Anavar vs Turinabol: Anabolic Ratios, Liver Impact, Detection Windows, and Which One Fits Your Goal
The Anavar vs Turinabol comparison is one of the most common questions in oral steroid selection, and one of the most poorly answered. Both are non-aromatising 17-alpha-alkylated orals. Both are considered “mild” relative to compounds like Dianabol or Anadrol. Both are used for lean gains without water retention. On paper, they look interchangeable. In reality, they differ in almost every pharmacological dimension that matters: their anabolic-to-androgenic ratios are structured differently, their half-lives shape different dosing requirements, their liver impact is not equivalent, their detection windows are dramatically different, and the quality of human clinical data behind each compound is not even close. At Hemi Pharma UK, this article walks through every meaningful difference so you can choose based on pharmacology, not reputation.
How Do the Anabolic-to-Androgenic Ratios Compare in the Anavar vs Turinabol Debate?
The anabolic-to-androgenic ratio is the single number that most people look at first when comparing steroids, and in the Anavar vs Turinabol comparison it reveals an important structural difference between the two compounds.
Oxandrolone (Anavar) has an anabolic rating of 322 and an androgenic rating of 24, relative to methyltestosterone as the reference standard. This gives a ratio of approximately 13:1. In plain terms, for every unit of masculinising effect, oxandrolone produces 13 units of muscle-building effect. This extreme separation is why Anavar is the preferred oral steroid for women: it produces meaningful anabolic results with proportionally very little androgenic activity.
Chlorodehydromethyltestosterone (Turinabol) has an anabolic rating of 54 and an androgenic rating of 6, giving a ratio of approximately 9:1. The ratio is favourable (better than testosterone’s 1:1), but the absolute numbers are much lower than Anavar’s. An anabolic rating of 54 means Turinabol produces roughly one-sixth the anabolic potency of oxandrolone per milligram. An androgenic rating of 6 means Turinabol is less androgenic per milligram than Anavar, but because you need much higher doses to achieve equivalent anabolic effects, the total androgenic exposure at equivalent effective doses may not be dramatically different.
What this means practically in the Anavar vs Turinabol comparison: milligram for milligram, oxandrolone is a substantially more potent anabolic agent. A user taking 40mg of Anavar per day is receiving a much stronger anabolic signal than a user taking 40mg of Turinabol per day. To achieve approximately equivalent anabolic stimulation, Turinabol doses typically need to be 50 to 80mg per day, while Anavar achieves its clinical optimum at 40mg per day (as demonstrated in the Grunfeld dose-comparison trial). This dose differential has consequences for liver stress, cost, and total side-effect burden.
Which Compound Is Harder on Your Liver in the Anavar vs Turinabol Comparison?
Both oxandrolone and chlorodehydromethyltestosterone are 17-alpha-alkylated, meaning both carry the structural modification that makes them orally bioavailable but also hepatotoxic. However, their liver impact is not equal.
Oxandrolone has a unique chemical structure (the C-2 lactone ring and absent A-ring 4-ene function) that makes it remarkably resistant to hepatic metabolism. 28% of each dose is excreted completely unchanged in the urine. Because the liver does not have to work as hard to process oxandrolone, the oxidative stress per dose is lower than with other 17-alpha-alkylated steroids. Clinical data from burn patients showed a 42.4% incidence of transaminitis during oxandrolone therapy at 20mg per day, but clinically dangerous elevations (greater than 5 times the upper limit of normal) were rare.
Turinabol undergoes significantly more extensive hepatic metabolism. It is a derivative of metandienone (Dianabol) with an added chlorine atom at the C-4 position. While the chlorine prevents aromatisation and the 1,2-double bond reduces androgenic potency, neither modification reduces hepatic first-pass metabolism in the way that oxandrolone’s lactone ring does. The 2026 comprehensive review by Youssef et al. noted that turinabol “undergoes significant first-pass metabolism, resulting in a moderate systemic bioavailability” and that “careful monitoring is necessary due to the risk of liver toxicity, especially with long-term use” (Youssef et al., 2026, Turinabol Comprehensive Review).
In practical terms: at equivalent effective doses (40mg Anavar vs 60mg Turinabol), Turinabol is harder on the liver because each milligram undergoes more hepatic processing, and you need more milligrams to achieve a comparable anabolic effect. This is one of the clearest advantages in the Anavar vs Turinabol comparison for users concerned about hepatotoxicity. If you are stacking either oral with other liver-stressing compounds (alcohol, paracetamol, or other oral steroids), Anavar provides the lower hepatic burden per unit of anabolic effect.
How Do the Half-Lives Differ and What Does That Mean for Dosing?
Oxandrolone has an elimination half-life of 9 to 10.4 hours (13.3 hours in elderly subjects). This means twice-daily dosing is required to maintain stable blood levels: take your daily dose split into two equal portions approximately 12 hours apart.
Turinabol has an elimination half-life of approximately 16 hours. This longer half-life means that once-daily dosing is pharmacokinetically viable: a single morning dose maintains therapeutic blood levels throughout the day and overnight, with less peak-to-trough fluctuation than oxandrolone would produce from a single dose. However, many Turinabol users still prefer splitting the dose twice daily for even more stable levels, which is equally valid given the 16-hour half-life.
In the Anavar vs Turinabol comparison, the practical convenience difference is modest. Turinabol allows once-daily dosing without significant blood-level troughs; Anavar requires twice-daily dosing for optimal stability. Neither schedule is onerous, but if dosing simplicity is a priority, Turinabol has a slight edge.
The half-life difference also affects PCT timing. Oxandrolone clears from plasma within 48 to 72 hours of the last dose (five half-lives of approximately 50 hours). Turinabol takes approximately 80 hours (five half-lives of 16 hours). Neither delay is clinically meaningful; both are effectively cleared within 3 to 4 days.
How Do the Detection Windows Compare, and Why Is This a Massive Difference?
This is the single largest practical difference in the Anavar vs Turinabol comparison, and for any athlete subject to drug testing, it is the deciding factor.
Oxandrolone’s long-term metabolites (identified by Guddat et al., 2013) are detectable for up to 18 to 21 days after the last dose using current WADA-accredited methods. This is a meaningful detection window, but it is manageable for athletes who plan their cycles to allow sufficient clearance before competition testing.
Turinabol’s detection window is in an entirely different category. In 2011 and 2012, Sobolevsky and Rodchenkov identified new long-term metabolites of DHCMT (referred to as M1, M2, M3, and M4) that dramatically extended detection times. The M4 metabolite in particular has been detected 40 to 50 days after a single 5mg dose in a controlled administration trial. Some anti-doping researchers estimate the detection window extends to 6 months or longer with repeated dosing at typical bodybuilding doses. These long-term metabolites were the basis for retrospective retesting of the 2008 Beijing and 2012 London Olympic Games samples, which resulted in numerous retrospective positive findings and medal redistributions (Controlled DHCMT Administration Trial, 2021, J Steroid Biochem Mol Biol).
The practical consequence is severe. An athlete who uses Turinabol and stops 30 days before a competition can still test positive. An athlete whose samples are stored and retested years later (as WADA now does with Olympic samples) can be caught from use that occurred months or even years before the test. The detection window for Turinabol is approximately 2 to 10 times longer than for oxandrolone depending on the dose and duration of use.
Even for non-competing users who are not subject to anti-doping testing, the detection window difference in the Anavar vs Turinabol comparison tells you something about how long the compound and its metabolites persist in your body. Longer metabolite persistence means longer exposure of your organs (particularly the liver and kidneys) to breakdown products.
Which Compound Has Better Clinical Evidence Behind It?
This is where the Anavar vs Turinabol comparison becomes lopsided. Oxandrolone has one of the most extensive human clinical trial databases of any anabolic steroid. The Schroeder RCTs provided DEXA and MRI-measured body composition data. The Grunfeld trial provided the only head-to-head dose comparison (20mg vs 40mg vs 80mg) in 262 men. The Sheffield-Moore studies provided molecular-level protein synthesis data. The Turner syndrome trials provided dose-response virilisation data in females. The burn patient meta-analyses covered thousands of patients. Oxandrolone’s pharmacokinetics, dose-response, body composition effects, strength effects, side effect profile, and recovery kinetics are all documented in peer-reviewed, controlled clinical trials.
Turinabol has almost no modern clinical trial data. The compound was developed in the 1960s by Jenapharm in East Germany and was used extensively in the state-sponsored doping programme from 1968 to 1989 (administered to approximately 10,000 athletes). The clinical studies that do exist are from the 1950s through 1970s, predominantly published in German-language journals, and many were conducted within the East German sports medicine system, which operated under political directives rather than independent scientific oversight. The 2026 Youssef comprehensive review identified 25 experimental studies and 23 clinical trials, but noted that most were from this historical period and would not meet modern standards for randomised, blinded, placebo-controlled trial design.
What this means for your decision: when you use oxandrolone, you can predict your results with reasonable confidence because the dose-response relationship, the body composition effects, the strength gains, and the side-effect profile are all characterised in modern, well-designed trials. When you use turinabol, you are relying primarily on anecdotal user reports and historical data that lacks the methodological rigour of modern clinical evidence. In the Anavar vs Turinabol comparison on evidence quality, Anavar wins overwhelmingly.
Which Compound Is Better for Cutting?
For cutting specifically, the Anavar vs Turinabol comparison favours oxandrolone based on the available evidence.
Oxandrolone has demonstrated fat reduction (1.8 kg total, including 20.9 cm² visceral fat by MRI) in the Schroeder RCT at 20mg per day without dietary restriction. It has demonstrated enhanced nitrogen retention and 44% increased muscle protein synthesis in the Sheffield-Moore data. The fat lost during oxandrolone treatment is 83% sustained 12 weeks after stopping. These body recomposition effects are precisely what a cutting phase aims to achieve: lose fat, keep muscle, maintain a dry appearance.
Turinabol produces lean gains without water retention (because it does not aromatise, similar to Anavar), and its lower androgenic potency means less acne and less hair loss risk. However, there are no modern clinical trials measuring turinabol’s effects on fat mass, visceral fat, or fat-free mass using DEXA or MRI. User reports suggest turinabol provides moderate lean mass gains and strength increases, but the magnitude of these effects relative to oxandrolone at equivalent doses is not characterised in controlled data.
Turinabol’s one potential advantage for cutting is its longer half-life (16 hours), which produces more stable blood levels from once-daily dosing. Stable blood levels mean more consistent anabolic signalling, which may translate to marginally better muscle retention during sleep. However, this advantage is easily matched by simply splitting oxandrolone into twice-daily doses, which achieves equivalent or better blood-level stability.
For women cutting, the Anavar vs Turinabol comparison favours Anavar decisively. Oxandrolone has the Turner syndrome virilisation threshold data and decades of clinical use in females. Turinabol was historically used in women (East Germany’s doping programme administered it to female athletes, often without their informed consent), and the virilising consequences of that programme, including permanent voice changes and other irreversible effects documented in subsequent investigations, serve as a cautionary example rather than an endorsement.
Which Compound Is Better for Lean Bulking?
For slow, lean muscle gain without water retention, the Anavar vs Turinabol comparison is closer. Turinabol’s lower per-milligram androgenic activity and longer half-life make it a reasonable choice for users who want steady, gradual gains over 6 to 8 weeks without the dramatic strength spikes and metabolic shifts that higher-potency compounds produce.
However, oxandrolone’s superior anabolic potency per milligram means that at equivalent effective doses, Anavar provides a stronger growth signal. The Grunfeld trial showed that 40mg of oxandrolone produced 2.8 kg of weight gain in 12 weeks. No equivalent trial exists for turinabol at any dose.
The practical advantage of turinabol for lean bulking is cost. Oxandrolone raw material is significantly more expensive than DHCMT, which means that at the higher doses turinabol requires for equivalent effect (50 to 80mg per day vs oxandrolone’s 40mg), the total cycle cost may still be lower with turinabol. However, this cost advantage only applies to genuine turinabol; given the prevalence of counterfeiting across the oral steroid market, cheaper price does not guarantee cheaper product.
What About SHBG Suppression in the Anavar vs Turinabol Comparison?
Both compounds suppress SHBG, but Anavar is one of the most potent SHBG suppressors of any oral steroid (85% reduction documented in clinical data). Turinabol also binds to and suppresses SHBG, and the 2026 Youssef review noted that turinabol’s “interaction with sex hormone-binding globulin increases free testosterone levels, contributing to its anabolic effects.” However, the magnitude of turinabol’s SHBG suppression has not been precisely quantified in a clinical trial the way oxandrolone’s has.
If you are stacking either oral with injectable testosterone (testosterone cypionate or testosterone enanthate), the SHBG suppression from Anavar provides a known, quantifiable amplification of your free testosterone. With turinabol, the amplification likely exists but its magnitude is less predictable because the clinical data is not there.
Which Compound Should You Choose?
Based on the full Anavar vs Turinabol comparison above, the decision framework is as follows.
Choose Anavar if you want the most clinically validated oral steroid with predictable dose-response, superior milligram-for-milligram anabolic potency, lower hepatotoxicity per unit of anabolic effect, a shorter detection window (18 to 21 days vs 40 to 50+ days), documented fat-reducing and repartitioning effects, the best-characterised female safety profile, or the most potent SHBG suppression for stacking with testosterone.
Choose Turinabol if your primary concern is the lowest possible androgenic side effects per dose (androgenic rating of 6 vs Anavar’s 24), you prefer once-daily dosing convenience, you are looking for a budget-conscious oral for lean gains (provided you can verify it is genuine DHCMT), or you want a very mild entry point for a first oral cycle and are willing to accept the trade-off of less clinical evidence behind your dosing decisions.

Frequently Asked Questions
Is Anavar stronger than Turinabol?
Yes, milligram for milligram. Oxandrolone has an anabolic rating of 322 vs turinabol’s 54. At equal doses (40mg per day of each), Anavar produces a substantially stronger anabolic signal. To match the anabolic effect of 40mg of Anavar, you would need approximately 50 to 80mg of Turinabol, which increases total drug exposure, liver stress, and cost. The Grunfeld RCT confirmed that 40mg of oxandrolone produces statistically significant body composition changes; no equivalent trial exists for turinabol at any dose.
Which is safer, Anavar or Turinabol?
Anavar is less hepatotoxic per milligram because of its unique chemical structure (28% of each dose is excreted completely unchanged). At equivalent effective doses, Anavar produces less liver enzyme elevation. Both compounds suppress testosterone and HDL cholesterol. Turinabol has a lower androgenic rating (6 vs 24), which means theoretically less risk of hair loss and acne, though the higher doses required partially offset this advantage. Overall, Anavar has a better-characterised safety profile because of its extensive modern clinical trial database.
Can women use Turinabol instead of Anavar?
Turinabol was historically administered to female athletes in East Germany’s doping programme, often at doses that produced permanent virilisation. While lower doses (5 to 10mg) are sometimes used by women today, there is no modern clinical trial data establishing virilisation thresholds for turinabol in females. Anavar has the Turner syndrome dose-response virilisation data (16% at 0.03mg/kg, 42% at 0.06mg/kg over years of use) that allows women to make informed dosing decisions. For women, the Anavar vs Turinabol comparison strongly favours Anavar on the basis of evidence quality and characterised safety margins.
Does Turinabol cause water retention?
No. Like oxandrolone, turinabol does not aromatise to oestrogen because the 4-chloro substitution and 1,2-double bond prevent A-ring aromatisation. Both compounds produce dry, non-bloated gains. This is one of the similarities, not differences, in the Anavar vs Turinabol comparison.
How long is Turinabol detectable compared to Anavar?
Dramatically longer. Anavar’s long-term metabolites are detectable for 18 to 21 days after the last dose. Turinabol’s M4 metabolite has been detected 40 to 50 days after a single 5mg dose, and some researchers estimate detection windows of up to 6 months with repeated dosing. These long-term turinabol metabolites led to retrospective positive findings when 2008 and 2012 Olympic samples were retested. For any athlete subject to testing, this detection window difference makes turinabol a far higher-risk choice.
Can I stack Anavar and Turinabol together?
This is not recommended. Both are 17-alpha-alkylated oral steroids that stress the liver through the same mechanism. Stacking two orals compounds hepatotoxicity without providing the complementary-pathway benefit that stacking an oral with an injectable provides. If you want more anabolic effect than Anavar alone, add an injectable like testosterone enanthate or nandrolone decanoate rather than doubling up on oral liver stress.
