ANCILLARIES

Ancillaries are the support compounds used alongside testosterone and anabolic cycles to keep hormones in balance — controlling estrogen while on-cycle and helping restore the body’s natural hormone production afterwards. At KGEAR U.S, every ancillary in this collection is third-party HPLC lab-tested for verified identity and purity.

Aromatase Inhibitors (AIs) — Estrogen Control

When testosterone aromatizes into estrogen, side effects like water retention, gynecomastia, and mood swings can follow. Aromatase inhibitors block that conversion to keep estrogen in a healthy range. Our AI range includes Arimidex (Anastrozole) 1 mg, a reversible non-steroidal AI, and Aromasin (Exemestane) 25 mg, an irreversible steroidal AI — two of the most widely used estrogen-management tools.

SERMs — Post-Cycle Therapy (PCT)

Selective estrogen receptor modulators (SERMs) are the foundation of post-cycle therapy, helping kick-start natural testosterone production once a cycle ends. This category includes Nolvadex (Tamoxifen) 20 mg, Clomid (Clomiphene) 50 mg, and Enclomiphene 20 mg — each used to support hormonal recovery and protect gains after a cycle.

Additional Support Compounds

Beyond AIs and SERMs, our ancillaries range covers other on-cycle support needs, including Cabergoline (Caber) 0.25 mg for managing prolactin on 19-nor compounds. Together, these tools help you run a cleaner cycle and recover more effectively.

On-Cycle vs. Post-Cycle

On-cycle, aromatase inhibitors like Arimidex and Aromasin keep estrogen controlled while your testosterone or anabolics are active. Post-cycle, SERMs like Nolvadex and Clomid help the body resume its own testosterone production. Choosing the right ancillary depends on the compounds you’re running and your individual response — always under the guidance of a qualified healthcare professional.

Why Buy Ancillaries From KGEAR U.S

Purity matters most with support compounds, because under-dosed or mislabeled ancillaries can leave estrogen uncontrolled or PCT ineffective. Every KGEAR U.S ancillary is HPLC-verified, with lab reports published on our test reports page, and shipped domestically within the USA. Browse the full ancillaries collection below.
