Buy Nolvadex 20 mg – Gen-Shi Laboratories Tamoxifen Citrate (100 Tablets)

Nolvadex 20 mg by Gen-Shi Laboratories delivers pharmaceutical-grade Tamoxifen Citrate at 20 mg per tablet, with 100 tablets per bottle. Nolvadex is a widely used SERM that helps prevent and reverse gynecomastia, and supports natural testosterone recovery during PCT.

What Is Nolvadex (Tamoxifen Citrate)?

Tamoxifen is a selective estrogen receptor modulator (SERM) that blocks estrogen in certain tissues (like breast tissue) while maintaining its function elsewhere. In bodybuilding, it's used both during cycles (for gyno prevention) and after cycles (for post-cycle therapy) to restore hormonal balance.

Benefits of Nolvadex 20 mg

  • Prevents and reduces estrogen-induced gynecomastia
  • Supports testosterone production post-cycle
  • Preserves fertility and libido during recovery
  • Improves LH and FSH release

How to Use Nolvadex

For PCT:

  • Weeks 1–2: 40 mg/day
  • Weeks 3–4: 20 mg/day

Start PCT 1–2 weeks after the final injection of long esters or 2–3 days after short-acting orals. You can also use Nolvadex on-cycle if signs of gyno appear.

Popular PCT Stacks

  • Clomid – for dual-SERM synergy
  • Arimidex – for estrogen management during cycle

Frequently Asked Questions

Can Nolvadex prevent gynecomastia during a cycle?

Yes. Nolvadex can block estrogen in breast tissue and is effective for preventing or reversing early gyno symptoms during steroid cycles.

Is Nolvadex enough for PCT on its own?

Yes, for many users. But combining with Clomid may improve results by acting through multiple hormonal pathways.

What's the difference between Nolvadex and Arimidex?

Nolvadex is a SERM that blocks estrogen receptors. Arimidex is an AI that lowers total estrogen levels. Both have different on-cycle and PCT uses.
