Why use Tamoxifen and Clomiphene together?

Clomiphene stimulates LH/FSH at the pituitary level, while Tamoxifen protects breast tissue and improves blood lipid values. The combination addresses both PCT goals that a single SERM covers only partially.

When should I start PCT after a Testosterone Enanthate cycle?

2–3 weeks after the last injection. With Enanthate's half-life of 4–5 days, levels will have dropped far enough after 2–3 weeks for PCT to take effect.

Is this bundle enough for a heavy cycle?

After cycles involving Nandrolone or Trenbolone we recommend the extended PCT Complete Protocol with HCG – 19-nor compounds suppress the axis more strongly and for longer.

What should I do if I experience visual disturbances while taking Clomiphene?

Discontinue Clomiphene immediately and continue with Tamoxifen only. Visual disturbances under Clomiphene are rare but are an absolute reason to stop.

How long does full recovery take?

After moderate cycles, the hormonal axis typically normalises within the 4 PCT weeks plus 2–4 weeks thereafter. Your follow-up blood panel gives the definitive answer.

Concentrex PCT Protocol is a pre-configured post-cycle bundle containing 1× TamoTrex 20 mg and 1× CloTrex 50 mg – the classic dual-SERM combination from Concentrex Labs for a 4-week post-cycle therapy.

Why Two SERMs Instead of One

Clomiphene acts primarily at the pituitary gland: it blocks oestrogen receptors there, causing the body to register an oestrogen deficit and increase the release of LH and FSH – the signal the testes need to resume testosterone production. Tamoxifen adds support on two levels: it blocks oestrogen receptors in breast tissue (gynaecomastia protection during the sensitive post-cycle phase) and has been shown to improve the lipid profile, which is typically compromised after a cycle.

The Tapered 4-Week Schedule

The first 2 weeks run at full dosage (Tamoxifen 20 mg, Clomiphene 50 mg daily); weeks 3–4 use a halved dose. This tapering structure reduces the typical Clomiphene side effects (mood swings, visual disturbances) while maintaining the same stimulatory effect.

Who This Protocol Is For

Users coming off moderate cycles – Testosterone solo, Testosterone plus one oral compound, or short esters up to 10 weeks. After heavier cycles involving 19-nor compounds (Nandrolone, Trenbolone) we recommend the extended PCT Complete Protocol with HCG.

Usage

Determine your PCT start date based on the half-life of the last compound in your cycle (short esters: 3–4 days after last use; long esters: 2–4 weeks after the last injection).
Take TamoTrex and CloTrex daily at the same time, with a meal.
Halve the dosage at the start of week 3 exactly as shown in the table – do not discontinue earlier.
Avoid alcohol throughout the entire PCT to support liver recovery.
Get a follow-up blood panel in weeks 4–5 (total testosterone, LH, FSH, oestradiol).
Begin a new cycle only after full hormonal recovery – rule of thumb: cycle length plus PCT length as minimum rest.

Warnings

Contraindications

Do not use if you have a known hypersensitivity to SERMs, existing liver disease, a history of thrombosis, or if you are pregnant or breastfeeding. Clomiphene is contraindicated in the presence of visual disturbances.

Side Effects

Clomiphene may cause mood swings, hot flushes, and rarely visual disturbances (light flashes, blurred vision) – discontinue immediately if visual disturbances occur. Tamoxifen may cause hot flushes and gastrointestinal discomfort. Both active substances are well documented and have been established in clinical medicine for decades.

Monitoring

Obtain a follow-up blood panel in weeks 4–5: total testosterone, LH, FSH, and oestradiol. If testosterone remains below the reference range, extend PCT by 2 weeks and consult a physician.

PCT

This bundle is the PCT itself. After heavy cycles involving 19-nor compounds or cycles exceeding 12 weeks, we recommend the extended PCT Complete Protocol with an HCG component.
