Tamoxifen 20 mg (Nolvadex)

The medicine is produced by evolve biolabs, based on the active ingredient tamoxifen citrate (Nolvadex). This medicine is used in medicine to treat cancer in front of the woman. The medicine is also boldly used by muscular men as a post-cycle therapy medicine after a steroid cycle.
Advantages of the Tamoxifen 20 mg (Nolvadex)
When tamoxifen 20 is used correctly, the effects that the medicine can produce are:
- HPT axis restoration
- Preserve the muscle mass gained thanks to a steroid cycle
- Restore the body’s testosterone production
- Prevent gynecomastia and other aromatization-related side effects
Tips for use
DO NOT use Tamoxifen 20 for PCT if progestin steroids such as trenbolone, nandrolone or Oxymetholone have been taken in the cycle. This can lead to progestin-related side effects. In this case another antiestrogenic drug such as clomiphene citrate should be used.
Tamox should be taken at a dose of 20 mg per day. Tamoxifen is generally started the day after completing a steroid cycle, although, if long-acting, slow-acting ester-based steroids are used, you should wait two weeks after the last injection to start taking tamoxifen.
Side effects
Possible side effects of Tamoxifen Citrate Tamox include menstrual disorders, prostate problems, male pattern baldness, mood swings and hypertension.

Faqs
What is Tamox (Tamoxifen 20 mg)?
Tamox contains Tamoxifen Citrate (commonly known as Nolvadex), a selective estrogen receptor modulator (SERM). In bodybuilding, it’s used to block estrogen effects in certain tissues (like breast tissue) while allowing some estrogen activity elsewhere.
What is Tamox used for in bodybuilding?
Primarily to prevent and treat gynecomastia (gyno / “bitch tits”) caused by aromatizing steroids, and as a key component of PCT to stimulate natural testosterone production after a cycle by blocking estrogen feedback at the hypothalamus/pituitary.
Does Tamox prevent gynecomastia on cycle?
Yes — it’s one of the most effective SERMs for preventing and reversing early-stage estrogen-induced gynecomastia during cycles with compounds like testosterone, Dianabol, or Deca.
What is the typical dosage of Tamox for gyno prevention?
10–20 mg per day (often 10–20 mg daily or every other day) during a cycle when estrogen symptoms appear. Start low and adjust based on symptoms; higher doses (up to 40 mg) are sometimes used short-term for active gyno.
What is the standard Tamox dosage for PCT?
Common protocol: Weeks 1–2: 40 mg/day; Weeks 3–4: 20 mg/day (sometimes extended to 20 mg for 4–6 weeks total). Often combined with Clomid for stronger recovery.
How long should Tamox be used in PCT?
Typically, 4–6 weeks, starting immediately after the last steroid dose (or when short-ester compounds clear). Duration depends on cycle length and suppression level.
Does Tamox have side effects?
Yes — common include hot flashes, nausea, headaches, mood swings/irritability, fatigue, reduced libido (in some users), and rare visual disturbances. It can also raise SHBG and potentially cause estrogen rebound if stopped abruptly.
Is Tamox suppressive to natural testosterone?
No — it actually helps restore testosterone by blocking negative estrogen feedback. However, improper use or rebound can temporarily disrupt hormones.
When should I expect results from Tamox?
For gyno prevention/reversal: symptom reduction (nipple sensitivity, puffiness) often within days to 1–2 weeks. For PCT: testosterone rebound begins within 1–2 weeks, with full recovery taking 4–8 weeks depending on cycle.
Is Tamox suitable for beginners?
Yes, it’s considered mild and beginner-friendly for gyno control or basic PCT but always start at lower doses (10–20 mg) and monitor symptoms/bloodwork. Blood tests are highly recommended.
