01The basics

What Nolvadex by Genetix Pharma is

Genetix Pharma’s Nolvadex contains tamoxifen citrate, 20 mg per tablet with 50 tablets per bottle. Tamoxifen is one of the most studied drugs in medicine, used for breast cancer since the 1970s.

For men, it’s the go-to drug for early gynecomastia and a standard part of post-cycle therapy. It’s usually well tolerated in short courses, but its blood clot risk means it isn’t right for everyone.

03How it works

How it works

Tamoxifen is a SERM: it blocks estrogen receptors in some tissues and activates them in others.

  • Breast tissue: blocks estrogen, which shrinks early gynecomastia.
  • Brain: blocks estrogen feedback, so LH and FSH rise and the testes restart testosterone production.
  • Liver and bone: acts like estrogen, which helps bones but raises clotting risk.

Its half-life of about 5–7 days means it takes a couple of weeks to reach steady levels.

04Half-life

Half-life, in plain numbers

A half-life of about 5-7 days means half of what is in the body is gone after that time, then half of the rest, and so on. For a tablet this is mostly about how fast the liver clears it; food and the person change it a little.

05Clinical reference

Dosing information

Clinical reference. For breast cancer, tamoxifen is 20 mg once a day. For gynecomastia, studies in men have used 10–20 mg a day for about three months. PCT use is off-label.

One Genetix tablet is 20 mg. Talk to a doctor before use.

06Measure it

Measure it

08Risks

Side effects and risks

Short courses are usually uneventful; know the warning signs anyway.

Blood clots

Pain or swelling in one leg, chest pain or sudden shortness of breath needs emergency care.

Eyes

Rare cataracts or retinal changes. Report blurred or changed vision.

Hot flashes and mood

Hot flashes, tiredness or low mood are reported in some men.

Liver

Occasional rises in liver enzymes.

For women

Long-term use raises uterine cancer risk; report abnormal bleeding.

Don’t use it if you

Have had a blood clot or stroke, have a clotting disorder, take warfarin, are pregnant or breastfeeding.

09Interactions

Interactions

Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.

  • SeriousWarfarin

    Tamoxifen strongly boosts warfarin. The pairing is avoided, or INR is watched very closely.

  • CautionParoxetine, fluoxetine, bupropion, quinidine

    They block CYP2D6, the liver enzyme that turns tamoxifen into its active form (endoxifen), so tamoxifen can work less well.

  • CautionAnastrozole and letrozole

    Tamoxifen lowers anastrozole levels; in breast-cancer treatment the two are not given together.

  • Good to knowEstrogen products

    Birth control pills and hormone therapy work against tamoxifen.

  • Good to knowBlood clots

    Smoking, long flights and immobility add to tamoxifen’s own clot risk.

10Bloodwork

Bloodwork checklist

Test before PCT and 4–6 weeks after you finish.

  • Testosterone, LH, FSH
  • Estradiol
  • Liver panel and lipids

11Uses

How it fits after a cycle

Tamoxifen is started once the steroids have cleared, from a few days after short esters to about three weeks after decanoate. Some protocols pair it with clomiphene (Clomid). For gynecomastia, it works best on new, tender tissue; firm tissue that’s been there for months often needs surgery. See Pairs well with below.
