Nolvadex 20 mg – PCT & Gyno Protection
Active Ingredient: Tamoxifen Citrate
Manufacturer: Gen-Shi Laboratories
Pack Size: 100 Tablets (20 mg each)
Nolvadex 20 mg is a pharmaceutical-grade post-cycle therapy (PCT) and estrogen-blocking compound produced by Gen-Shi Laboratories. Each tablet contains 20 mg of Tamoxifen Citrate, a selective estrogen receptor modulator (SERM) widely used to prevent gynecomastia during steroid cycles and restore natural testosterone levels post-cycle.
Nolvadex is typically used in two main scenarios: on-cycle for estrogen receptor blockage, or post-cycle for testosterone recovery. Common PCT dosing looks like:
On-cycle, Nolvadex is used at 10–20 mg/day to manage early signs of gynecomastia or as an alternative to aromatase inhibitors.
Start Nolvadex approximately 2–3 days after your last dose of short esters, or 10–14 days after long esters. It's often combined with Clomid for enhanced recovery results.
Nolvadex 20 mg by Gen-Shi Laboratories is available at our online PCT and steroid store with verified authenticity, secure checkout, and fast shipping across the USA and internationally.
Not exactly. Arimidex prevents estrogen production, while Nolvadex blocks estrogen from binding to receptors. Nolvadex is better for PCT, Arimidex is better for on-cycle estrogen control.
Yes, indirectly. By blocking estrogen receptors, Nolvadex stimulates the pituitary to release more LH and FSH, which boosts natural testosterone production.
It can help reduce early-stage gynecomastia by blocking estrogen receptors, but it may not reverse severe or long-term glandular growth.
