Tamoxifen is a prescription medication that belongs to a class of drugs called selective estrogen receptor modulators (SERMs). It was originally developed to treat breast cancer but has also been used off-label by men to treat gynecomastia and improve testosterone production.
Tamoxifen works by binding to estrogen receptors throughout the body, thereby blocking the effects of the estrogen hormone. For breast cancer treatment, it slows or stops cancer growth that is estrogen-dependent.
In men, blocking estrogen provides beneficial effects in the pituitary gland and testes. Tamoxifen helps stop the estrogen-related negative feedback loop in the male hormonal system. This stimulates increased production of key hormones like testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH).
The result is reduced breast tissue enlargement (gyno), increased testosterone levels, and potentially greater muscle growth and performance enhancement benefits. It’s commonly used by bodybuilders and athletes for these purposes.
Benefits of Tamoxifen
Research shows Tamoxifen can provide the following beneficial effects in men:
- It treats and prevents gynecomastia caused by high estrogen levels
- It boosts serum testosterone and gonadotropins (FSH and LH).
- Reduces estrogen conversion from aromatase enzyme
- Stimulates greater release of luteinizing hormone
- Enhances muscle growth and athletic performance
By managing estrogen activity and optimizing androgen status, Tamoxifen helps restore hormonal balance. The end result is a reduction in female-pattern fat storage and an enhancement of masculine muscle growth characteristics.
Side effects of Tamoxifen
Some potential side effects of tamoxifen may include:
- Headaches, dizziness, and fatigue
- Hot flashes, increased sweating
- Nausea, vomiting, upset stomach
- Mood changes like depression or irritability
- Sleep problems like insomnia
Rare but serious side effects can include blood clots, strokes, uterine cancer, and eye damage. Seek prompt medical attention for any concerning symptoms after starting tamoxifen. Inform your doctor of any side effects to determine proper management.
Tamoxifen Daily Dosage
When used for gynecomastia, the typical tamoxifen dosage is 20–40 mg per day. It’s commonly taken as a single daily dose or split into two divided doses of 10–20 mg each. The full effects may take 2-3 months, so it needs to be run for at least several months to see results.
For PCT after a steroid cycle, tamoxifen is taken for 4–6 weeks at the same dosage of 20–40 mg daily. It helps restart natural testosterone production that has been suppressed during the cycle.
Taking doses with food can help minimize any stomach upset. Be consistent from day to day with timing. Splitting the daily dose of AM and PM can help maintain steady blood levels. Follow medical advice, and never exceed 40 mg daily.
Where to Buy Tamoxifen Online
Tamoxifen is a prescription medication, so you can obtain it from a pharmacy, doctor’s office, or hospital with a valid prescription. However, it is also available for purchase from some peptide and research chemical websites that sell to customers globally.
If buying online, only order from trustworthy suppliers with excellent customer service, guaranteed delivery, and third-party verification of product quality. Make sure the website has secure checkout and encryption to protect your financial and personal information. Compare pricing from different vendors to find good value.
When acquiring any medications through unofficial channels, keep orders small and infrequent and avoid stockpiling large quantities. Consult a medical professional for proper dosing and oversight when using substances bought online without a local doctor’s prescription.
