Equipoise vs Andriol: An In-Depth Overview of Two Anabolic Steroids

What is Equipoise?

Equipoise, scientifically known as Boldenone Undecylenate, is an anabolic androgenic steroid (AAS) originally developed for veterinary use—most notably for horses. Structurally derived from testosterone, Equipoise was first synthesized and introduced by the pharmaceutical company Ciba in the 1960s.

Its core function is to enhance lean muscle mass, strength, and endurance, making it a popular choice among bodybuilders and athletes. Unlike fast-acting steroids, Equipoise features an undecylenate ester, allowing it to be released slowly into the bloodstream after intramuscular injection. This slow-release mechanism enables fewer injections—often only once or twice per week—making it more manageable for long-term cycles.

Equipoise’s mild androgenic properties also make it a more favorable option for those sensitive to androgenic side effects such as acne or hair loss. This makes it appealing not just for male athletes but occasionally for women under medical supervision.

One of the most beneficial effects of Equipoise is its ability to increase nitrogen retention in muscle tissue, which directly supports muscle hypertrophy and recovery. Additionally, it stimulates erythropoiesis, or red blood cell production, which improves oxygen delivery to working muscles. This enhances both aerobic performance and recovery time.

“Boldenone increases red cell mass and muscle mass by enhancing nitrogen balance and erythropoiesis.” — Hartgens & Kuipers, Sports Medicine

What is Andriol?

Andriol, also known as Testosterone Undecanoate, is a unique oral form of testosterone that serves as both a testosterone replacement therapy (TRT) agent and a performance-enhancing compound. It was developed by Organon in the 1980s to address one of the major limitations of oral steroids: liver toxicity.

Unlike most oral steroids that are rapidly degraded by the liver (first-pass metabolism), Andriol is absorbed through the intestinal lymphatic system, significantly improving its bioavailability and reducing hepatic strain.

“Oral testosterone undecanoate bypasses hepatic first-pass metabolism via lymphatic absorption, resulting in more stable serum testosterone levels.” — Bagchus et al., European Journal of Endocrinology

This delivery method makes Andriol a more liver-friendly alternative for individuals requiring testosterone therapy or those who prefer oral administration over injections.

Once ingested, Andriol is converted into active testosterone, which exerts anabolic and androgenic effects throughout the body. Its benefits include:

• Muscle growth and strength enhancement

• Improved bone density

• Enhanced libido and mood

• Support for general well-being and energy levels

Because of its convenient capsule form, Andriol is favored among users new to testosterone or those hesitant about needles. However, it does require multiple doses daily to maintain stable testosterone levels due to its relatively short half-life.

Mechanism of Action: How Each Compound Works

How Equipoise Works in the Body

Equipoise (Boldenone Undecylenate) operates through a well-understood anabolic mechanism by binding to androgen receptors within skeletal muscle tissue. Once bound, this interaction stimulates protein synthesis, the process through which cells generate new proteins, primarily in the form of muscle tissue.

Another key effect of Equipoise is its ability to enhance nitrogen retention. Maintaining a positive nitrogen balance is crucial for building lean muscle mass. This anabolic environment helps the body remain in a state where muscle hypertrophy (growth) is prioritized over muscle breakdown (catabolism).

Additionally, Equipoise promotes erythropoiesis, the stimulation of red blood cell production. More red blood cells mean improved oxygen delivery to working muscles, which contributes to better endurance, stamina, and recovery during high-intensity training sessions.

“Anabolic steroids like Boldenone increase protein synthesis and erythropoiesis, contributing to muscle growth and improved physical performance.” — Hartgens & Kuipers, Sports Medicine

How Andriol Works in the Body

Andriol (Testosterone Undecanoate) works differently due to its unique oral formulation. Unlike other oral steroids, Andriol bypasses first-pass liver metabolism by being absorbed via the intestinal lymphatic system. This absorption route protects the active ingredient from early breakdown and allows it to enter systemic circulation more efficiently.

Once in the bloodstream, Andriol is converted into bioactive testosterone, which binds to androgen receptors throughout the body. Elevated testosterone levels result in a cascade of anabolic effects, including:

• Increased protein synthesis

• Improved nitrogen retention

• Enhanced muscle hypertrophy

• Greater bone density and libido

• Better mood and cognitive function

“Testosterone undecanoate is effective in restoring physiological testosterone concentrations, promoting muscle protein anabolism and improving physical and sexual health.” — Bagchus et al., European Journal of Endocrinology

Key Differences in Their Mechanisms

While both compounds aim to enhance muscle growth and physical performance, they do so through different biochemical pathways:

• Equipoise enhances anabolic activity primarily through protein synthesis, nitrogen retention, and red blood cell stimulation.

• Andriol increases circulating testosterone levels, which activates a wide range of anabolic and androgenic processes.

This distinction makes Equipoise more suitable for users seeking longer-lasting, injectable cycles with endurance benefits, while Andriol is better for those looking for a convenient oral option with broad-spectrum testosterone replacement effects.

Benefits of Equipoise vs Andriol for Muscle Gains

Benefits of Equipoise for Muscle Gains

Equipoise (Boldenone Undecylenate) is highly regarded in the performance-enhancing community for its ability to promote lean muscle mass without excessive water retention. This is especially appealing to bodybuilders and physique athletes who aim to achieve muscle definition, vascularity, and a hard, dry appearance.

Key Benefits of Equipoise:

• Steady anabolic environment: Its long-acting undecylenate ester ensures a gradual and sustained release, maintaining stable blood levels and promoting slow, clean muscle gains over time.

• Increased strength and endurance: Equipoise significantly enhances red blood cell production (erythropoiesis), which improves oxygenation and muscular endurance. This results in better stamina during training, allowing users to push harder and recover faster.

• Reduced androgenic side effects: Compared to more potent androgens, Equipoise has mild androgenic properties, minimizing risks such as:

  • Acne

  • Aggression

  • Hair loss

“Boldenone use increases lean body mass, oxygen delivery, and strength while minimizing common androgenic side effects.” — Hartgens & Kuipers, Sports Medicine

• Lower estrogenic activity: Equipoise aromatizes at a very low rate, which means reduced risk of estrogen-related side effects such as:

  • Gynecomastia (male breast tissue)

  • Excessive water retention

This balance of anabolic efficiency and low side effect profile makes Equipoise a preferred compound for cutting cycles, lean bulking, and endurance athletes alike.

Benefits of Andriol for Muscle Gains

Andriol (Testosterone Undecanoate) stands out due to its oral administration and unique lymphatic absorption, making it a practical and safer option for many users. Its benefits go beyond just muscle growth, contributing to overall hormonal health and performance.

Key Benefits of Andriol:

• Convenient oral delivery: Andriol is taken in capsule form, which removes the need for injections and allows:

Side Effects and Risks of Equipoise vs Andriol

Side Effects and Risks of Equipoise

While Equipoise (Boldenone Undecylenate) offers benefits like lean muscle growth and improved endurance, it also carries a range of side effects that require careful monitoring and responsible use.

1. Testosterone Suppression

Like most anabolic steroids, Equipoise suppresses natural testosterone production. Prolonged use can result in hypogonadism, with symptoms such as:

• Decreased libido

• Lethargy or chronic fatigue

• Mood instability

• Muscle mass loss

This suppression occurs due to negative feedback on the hypothalamic-pituitary-gonadal (HPG) axis, which shuts down endogenous hormone signaling.

“Use of anabolic steroids such as Boldenone leads to suppression of the HPG axis, impairing endogenous testosterone production.” — Nieschlag et al., The Lancet Diabetes & Endocrinology

To combat this, users typically follow a post-cycle therapy (PCT) protocol with agents like Clomid or Nolvadex.

2. Androgenic Side Effects

Equipoise may cause androgen-related issues, particularly in genetically predisposed individuals:

• Acne and oily skin

• Scalp hair thinning or male-pattern baldness

• Increased body hair growth

Though milder than compounds like Trenbolone, Equipoise is still an androgen, and dose management is key to minimizing these effects.

3. Cardiovascular Risks

Equipoise can negatively affect cholesterol levels by:

• Reducing HDL ("good") cholesterol

• Increasing LDL ("bad") cholesterol

This lipid imbalance may increase the risk of atherosclerosis and heart attack, particularly during long or high-dose cycles.

“Anabolic steroids have been shown to alter lipid metabolism, decreasing HDL-C and increasing LDL-C levels.” — Thompson et al., JAMA

To reduce these risks:

• Follow a heart-healthy diet (high in omega-3s and fiber)

• Incorporate cardiovascular exercise

• Monitor lipid panels regularly during cycles

---

Side Effects and Risks of Andriol

Andriol (Testosterone Undecanoate) is considered a safer oral testosterone option, but like any exogenous hormone, it carries certain risks.

1. Testosterone Suppression

Although gentler than injectable esters, Andriol can still suppress endogenous testosterone when used long term. Symptoms may include:

• Mood swings

• Decreased libido

• Erectile dysfunction

• Fatigue and depressive symptoms

PCT is essential following a cycle to reestablish natural hormonal balance.

2. Estrogenic Side Effects

Since Andriol elevates testosterone levels, some of it may convert to estrogen via aromatase, which can lead to:

• Gynecomastia (male breast tissue development)

• Water retention and bloating

• Increased fat storage

Sensitive individuals may consider using an aromatase inhibitor (AI) like Arimidex during their cycle to keep estrogen levels under control.

“Testosterone supplementation increases estradiol levels via aromatization, contributing to estrogenic side effects unless controlled.” — Bhasin et al., New England Journal of Medicine

3. Cardiovascular Effects

Despite its unique lymphatic absorption, Andriol still impacts lipid profiles similarly to other androgens:

• Reduced HDL cholesterol

• Elevated LDL cholesterol

This can result in long-term cardiovascular risk if not addressed with lifestyle adjustments and monitoring.

“Oral testosterone undecanoate has been shown to reduce HDL cholesterol, raising concern for long-term cardiovascular outcomes.” — Corona et al., The Journal of Sexual Medicine

---

Post-Cycle Therapy (PCT) for Equipoise and Andriol

Why PCT Is Essential

Both Equipoise and Andriol suppress the body's natural production of testosterone. Without intervention, this suppression can lead to hypogonadism, resulting in:

• Fatigue

• Depression

• Low libido

• Muscle loss

• Hormonal imbalance

A well-structured PCT helps restore endogenous testosterone production, rebalance estrogen, and preserve the gains made during the cycle.

---

When to Start PCT

Compound	Time After Last Dose to Start PCT
Equipoise	14–21 days post-cycle (long ester)
Andriol	3–5 days post-cycle (shorter clearance)

Equipoise requires a longer waiting period due to its undecylenate ester, which stays active in the body for up to 3 weeks. Starting PCT too early will be ineffective. Andriol clears more quickly, allowing earlier initiation of therapy.

---

Recommended PCT Protocol

Phase 1: SERM-Based Recovery (Weeks 1–4)

Use Selective Estrogen Receptor Modulators (SERMs) to restart luteinizing hormone (LH) and follicle-stimulating hormone (FSH) production:

• Clomid (Clomiphene Citrate)

  • Week 1–2: 50 mg/day

  • Week 3–4: 25 mg/day

OR

• Nolvadex (Tamoxifen Citrate)

  • Week 1–4: 20 mg/day

These medications stimulate the pituitary gland to resume natural testosterone production.

“Clomiphene and Tamoxifen effectively stimulate endogenous testosterone in hypogonadal men.” — Guay et al., Journal of Andrology

---

Phase 2: Natural Hormonal Support (Weeks 1–8)

Use natural supplements to assist recovery, boost free testosterone, and manage cortisol:

• Swolverine ZMT

  • Dose: 6 capsules nightly

  • Purpose: Improves sleep, supports testosterone with zinc, magnesium, DHEA, and vitamin B6

  • Includes adaptogens and recovery support

• Swolverine DHEA

  • Dose: 100 mg daily

  • Purpose: Supports mood, hormonal balance, and adrenal recovery

  • Can help bridge the gap while endogenous production stabilizes

• Ashwagandha or Rhodiola (optional)

  • Helps reduce stress-induced cortisol, which may suppress testosterone

---

Optional Phase 3: Estrogen Control (If Needed)

If estrogen rebound occurs (bloating, mood changes, gynecomastia), consider a short-term Aromatase Inhibitor (AI):

• Arimidex (Anastrozole): 0.25 mg every other day (2 weeks max)

  • Only use if estrogenic symptoms arise

  • Do not suppress estrogen too aggressively, as it plays a role in recovery

---

Monitoring and Bloodwork

To ensure proper recovery:

• Pre-cycle labs: Establish your baseline

• Mid-PCT labs: Check total/free testosterone, LH/FSH, estradiol, SHBG

• 8-week post-PCT labs: Confirm full recovery before any future cycle

---

Summary of PCT Goals

✅ Restart natural testosterone
✅ Control estrogen rebound
✅ Preserve lean muscle and strength
✅ Normalize mood, libido, and energy
✅ Protect cardiovascular and hormonal health

Comparing Dosages and Administration Methods: Equipoise vs Andriol

Equipoise Dosage and Administration

Equipoise (Boldenone Undecylenate) is administered via intramuscular injection, typically once or twice weekly due to its long half-life of approximately 14 days. This slow-release profile maintains stable plasma levels over extended periods, which is beneficial for sustained anabolic effects and user convenience.

Common Equipoise Dosage:

• Beginner: 200–300 mg/week

• Intermediate: 400–600 mg/week

• Advanced: Up to 800 mg/week (not commonly recommended due to risk escalation)

The infrequent injection schedule is often seen as a plus, especially when compared to fast-acting esters like testosterone propionate that require near-daily administration.

“Due to its ester structure, Boldenone Undecylenate allows for infrequent injections and stable serum concentrations.” — Kicman, British Journal of Pharmacology

However, being injectable means it’s not ideal for users averse to needles or who lack proper technique for self-administration.

Andriol Dosage and Administration

Andriol (Testosterone Undecanoate) is unique among anabolic agents because it comes in oral capsule form, absorbed via the intestinal lymphatic system rather than the liver. This avoids first-pass metabolism, improving bioavailability and reducing liver strain.

Typical Andriol Dosage:

• Mild TRT or performance enhancement: 120–160 mg/day

• Divided dosing: Usually split into 2–3 doses per day, taken with dietary fat for optimal absorption

Andriol’s daily dosing schedule enables more precise control over serum testosterone levels but may require multiple pills per day to sustain therapeutic benefit.

“Testosterone undecanoate in oral form must be administered with food and in divided doses to maintain stable androgen levels.” — Bagchus et al., European Journal of Endocrinology

This format is favored by those seeking discretion, ease, and flexibility, especially if injection logistics are a barrier.
