Product Overview
Equipoise 300 mg by Stealth Labs
Equipoise 300 mg is an oil-based injectable containing boldenone undecylenate manufactured by Stealth Labs and dosed at 300 mg/mL in a 10 mL vial.
Boldenone Undecylenate Injectable
Equipoise 300 mg is a long-acting anabolic-androgenic steroid containing boldenone undecylenate, a veterinary-grade compound that has been used in non-medical bodybuilding contexts for decades. Its extended release profile and distinct effects on appetite and endurance distinguish it from testosterone-based preparations.
Boldenone is not approved for human medical use in most countries and is classified as a controlled substance in the United States, United Kingdom, and many other jurisdictions. In bodybuilding and performance-enhancement settings, boldenone undecylenate is commonly referenced as a compound that promotes lean mass gains, increased vascularity, and enhanced endurance, though such use falls outside approved indications.
Boldenone supports nitrogen retention and protein synthesis, contributing to gradual gains in lean body mass. Its erythropoietic effects increase red blood cell production, which can enhance oxygen delivery and endurance but also elevates hematocrit, a primary safety concern. Users should be aware that boldenone undecylenate metabolites remain detectable for approximately 5 months after discontinuation.

Formulation
Oil-Based Injectable
Equipoise 300 mg is presented as an oil-based injectable formulation. The specific carrier oil is not identified in the available product information.
Product Profile
Boldenone Undecylenate Profile
Boldenone undecylenate is a long-acting anabolic ester designed for gradual release after intramuscular administration, with a pharmacokinetic profile that requires extended cycle durations to realize its full effects.
Long-Acting Anabolic Ester
The undecylenate ester slows the release of boldenone from the injection site, producing an extremely long duration of activity. The active half-life is commonly referenced as approximately 14 days, making it one of the longest-acting anabolic esters. This extended release profile means blood levels accumulate gradually, and noticeable effects are typically not observed until weeks 4–6 of use.
Boldenone is structurally a 1-dehydro derivative of testosterone, distinguishing it from 19-nortestosterone derivatives like nandrolone. Once the ester is cleaved, the active hormone is boldenone, which exhibits moderate androgenic activity and aromatizes at a relatively low rate compared to testosterone.
These characteristics explain why boldenone undecylenate is encountered in non-medical bodybuilding settings where longer, well-structured cycles are commonly preferred, and why short cycles of 6–8 weeks are generally considered ineffective with this compound.
Release Profile
Gradual, Extended Boldenone Release
Boldenone undecylenate has an extremely long release profile with an active half-life of approximately 14 days. This contrasts sharply with shorter-acting esters and requires cycle durations of at least 12–14 weeks to realize full effects. After discontinuation, metabolites remain detectable for approximately 5 months, and PCT should not begin until 4–5 weeks after the final injection to allow for ester clearance.
Equipoise 300 mg vs Other Stealth Labs Preparations
Stealth Labs offers several anabolic compounds commonly referenced in bodybuilding contexts. Deca 300 contains nandrolone decanoate, which is commonly associated with joint support and mass gains, while Testosterone Enanthate provides a long-acting testosterone alternative with different estrogenic activity.
The primary distinction between Equipoise 300 mg and these preparations is the active hormone and its effects. Boldenone is noted for appetite stimulation and endurance benefits that are less pronounced with nandrolone or testosterone. However, all three compounds suppress endogenous testosterone production and require careful cycle planning and recovery protocols.

Dosage & Usage
Equipoise 300 mg Dosage & Usage
The information below is provided for educational reference only. Boldenone undecylenate is not approved for human medical use in most countries and is classified as a controlled substance. Non-medical use falls outside approved indications.
Typical Dosage Ranges
In non-medical bodybuilding settings, boldenone undecylenate such as Equipoise 300 mg is commonly referenced in the range of 200–400 mg per week for beginners, with more experienced users referencing 400–600 mg per week. A clinical study in male bodybuilders documented significant increases in fat-free mass with 200 mg per week over 8 weeks. Some sources suggest higher doses up to 600 mg per week, though excessive doses above 800 mg/week increase hematocrit and cardiovascular risks.
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Beginner (non-medical) | 200–400 mg / week | Once or twice weekly |
| Intermediate (non-medical) | 400–600 mg / week | Split twice weekly |
| Stacking base compound | Commonly 1:1 ratio with testosterone | Per cycle protocol |
Stacking & Cycle Considerations
In non-medical bodybuilding contexts, boldenone undecylenate is frequently stacked with testosterone. A common approach is a 1:1 ratio, such as 300 mg Testosterone and 300 mg Equipoise per week, to help maintain healthy estrogen levels since boldenone can act as an aromatase inhibitor for some users. Stealth Labs offers Testosterone Enanthate or Testosterone Cypionate as base compounds.
Because of the extremely long undecylenate ester, boldenone cycles are typically referenced as lasting 12–16 weeks minimum, with some sources recommending 14 weeks as ideal. Short cycles of 6–8 weeks are generally considered ineffective because blood levels have not yet reached steady state. Cycle structure and duration should be considered carefully given the prolonged detection window of approximately 5 months.
Managing Side Effects
The most clinically significant side effect of boldenone is increased hematocrit and red blood cell count, which is more pronounced than with most other anabolic steroids. Elevated hematocrit can increase blood viscosity and cardiovascular strain. Monitoring hematocrit and RBC levels is essential, with the first check recommended around week 6–8.
Boldenone is associated with anxiety and restlessness at higher doses, sometimes referred to as “EQ anxiety”. Increased appetite is another commonly reported effect that can be beneficial for mass-building but problematic for cutting goals. Aromatase inhibitors such as Arimidex may be referenced for managing estrogen-related effects, though boldenone aromatizes at a relatively low rate.
Post-Cycle Therapy (PCT)
After completing a cycle with Equipoise 300 mg, post-cycle therapy is commonly recommended in non-medical contexts to help restore endogenous testosterone production. Because of the long undecylenate ester, PCT should not begin until 4–5 weeks after the final injection to allow for ester clearance. Agents such as Clomid or Tamoxifen are commonly referenced for this purpose.
PCT protocols vary based on cycle length, compounds used and individual factors. A typical protocol referenced in bodybuilding contexts includes Clomid at 50 mg/day for 4 weeks and Nolvadex at 20 mg/day for 4–5 weeks. Bloodwork and, where possible, medical guidance can help inform recovery strategy.

Individual Response Varies
Dosing strategies, support compounds and recovery protocols should be adjusted based on experience level and bloodwork where possible. The information above is for educational reference and does not constitute medical advice.
Safety & Information
Boldenone Undecylenate Safety Information
Boldenone undecylenate is not approved for human medical use in most countries and is classified as a controlled substance. It can affect hematologic, cardiovascular, and endocrine function. Non-medical use carries significant health risks.
Important Safety Information
Boldenone undecylenate is a veterinary anabolic steroid that is not approved for human use. The FDA has not approved boldenone for any human medical indication. In the United States and many other countries, it is classified as a controlled substance.
Anabolic steroids suppress the body’s own testosterone production and can affect fertility and endogenous hormone balance. Boldenone has been associated with significant hematologic changes that require monitoring.
Important
Non-Medical Use
Higher-than-physiologic exposure to anabolic steroids can carry additional health risks. Product concentration and laboratory verification do not establish that non-medical use is safe or appropriate for an individual. Boldenone is not approved for human use, and obtaining it without a prescription is illegal.
Potential Adverse Effects
The primary and most clinically significant side effect of boldenone is increased hematocrit and red blood cell count, which is more pronounced than with most other anabolic steroids. Elevated hematocrit increases blood viscosity and can lead to hypertension, headaches, dizziness, and increased cardiovascular risk. Cases of stroke and deep vein thrombosis have been reported in association with anabolic steroid use.
Boldenone is associated with anxiety and restlessness, particularly at higher doses or in anxiety-prone individuals. Increased appetite is a commonly reported effect. Other potential effects include acne, oily skin, mild hair thinning in genetically predisposed individuals, and suppression of endogenous testosterone production.
Blood lipid changes associated with increased atherosclerosis risk are seen with anabolic steroid use, including decreased high-density lipoprotein and sometimes increased low-density lipoprotein.
Conditions Requiring Medical Evaluation
Boldenone use is contraindicated in individuals with polycythemia or elevated hematocrit above 50% at baseline, cardiovascular disease or history of thromboembolic events, hepatic impairment, and pre-existing anxiety disorders.
Existing cardiovascular disease, abnormal blood counts, and other medical conditions should be discussed with a qualified healthcare professional before any consideration of use.
Monitoring During Use
Hematocrit and red blood cell count should be monitored regularly during boldenone use, with the first check recommended around week 6–8. Blood pressure, lipid profile, and liver function should also be assessed periodically.
Laboratory testing of the product itself is separate from clinical monitoring of the person using the product. Product testing does not assess individual health status or suitability for use.

Frequently Asked Questions
Equipoise 300 mg FAQ
Answers to common questions about Equipoise 300 mg, boldenone undecylenate, release characteristics, product strength and laboratory testing.
What is Equipoise 300 mg used for?
Equipoise 300 mg contains boldenone undecylenate, which is not approved for human medical use in most countries. In non-medical bodybuilding settings it is commonly referenced for lean mass gains, increased vascularity, and enhanced endurance, though such use falls outside approved indications and carries significant health risks.
How often should Equipoise 300 mg be injected?
Because of its extremely long-acting undecylenate ester with a half-life of approximately 14 days, Equipoise 300 mg is typically referenced as being administered once weekly or split into two injections per week. More frequent administration is not necessary due to the slow release profile.
Does Equipoise 300 mg require PCT?
In non-medical bodybuilding contexts, post-cycle therapy is commonly recommended after a boldenone cycle to help restore endogenous testosterone production. Because of the long undecylenate ester, PCT should not begin until 4–5 weeks after the final injection to allow for ester clearance. Agents such as Clomid or Tamoxifen are commonly referenced for this purpose.
What does boldenone undecylenate do?
Boldenone undecylenate is a long-acting anabolic ester. After administration, the esterified compound is released gradually and provides active boldenone, which supports nitrogen retention and protein synthesis. Boldenone also has erythropoietic effects that increase red blood cell production, which can enhance oxygen delivery but also elevates hematocrit.
How long does boldenone undecylenate take to work?
Boldenone undecylenate has an extremely slow onset due to its very long undecylenate ester. Minimal noticeable effects are typically reported during weeks 1–3, with blood levels still accumulating. Early improvements in recovery and endurance may begin around weeks 4–6, with visible changes in body composition appearing between weeks 8–12.
Is boldenone the best anabolic?
There is no single anabolic agent that is universally best. Boldenone has a distinct profile compared to testosterone and other compounds, with a long release profile, moderate estrogenic activity, and notable effects on appetite and endurance. The appropriate choice depends on the circumstances and individual factors, and non-medical use falls outside approved indications.
What is the difference between Equipoise 300 mg and Deca 300?
Deca 300 contains nandrolone decanoate, a 19-nortestosterone derivative, while Equipoise 300 mg contains boldenone undecylenate, a 1-dehydro derivative of testosterone. Nandrolone is commonly associated with joint support and mass gains, while boldenone is noted for appetite stimulation and endurance benefits. Both suppress endogenous testosterone production.
What is the difference between Equipoise 300 mg and Testosterone Enanthate?
Boldenone undecylenate and testosterone enanthate are different active substances with distinct pharmacological profiles. Boldenone aromatizes at a much lower rate than testosterone and has a longer active half-life. Testosterone Enanthate provides a long-acting testosterone alternative with different estrogenic activity and side effect considerations.
Is 300 mg of Equipoise a lot?
A milligram amount cannot be classified as appropriate or excessive without considering the medical indication, individual response, and other factors. It is also important to distinguish a dose in milligrams from a product’s concentration in mg/mL. Equipoise 300 mg is labeled at 300 mg/mL; that concentration does not by itself specify how much should be administered.
What strength is Equipoise 300 mg?
Equipoise 300 mg is labeled at 300 mg of boldenone undecylenate per mL. It is supplied in a 10 mL vial, giving 3,000 mg of total labeled boldenone undecylenate content per vial.
Is Equipoise 300 mg lab tested?
Yes. A published laboratory report dated August 23, 2024 measured Equipoise 300 mg at 299.84 mg, equivalent to 99.95% of its 300 mg/mL label claim. The complete report can be viewed in the Lab Reports tab. Laboratory results apply to the tested sample represented by the individual report.
Can Equipoise 300 mg be stacked with other compounds?
In non-medical bodybuilding contexts, boldenone undecylenate is commonly stacked with testosterone, often at a 1:1 ratio to help maintain healthy estrogen levels. Stealth Labs offers Testosterone Enanthate or Testosterone Cypionate as base compounds. Stacking decisions should consider individual experience and health status.
