What it is

Equipoise / EQ	Usually boldenone undecylenate: a long-acting injectable anabolic steroid discussed for appetite, gradual muscle gain and endurance.
Ester matters	Undecylenate, cypionate and acetate are different forms. Their timing stories cannot be treated as interchangeable.

Notes

Boldenone, usually called Equipoise or EQ, is a long-acting injectable anabolic steroid discussed for appetite, gradual muscle gain and training endurance. The appeal is steady progress without dramatic bloating. Reports also include little benefit, reduced appetite, anxiety and raised blood pressure; its slow exit can make an unwanted experience linger.

Usually boldenone undecylenate in an oil injection. The undecylenate ester is the attached part that makes release slow. The existing record describes intramuscular use, meaning into muscle, and no peptide reconstitution. This is a veterinary-associated steroid, and USADA states it has no FDA-approved human use. USADA: 5 Things Athletes Should Know About Boldenone (Official context · Accessed 2026-09-30)

Bold cyp and bold ace are different ester forms. Forum shorthand can mix cypionate, acetate and undecylenate. Their timing claims should stay separate. Testosterone is a frequent companion, so a stack's changes cannot all be credited to EQ; calling it part of a cruise does not make it testosterone replacement.

What people notice

Muscles and endurance	Some describe fullness, vascularity and gradual gains or better endurance while also using testosterone and other drugs.
Appetite varies	Some report intense hunger. Another struggled to eat and noticed no loss of strength or endurance after dropping EQ.
Mood can worsen	Reports include daytime sleepiness, depression, apathy, anxiety and little benefit.

Notes

Fuller muscles and gradual gains. Users describe vascularity, fullness and steady gains. Testosterone, diet and other drugs complicate comparisons. r/steroids: Compounds — Boldenone (Equipoise/EQ), October 2022 (Community discussion · Accessed 2026-09-30)

More work between rest breaks, sometimes more hunger. A 2019 poster described better endurance without extra hunger. Another described hunger and fuller shoulders. Appetite is therefore a possible experience, not a dependable benefit—and eating more does not necessarily mean gaining more muscle. r/steroids: Compounds — Boldenone Undecylenate, December 2019 (Community discussion · Accessed 2026-09-30)

Hunger can arrive with an unwanted mood change. Feedum_sneedson described hunger at 300 mg/week with daytime sleepiness, depression and apathy. Testosterone co-use changed repeatedly. They interpreted symptoms as low estradiol, or E2, and described prolonged consequences; the account establishes no safe testosterone-to-EQ ratio. r/steroids: Compounds — Boldenone (Equipoise/EQ), October 2022 (Community discussion · Accessed 2026-09-30)

Others get neither hunger nor added performance. RuinJazzlike found EQ underwhelming, struggled to eat while taking it, then became hungrier after dropping EQ while keeping testosterone. Strength and endurance did not fall. This is one person's before-and-after account, with unverified products and no proof of what caused the appetite change. r/steroids: Compounds — Boldenone (EQ, Bold Cyp, Bold Ace), May 2021 (Community discussion · Accessed 2026-09-30)

Lower cruise talk includes 150 mg/week; it remains disputed. A 2022 commenter reported year-round 150 mg/week, with higher blasts. A separate 2021 account reported anxiety without benefit at 200 mg/week for four weeks. Neither establishes a safe maintenance dose. r/steroids: Compounds — Boldenone (Equipoise/EQ), October 2022 (Community discussion · Accessed 2026-09-30) · r/steroids: Compounds — Boldenone (EQ, Bold Cyp, Bold Ace), December 2021 (Community discussion · Accessed 2026-09-30)

Mood, sleep and sexual changes can outweigh appetite. Anxiety, obsessive thoughts, low libido and depressed feelings appear. Their frequency and hormonal cause remain unresolved by symptoms or forum ratios. r/steroids: Compounds — Boldenone (EQ, Bold Cyp, Bold Ace), December 2021 (Community discussion · Accessed 2026-09-30)

Doses people talk about

Undecylenate forum band	300–600 mg/week, with 400–500 mg/week central in the older notes. This is discussion, not a validated regimen.
Lower amounts	150 mg/week appears in a year-round account. A separate 200 mg/week, four-week account reports anxiety without benefit.
High-amount nonresponse	1.5 g/week EQ alongside 1 g/week testosterone brought little added performance in one report; the separate amounts do not support escalation.

Notes

Undecylenate: 300–600 mg per week in the existing community band. The older record centers 400–500 mg/week. A T Nation account describes EQ 450 with testosterone 250 during a 12-week course; that post does not explicitly state the unit or frequency beside those two numbers, so they are not converted into verified weekly totals. T Nation: Equipoise Experience and Results (Community discussion · Accessed 2026-09-30)

A high amount does not guarantee an added benefit. RuinJazzlike reported 1.5 g/week of EQ alongside 1 g/week of testosterone and little added performance. Those are separate weekly totals; 1.5 g equals 1,500 mg. The account does not establish a dose threshold or justify escalation. r/steroids: Compounds — Boldenone (EQ, Bold Cyp, Bold Ace), May 2021 (Community discussion · Accessed 2026-09-30)

Half-life, onset & duration

Felt onset	Older notes describe quiet weeks 1–4 and appetite/fullness in weeks 5–12. One user noticed changes around week seven, with anxiety and high blood pressure.
Felt duration	No dependable single-injection window. Some unwanted symptoms continued weeks after stopping while other hormones were also changed.
Half-life	14 days and up to about 19 days circulate for undecylenate. They are calculator/forum estimates here, not established human measurements or recovery dates.

Notes

Weeks rather than an immediate training boost. Older notes describe quiet weeks 1–4 and appetite/fullness in weeks 5–12. A 2019 user noticed changes around week seven, with anxiety and high blood pressure. These subjective timelines do not promise that waiting longer pays off. r/steroids: Compounds — Boldenone Undecylenate, December 2019 (Community discussion · Accessed 2026-09-30)

No dependable single-injection benefit window. KeminSoro felt normal about two weeks after stopping, yet still described EQ as clearing four weeks afterward. Co-use continued; feeling better does not prove elimination. r/steroids: Compounds — Boldenone (EQ, Bold Cyp, Bold Ace), December 2021 (Community discussion · Accessed 2026-09-30)

Some adverse accounts continue well after stopping. Nobenchrichy described good early endurance, worsening mood after about eight weeks, severe mood, joint and sexual symptoms later, and ongoing difficulties four weeks after stopping. They changed several other hormones while trying to recover, so this cannot define an EQ-only recovery calendar. r/steroids: Compounds — Boldenone Undecylenate, December 2019 (Community discussion · Accessed 2026-09-30)

14 days and up to about 19 days are separate circulated undecylenate estimates. GearCalcs uses 14 days as a simplified calculator input, not measured blood data. An Eroids reply claims up to 19 days for undecylenate and about two weeks for cypionate, without a measurement source. Neither establishes a human value. Half-life means a measured amount falls by half; it is not symptom duration or a drug-test clearance date.

Cycles people discuss

Course talk	12–16 weeks in the older community notes, justified by the slow ester. That does not establish a safe or effective course.
Time off	No agreed break or recovery calendar emerges. Continuing a low amount is still ongoing exposure.

Notes

12–16 weeks in the older community notes. The slow ester is the stated rationale. That does not establish an effective or safe course, and course length is distinct from onset and half-life.

No agreed time-off rule in the inspected accounts. Continuing a low cruise amount or stopping for symptoms does not establish hormone recovery or a safe repeat calendar. r/steroids: Compounds — Boldenone (Equipoise/EQ), October 2022 (Community discussion · Accessed 2026-09-30) · r/steroids: Compounds — Boldenone (EQ, Bold Cyp, Bold Ace), December 2021 (Community discussion · Accessed 2026-09-30)

Stacks

Testosterone	A frequent companion; reported benefits and adverse effects cannot all be assigned to EQ.
Aromatase inhibitors	Some users also report an inhibitor despite low-estradiol stories elsewhere. EQ is not a dependable estrogen-control drug, and no safe ratio follows.

Notes

Testosterone: Appears alongside EQ in the inspected accounts. Repeated changes in either compound prevent a reliable testosterone-to-EQ ratio from being inferred. [community]

Aromatase inhibitors: Some users report additional inhibitor use despite low-E2 stories elsewhere. Symptoms and borrowed ratios do not establish EQ as reliable estrogen control or verify a corrective combination. [community]

EQ is not reliably an estrogen-control drug. The old record includes aromatase-inhibitor co-use when estrogen symptoms remain. Johnyboi98 also reported needing an inhibitor in two EQ courses. That disagreement matters beside low-E2 stories: borrowing someone else's ratio or adding drugs to correct symptoms is not a settled solution. r/steroids: Compounds — Boldenone (Equipoise/EQ), October 2022 (Community discussion · Accessed 2026-09-30)

Watch for

Blood pressure and hematocrit	Both appear in the record. Blood donation did not resolve one user's pressure trouble; it is not an automatic fix.
Mood and hormones	Anxiety, low libido and depressed mood can outweigh perceived benefits. Testosterone suppression and a long unwanted tail remain concerns.
Legal, sport and identity	The record lists U.S. Schedule III status, prohibition in tested sport, no FDA-approved human use and uncertain underground product identity.

Notes

Blood pressure and blood counts are different concerns. Hematocrit is the proportion of blood occupied by red blood cells. The old record's thick-blood and donation talk should not become an automatic fix: an Eroids user reported persistent blood pressure trouble despite donating, without elevated hematocrit at that donation. Their speculation about iron did not establish the cause. Eroids: Your experiences and opinions with Boldenone (Personal report · Accessed 2026-09-30)

Suppression and uncertain human safety remain relevant. USADA warns of decreased testosterone production. Its fertility findings cited here come from animals, not a measured human EQ course. Long-term human safety is not established by reassuring logs or absence of obvious symptoms. USADA: 5 Things Athletes Should Know About Boldenone (Official context · Accessed 2026-09-30)

U.S. Schedule III; tested-sport prohibition and identity risk. The federal schedule lists boldenone as an anabolic steroid. USADA identifies it as prohibited at all times. The existing record also warns that underground product identity is uncertain; a label or a claimed clinic association does not verify contents or authorize use. eCFR: 21 CFR 1308.13, Schedule III (Official context · Accessed 2026-09-30) · USADA: 5 Things Athletes Should Know About Boldenone (Official context · Accessed 2026-09-30)
