Tamoxifen Citrate, a nonsteroidal antiestrogen and selective estrogen receptor modulator, blocks estrogen’s effect on breast tissue, reducing DNA synthesis and preventing tumor growth by upregulating TGF-β and downregulating IGF-1 and PKC. Used in breast cancer treatment and prevention, it also aids post-cycle therapy for steroid-using athletes to prevent gynecomastia. Available in 10mg and 30mg capsules, typical doses range from 20-40mg daily. Side effects may include menstrual irregularities, dizziness, nausea, and increased uterine cancer risk. Store below 25°C, keep out of reach of children.
What is SP Tamoxifen?
SP Tamoxifen is a selective estrogen receptor modulator (SERM) used by bodybuilders to counteract the side effects of anabolic steroid cycles. It’s designed to help maintain muscle mass and prevent gynecomastia (male breast tissue growth) during post-cycle therapy.
How SP Tamoxifen Works
SP Tamoxifen works by binding to estrogen receptors in the body, blocking the action of estrogens. This helps to:
- Prevent gynecomastia and water retention
- Maintain muscle mass gained during steroid cycles
- Support natural testosterone production
SP Tamoxifen vs. Other SERMs
| SERM | Estrogenic Activity (E) | Progestogenic Activity (P) | Androgenic Activity (A) | Anti-Androgenic Activity |
|---|---|---|---|---|
| SP Tamoxifen | Mildly estrogenic at high doses | No progestogenic activity | None | Yes, blocks estrogen receptors |
| Raloxifene | Moderately estrogenic | Moderate progestogenic activity | None | Yes, blocks estrogen receptors |
SP Tamoxifen Dosage and Cycle Length
The typical dosage for SP Tamoxifen is 10-20mg per day. A common PCT protocol is:
- Weeks 1-2: 20mg/day
- Week 3: 10mg/day
