consulting a qualified healthcare provider.
How Does Tamoxifen 20mg x 60 Tabs Work?
Tamoxifen functions by binding to estrogen receptors, blocking the hormone estrogen from stimulating the growth of estrogen-dependent cancer cells.
In men, it helps restore natural testosterone production by reducing estrogen’s inhibitory effect on the hypothalamic-pituitary-gonadal axis.
Mechanism of Action Explained
Tamoxifen acts as an estrogen receptor antagonist in breast tissue. It prevents estrogen from binding to the receptor, inhibiting cancer cell proliferation.
However, in other tissues such as the bones, it acts as a partial agonist, helping maintain bone density in postmenopausal women.
Uses of Tamoxifen 20mg x 60 Tabs
- Treatment of estrogen receptor-positive (ER+) breast cancer
- Prevention of breast cancer in high-risk women
- Post-cycle therapy (PCT) in bodybuilding
- Gynecomastia prevention in men using anabolic steroids
Tamoxifen in Breast Cancer Treatment
Tamoxifen is a cornerstone in adjuvant therapy for ER-positive breast cancer.
Clinical trials show it reduces the risk of recurrence by up to 40% when used for 5 years after surgery
Tamoxifen in Post-Cycle Therapy (PCT)
After steroid cycles, natural testosterone levels drop. Tamoxifen stimulates LH (luteinizing hormone) and FSH (follicle-stimulating hormone), restoring hormonal balance.
Typical PCT dosage: 20 mg/day for 4 weeks.

Tamoxifen for Bodybuilders and Athletes
Tamoxifen is commonly included in PCT stacks with Clomiphene Citrate (Clomid) to restore hormonal balance and maintain muscle gains post-cycle.
Tamoxifen vs Aromatase Inhibitors
While Aromatase Inhibitors (AIs) like Anastrozole block estrogen production, Tamoxifen blocks estrogen receptor binding.
Tamoxifen is often preferred for PCT due to its milder hormonal rebound.
Clinical Studies Supporting Tamoxifen Use
- The ATLAS trial demonstrated a 29% reduction in breast cancer mortality after 10 years of Tamoxifen use.
- The NSABP B-14 study confirmed its efficacy in ER-positive cases.
