What it is

Identity	Stenabolic, an experimental small molecule developed around REV-ERB clock/metabolism signaling; it is different from a peptide or SARM.
Forms differ	Swallowed, sublingual, skin-applied and injectable experiments appear. Disputed oral absorption prevents treating their milligrams as equivalent exposures.

Notes

SR9009, nicknamed Stenabolic, is an experimental small molecule discussed for easier cardio, less morning grogginess and cutting. Reports range from useful energy to no change or disturbed sleep. It is not a peptide or SARM, and the familiar split-dose schedules are community experiments rather than established human protocols.

A clock-and-metabolism research compound. It was developed to activate REV-ERB proteins, which help regulate daily activity and metabolic gene programs. That is why discussion connects endurance with waking and sleep. Cell and mouse findings do not establish an effective human fitness drug. Solt et al. 2012 — REV-ERB agonists and metabolism (Animal context · Accessed 2026-09-30)

The form matters. Discussion mostly concerns swallowed capsules/liquids; under-the-tongue, skin-applied and injectable experiments also appear. Oral absorption is a recurring dispute. Reports from one form cannot establish another form's absorbed dose or effects.

What people notice

Training feels easier	Some describe less breathlessness or later fatigue. A skin-product user reported easier intervals and a 9.8% power-test gain after about a month, possibly helped by sleep.
Wakefulness versus fat loss	One oral user felt readier to start the day but saw little performance or fat-loss benefit alongside Cardarine.
Mixed results	Other accounts describe no benefit, early lethargy, or poorer sleep rather than better conditioning.

Notes

Easier cardio and repeated efforts. Favorable reports describe less breathlessness, later fatigue or more comfortable training. One cyclist using a transdermal product found moderate-intensity intervals easier and reported a 9.8% power-test improvement after about a month; they thought better sleep might explain it. r/sarmssourcetalk — Oral SR9009 (Community discussion · Accessed 2026-09-30) · r/TheLongLived — transdermal SR9009 shift-worker report (Personal report · Accessed 2026-09-30)

Wakefulness can be more noticeable than fat loss. An oral user felt readier to start the day but noticed little performance or fat-loss benefit alongside Cardarine. Other reports describe steadier drive, a leaner look, no benefit or early lethargy. r/sarmssourcetalk — Oral SR9009 (Community discussion · Accessed 2026-09-30)

Energy, fitness and appearance are different outcomes. A Steroid.com log celebrates easier sets while another member reports nearly two weeks with no benefit. Diet, conditioning, sleep and stacked compounds can change alongside the experiment. Absorption skepticism does not erase positive accounts; a positive feeling does not verify the product. Steroid.com — My SR9009 log (Community discussion · Accessed 2026-09-30)

Sleep and uncomfortable sensations. Reports include insomnia, poorer sleep, warmth and increased heart rate. Other accounts add fatigue, headache, dizziness and oral-liquid stomach upset. A transdermal user reported skin irritation; an injectable user described visual disturbance at higher amounts. r/sarmssourcetalk — SR9009 and sleep (Community discussion · Accessed 2026-09-30) · r/sarmssourcetalk — Oral SR9009 (Community discussion · Accessed 2026-09-30) · r/TheLongLived — transdermal SR9009 shift-worker report (Personal report · Accessed 2026-09-30) · AnabolicMinds — Half-life of SR9009 injectable (Community discussion · Accessed 2026-09-30)

Doses people talk about

Split daily reports	Separate replies describe 5 mg four times/day, 20 mg total, and 10 mg three times/day, 30 mg total. The latter also used 10 mg/day Cardarine; form details are incomplete.
Oral chart talk	20–30 mg/day is circulated, alongside lower 5–15 mg and upper 30–40 mg claims; wider charts span 5–50 mg/day. These do not establish an effective dose ladder.
Skin-applied account	35 mg once daily changed to 50 mg/day across three applications; applied amount is different from absorbed or swallowed amount.
Injectable accounts	A planned 15 mg/day split and a retrospective roughly 24 mg/day account remain separate from oral reports.

Notes

Reported totals: 20 or 30 mg per day. Separate replies report 5 mg four times/day (20 mg total) and 10 mg three times/day (30 mg total). The latter used four-hour spacing and 10 mg/day GW-501516. Reply-level form details are incomplete; these amounts do not establish oral absorption. r/sarmssourcetalk — SR9009 In Retrospect (Community discussion · Accessed 2026-09-30) · r/sarmssourcetalk — SR9009 and sleep (Community discussion · Accessed 2026-09-30)

Guide bands are broader than those individual reports. Community charts include 20–30 mg/day oral, lower 10–15 mg/day or 5–10 mg starts, and upper 30–40 mg/day claims, with charts spanning 5–50 mg/day. Two to four administrations and 30–45-minute pre-training timing recur; none is a validated dose ladder.

Skin-applied amounts are separate. A transdermal report changed from 35 mg once/day to 50 mg/day across three applications. Applied milligrams are not absorbed or swallowed amounts. AnabolicMinds — Does SR9009 actually work? (Personal report · Accessed 2026-09-30)

Injectable amounts are separate. A forum contains a planned 15 mg/day split and a retrospective roughly 24 mg/day account. Neither establishes an oral equivalent. AnabolicMinds — Half-life of SR9009 injectable (Community discussion · Accessed 2026-09-30)

Source context — r/sarmssourcetalk — SR9009 In Retrospect: Retrospective recall, deleted author identities, unverified products; OP cannot recall dose; 30 mg reply's route unanswered. Post-treatment activity confounds weight loss.

Source context — AnabolicMinds — Does SR9009 actually work?: Unverified transdermal formulation; only two days on changed schedule and amount; neither absorption nor half-life measured. Cancer-safety inference rejected.

Half-life, onset & duration

Felt onset	Immediate warmth/energy and higher heart rate in one liquid account; another oral report described change after a week.
Felt duration	No reliable single-dose window. Some oral users call effects brief; one skin-product user shifted from energy to sleepiness before changing amount and frequency.
Half-life	Human oral and injectable values remain unknown here. About four hours, or 2–6 hours, is community lore; a cited two-hour figure concerns animal work.

Notes

Immediate energy and one-week changes both appear. The liquid user describes immediate warmth, energy and higher heart rate. A separate oral contributor noticed strength/endurance changes after one week. Others feel nothing. These reports establish no reliable absorption-to-effect timeline. r/sarmssourcetalk — SR9009 and sleep (Community discussion · Accessed 2026-09-30) · r/sarmssourcetalk — Oral SR9009 (Community discussion · Accessed 2026-09-30)

A single-dose window is unclear. Oral contributors say effects are brief without measuring hours. A skin-applied user's energy faded into sleepiness after once-daily application; changed amount and frequency then felt better. These observations cannot establish an all-day coverage schedule. r/sarmssourcetalk — Oral SR9009 (Community discussion · Accessed 2026-09-30) · AnabolicMinds — Does SR9009 actually work? (Personal report · Accessed 2026-09-30)

Roughly four hours is lore, not a human measurement. Community discussion repeats about four hours and a wider 2–6-hour claim. A forum reply gives 4–6 hours without a study of oil-based IM use. Human oral and injectable elimination remain unknown. AnabolicMinds — Half-life of SR9009 injectable (Community discussion · Accessed 2026-09-30)

Injected mice are a different evidence base. Solt's program used 100 mg/kg intraperitoneal SR9009 twice/day for six days in one experiment. A cardiac mouse paper uses 100 mg/kg/day IP and cites a two-hour half-life. These are animal contexts, not human oral values; its benefits also persisted without cardiac REV-ERB, complicating a clock-only explanation.

Cycles people discuss

Circulated blocks	4–10 weeks, often 6–8, sometimes with roughly equal time off. A stacked report describes 1.5 months with weekends off; an injectable guide gives 4 weeks on/2 off.
Longer histories	Three months orally and roughly a year in an injectable account do not establish long-term safety or a useful reset interval.

Notes

Four to ten weeks is a circulated range. Community calendars emphasize 6–8-week blocks, four-week trials and 8–10-week extensions, sometimes with roughly equal time off. A linked stacked report describes 1.5 months with weekends off; a commercially linked injectable user guide describes four weeks on/two off. r/sarmssourcetalk — SR9009 and sleep (Community discussion · Accessed 2026-09-30) · r/BiohackingU — injectable SR9009 user guide (Community guide · Accessed 2026-09-30)

Longer accounts do not establish safety. A retrospective oral account ran three months; an injectable account recalled about a year. Seasonal reruns and continuous-use talk remain community practices. Claims that post-cycle hormone recovery treatment (PCT) is unnecessary rest on SR9009 not being androgen-directed; they do not establish endocrine safety or address suppressive stack partners. r/sarmssourcetalk — SR9009 In Retrospect (Community discussion · Accessed 2026-09-30) · AnabolicMinds — Half-life of SR9009 injectable (Community discussion · Accessed 2026-09-30)

Source context — r/BiohackingU — injectable SR9009 user guide: Commercial purchase link in OP; categorical efficacy/safety claims unsupported. Dosing section says 'cardarine' despite SR9009 title: dose excluded rather than silently repaired. Title says September 2024; publication date not inferred.

Stacks

Cardarine	The prominent conditioning pairing; one 30 mg/day SR9009 reply also reported 10 mg/day GW-501516.
Cut and recovery stacks	Ostarine, MK-677, LGD-4033 or RAD-140 appear in stacks. MK-677 hunger can work against cutting goals.
Other add-ons	Caffeine/fat-burners and BPC-157/TB-500 also appear, making energy, heart-rate sensations and recovery harder to assign to SR9009.

Notes

Cardarine (GW-501516) + SR9009: The top named endurance/conditioning dual stack — GW for session fat-ox / longer coverage, SR for split-dose metabolic/clock narrative. [community]

Stacks make attribution harder. Discussion pairs SR9009 with Cardarine, Ostarine, MK-677, sometimes LGD-4033/RAD-140, stimulants or BPC-157/TB-500. MK-677 hunger can conflict with a cut. SR9011 comparisons and SLU-PP exercise-mimetic talk do not make these interchangeable compounds or establish a superior stack.

Cut SARM stacks: Deficit + Ostarine (MK-2866) ± SR9009 (and often Cardarine) for recomp/cut talk; LGD-4033 or RAD-140 sometimes appear in more aggressive cut/recomp stacks — multiplies unknown risks. [community]

SOCOM / “functional” naming: Vendor and gym culture often groups MK-677 + Cardarine + SR9009 as a sleep/hunger + endurance + metabolic trio (names vary; ratios/vendor bottles vary). [community]

Stim / fat-burner adjacency: Caffeine or commercial fat-burners muddy energy attribution and HR feel. [community]

Peptide recovery add-ons: Some cut stacks add BPC-157/TB-500-class recovery talk while running SR for conditioning — different pathways, confounded logs. [community]

Watch for

Sleep and physical symptoms	Insomnia, warmth, increased heart rate, fatigue, headache, dizziness and oral-liquid stomach upset are reported; skin irritation and higher-amount injectable visual disturbance also appear.
Safety and stack partners	Human long-term and endocrine safety remain unresolved. Calling SR9009 non-androgenic does not address suppressive partners or establish that recovery treatment is unnecessary.
Tested sport	The saved WADA source lists SR9009 as a metabolic modulator prohibited at all times; half-life lore provides no exemption.

Notes

Non-SARM does not mean safe. Long-term human safety, endocrine effects and reliable consumer-product identity remain unresolved. Claims of no suppression, liver clearance or cancer safety exceed the reports. WADA lists SR9009 as a prohibited metabolic modulator at all times; a short half-life is no exemption.

Half-life: repeated estimates

Roughly four hours is lore, not a human measurement. Community discussion repeats about four hours and a wider 2–6-hour claim. A forum reply gives 4–6 hours without a study of oil-based IM use. Human oral and injectable elimination remain unknown. Community AnabolicMinds
Intervals do not prove half-life. Repeated-dose oral routines are justified by lore. Feeling an effect longer, or choosing a repeat-dose interval, does not measure clearance. Community

When people notice it

Immediate energy and one-week changes both appear. The liquid user describes immediate warmth, energy and higher heart rate. A separate oral contributor noticed strength/endurance changes after one week. Others feel nothing. These reports establish no reliable absorption-to-effect timeline. Reddit Reddit
Later checkpoints are community habits. Community discussion describes weeks 1–2 for cardio tolerance and weeks 3–4 for deciding whether anything changed. Pre-cardio timing is a scheduling claim, not proof that SR9009 starts working within 30–45 minutes. Community Community

How long reported effects last

A single-dose window is unclear. Oral contributors say effects are brief without measuring hours. A skin-applied user's energy faded into sleepiness after once-daily application; changed amount and frequency then felt better. These observations cannot establish an all-day coverage schedule. Reddit Personal report
After stopping, activity can change the story. The retrospective oral poster felt less fatigue through a three-month course but little weight loss until becoming more active afterward. Other reports describe fading energy with retained training fitness. Neither proves drug persistence, a washout time or lasting metabolic changes. Reddit Community
