Boldenone (Equipoise) Dosage & Cycle Guide: Beginner to Advanced (2026)

Boldenone undecylenate (Equipoise) is a long-ester compound that requires a different planning approach than shorter-acting injectables. Its 14-day half-life means cycles must run long enough for the compound to reach stable blood levels — short cycles are genuinely wasteful. This guide covers dosing, cycle structures, the haematocrit management protocol that boldenone makes mandatory, and its optimal stacking partners.

Boldenone Dosage Reference Table

Experience Level	Weekly Dose	Minimum Cycle Length	Notes
Beginner (first EQ cycle)	300–400 mg/wk	14–16 weeks	Always run with testosterone base
Intermediate	400–600 mg/wk	16 weeks	AI required at upper end of range
Advanced	600–1000 mg/wk	16–20 weeks	Haematocrit monitoring critical; AI essential

Injection frequency: Weekly injection of the full dose is possible given the 14-day half-life. Twice-weekly (splitting the dose) produces slightly more stable blood levels and is preferable for doses above 400 mg/week.

Beginner Boldenone Cycle

Week	Testosterone Enanthate	Boldenone	AI	Monitoring
1–16	500 mg/wk	400 mg/wk	Aromasin 12.5 mg EOD	Haematocrit at wk 4, 8, 12
PCT (wk 19–23)	Stop at wk 16	Stop at wk 16	Nolvadex 40/40/20/20	Wait 3 weeks after last injection before PCT

Why wait 3 weeks for PCT? The 14-day half-life of boldenone means significant circulating hormone remains for 3+ weeks after the last injection. Starting PCT too early is ineffective. See our complete PCT guide for timing details.

Intermediate Lean Bulk Cycle

Week	Testosterone Enanthate	Boldenone	Dianabol (Kickstart)	Support
1–6	600 mg/wk	500 mg/wk	40–50 mg/day	TUDCA 500 mg/day; Aromasin 12.5–25 mg EOD
7–18	600 mg/wk	500 mg/wk	Discontinue	Aromasin EOD; haematocrit monitoring

Dianabol is used as a kickstart to produce gains during the 4–6 weeks while boldenone is building to stable blood levels. See our Dianabol complete guide for dosing. Liver support is required for the oral kickstart phase.

Haematocrit Management Protocol

This is the most important safety protocol specific to boldenone. The compound's pronounced erythropoietic effect means haematocrit must be actively monitored:

• Baseline haematocrit: Blood test before starting the cycle
• Week 4 recheck: First on-cycle haematocrit measurement
• Week 8 and 12 rechecks: Continue monitoring throughout
• Target: Keep haematocrit below 52%
• Action at 52–54%: Dose reduction; increase hydration; reduce aerobic training volume
• Action at >54%: Consider therapeutic phlebotomy (blood donation is the simplest approach — donating 450–500 ml removes approximately 200–250 mg of haemoglobin and reduces haematocrit by 3–4 percentage points). Consult a GP.

For comprehensive blood monitoring guidance, see our evidence-based harm reduction guide.

Oestrogen Management

Boldenone aromatises at approximately 50% the rate of testosterone, but when combined with a testosterone base at 500–600 mg/week, total oestrogen load remains significant. An aromatase inhibitor is required at intermediate and advanced doses. Arimidex or Aromasin are appropriate — see our AI products.

Post Cycle Therapy

The long half-life of boldenone requires careful PCT timing. As a general rule:

• If running boldenone solo (no testosterone): wait 3 weeks after last injection before starting PCT
• If running boldenone with testosterone enanthate: the testosterone ester determines PCT timing — 2 weeks after last testosterone injection, at which point boldenone levels will still be declining but low enough for HPG recovery to begin

Standard PCT: Nolvadex 40/40/20/20 mg over 4 weeks. See our PCT guide for full protocol.

Frequently Asked Questions

Can you run boldenone without testosterone?

Technically yes, but not recommended. All anabolic steroids suppress endogenous testosterone production. Without a testosterone base, users on boldenone-only cycles rapidly develop low testosterone symptoms (low libido, erectile dysfunction, fatigue, mood disturbance). Testosterone at a minimum TRT dose (100–150 mg/week) should always be included.

Does boldenone need to be front-loaded?

Front-loading — doubling the first week's dose to rapidly achieve stable blood levels — is sometimes used with boldenone to reduce the lag time before full effects are felt. A first-week dose of 600–800 mg (when running 400 mg/week) accelerates time to stable levels from 6 weeks to approximately 3 weeks. This approach increases early side effect risk and is not recommended for first-time EQ users. The oral kickstart approach (Dianabol weeks 1–6) achieves a similar practical result with less blood level disruption.

Is boldenone good for cutting?

Yes. Boldenone's low water retention, vascularity enhancement, and lean mass preservation make it suitable for cutting cycles. Its appetite-stimulating property can be counterproductive when trying to maintain a deficit, however. Users who respond with extreme appetite increase may find boldenone harder to manage during a cut than during a bulk.
