What Each Compound Does
Testosterone Elevation
Sustained testosterone support through the undecanoate ester's sustained-release profile — no spikes, no crashes.†
Lean Muscle Mass
Increased anabolic potency drives lean tissue growth and strength gains without significant water retention.†
Strength Output
Elevated androgenic activity supports progressive strength gains over the course of supplementation.†
Improved Libido
Testosterone support may enhance mood, sexual drive, and overall sense of well-being during use.†
Reduced Estrogen Risk
The undecanoate ester's pathway results in less aromatization compared to standard 4-Andro esters.†
Year-Round Use
Unlike most prohormones, Andriol can be taken continuously for the majority of men — no mandatory off-cycle breaks.†
Dosing & Cycle Parameters
Take 1 tablet in the morning with food. Andriol can be used year-round for the majority of men and does not require a traditional on/off cycle. When you decide to discontinue use, run a minimum 4-week PCT. If estrogen-related side effects occur during use, add Arimistane on-cycle.
PCT Required When You Stop
A minimum 4-week PCT is required whenever you discontinue Andriol. PCT restores natural testosterone production, rebalances hormones, and preserves your gains. Arimiplex is the recommended PCT for Andriol cycles — especially after extended use.
Shop Arimiplex PCT → Shop Novedex XT →Add Liver-RX — On-Cycle Liver Support
Andriol is non-methylated and partially absorbed via the lymphatic system — gentle on the liver compared to methylated compounds. That said, on-cycle liver support is always recommended during any prohormone protocol. Liver-RX supports detoxification and healthy liver enzyme levels. 90ct — $14.99, full-cycle coverage.

Possible Side Effects:
Potential for mild estrogen conversion (aromatization). Side effects may include acne, increased facial hair, mood changes, or libido shifts.

Sports Testing Notice:
This product may contain ingredients banned by some sports organizations or may increase the risk of a false positive on drug tests. Consult your sports organization or physician before use.
Is this the same as the anabolic steroid Andriol (Testosterone Undecanoate)?
No. The prescription anabolic steroid Andriol contains pharmaceutical-grade Testosterone Undecanoate. Hi-Tech Pharmaceuticals Andriol is a legal dietary supplement prohormone — not a controlled substance and not a prescription drug. It is a 4-Andro compound designed to support testosterone levels through a two-step conversion process.†
Is Andriol a steroid?
No — Andriol is a prohormone, not a steroid. It is a legal dietary supplement sold without a prescription. Prohormones are precursor compounds that convert to active hormones in the body, which is different from the direct administration of anabolic steroids.
Do I need to cycle Andriol on and off?
According to Hi-Tech Pharmaceuticals, Andriol can be taken year-round for the majority of men and does not require mandatory cycling. However, when you decide to stop using it, a minimum 4-week PCT with Arimiplex is required to restore natural hormone production.
Do I need PCT after Andriol?
Yes — PCT is required whenever you discontinue Andriol. Arimiplex is the recommended PCT. For extended use, a full PCT stack is advisable. PCT helps restore hormonal balance, reduces side effects, and preserves your gains.†
Will Andriol increase estrogen?
There is some potential for estrogen conversion due to the 4-Andro pathway, but the undecanoate ester results in less aromatization compared to shorter 4-Andro esters. If you experience estrogen-related side effects, adding Arimistane on-cycle is a sound option. Arimiplex PCT at the end of your cycle will handle estrogen rebalancing.†
How is Andriol different from Sustanon 250?
Both products contain the 4-Andro compound. The key difference is the ester: Andriol uses 158mg of Undecanoate — a long, smooth ester that produces a sustained, even release. Sustanon 250 uses a 250mg blend of multiple 4-Andro esters, with only 30mg of Decanoate. Sustanon 250 must be cycled (maximum 8 weeks), while Andriol can be taken year-round.†
Can women use Andriol?
No. Female use is not recommended. Andriol significantly increases androgenic and anabolic hormone activity. Virilization effects in women — including increased facial hair and voice changes — are possible. Not for use by females, especially pregnant or nursing women.
Is this a dietary supplement?
