01The basics
What Zionova Nolvadex is
Nolvadex is the brand name for tamoxifen, a SERM (selective estrogen receptor modulator) that has been used to treat and prevent breast cancer since the 1970s. Each Zionova tablet contains 20 mg of tamoxifen citrate, with 50 tablets per bottle.
In men, tamoxifen is used off-label to treat gynecomastia and to restart natural testosterone production after a steroid cycle. It’s well studied, but it isn’t harmless: it raises the risk of blood clots and has other effects you should know about.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.

03How it works
How it works
Tamoxifen blocks estrogen in some tissues and mimics it in others.
- In breast tissue, it blocks estrogen, which is why it treats breast cancer and early gynecomastia.
- In the brain, blocking estrogen’s feedback makes the pituitary release more LH and FSH, which tells the testes to make testosterone again.
- In the liver and bone, it acts more like estrogen, which can improve some cholesterol numbers but also raises clotting risk.
Its half-life is about 5–7 days, so levels build up over the first weeks.
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.
- One half-life
- 6 days
- About 97% gone
- 30 days
- Levels level out with regular use after
- 24 days–30 days
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. For breast cancer, the standard dose is 20 mg once a day, usually for 5–10 years. For gynecomastia, studies in men have used 10–20 mg a day for about 3 months. Its use for PCT is off-label, and there’s no official dose.
One Zionova tablet is 20 mg. Talk to a doctor before use, particularly if you have any clotting risk.
06Measure it

Add to cart08Risks
Side effects and risks
Most men tolerate tamoxifen well for short courses, but a few risks are serious.
Blood clots
Tamoxifen raises the risk of deep vein thrombosis and pulmonary embolism. Leg swelling or pain, chest pain or sudden breathlessness needs emergency care.
Vision changes
Rarely, it affects the eyes (cataracts, retinal changes). Report blurred vision or changes in colour vision.
Hot flashes and mood
Hot flashes, low mood, fatigue and reduced libido are reported in some men.
Liver
Liver enzymes occasionally rise, and fatty liver has been linked to long-term use.
For women
Long-term use raises the risk of uterine cancer. Abnormal vaginal bleeding needs a doctor promptly.
Don’t use it if you
Have had a blood clot or stroke, have a clotting disorder, take warfarin, are pregnant or breastfeeding, or are under 18 without a specialist.
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
For PCT, test before you start and 4–6 weeks after you finish to confirm recovery.
- Hormones: total and free testosterone, LH, FSH, estradiol
- Liver panel: ALT, AST
- Lipid panel
- CBC
11Uses
How it fits after a cycle
After steroids, natural testosterone is suppressed because the brain stopped sending LH and FSH. Tamoxifen helps restart that signal. It’s usually started once the steroids used have cleared, which ranges from a few days for short esters to about three weeks for long ones such as decanoate. Clomid (clomiphene) works similarly and is sometimes used instead of or alongside it. Bloodwork after PCT shows whether your own production has returned.

14Questions
Common questions
Nolvadex or Clomid for PCT?
Both are SERMs that restart LH and FSH. Tamoxifen is often better tolerated; clomiphene can cause visual disturbances and mood changes in some men. Some protocols use one, some use both.
Can Nolvadex reverse gynecomastia?
It works best on new, tender breast tissue. Established, firm tissue that has been there for months usually doesn’t respond and may need surgery.
Does Nolvadex lower estrogen?
No. It blocks estrogen at certain receptors but doesn’t lower estrogen levels in the blood; that’s what aromatase inhibitors like Arimidex do.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is Nolvadex legal in Canada?
Tamoxifen is a prescription drug in Canada (on Health Canada’s Prescription Drug List). It isn’t a controlled substance.
How is my order packaged?
In a plain, unbranded box with no product names on the outside.
