Testolone 10mg/tab 60 Tabletten by Elbrus Pharmaceuticals

5 (2 reviews)

Testolone (RAD-140) is a non-steroidal selective androgen receptor modulator from Elbrus Pharmaceuticals, formulated at 10mg per tablet to deliver the highest published anabolic-to-androgenic ratio among characterised SARMs — a distinction that places precise dosing at the centre of responsible use. Skeletal muscle and bone androgen receptors are activated selectively, supporting lean mass accumulation without estrogenic conversion or the hepatotoxic burden associated with 17-alpha-alkylated oral compounds. Each production batch clears two independent analytical gates — finished-product HPLC potency confirmation and LAL endotoxin screening — before any tablets are authorised for distribution.

  • Delivers the highest anabolic-to-androgenic ratio among characterised SARMs — approximately 90:1 in preclinical research.
  • Drives lean muscle accumulation through full AR agonism in skeletal muscle, without concurrent androgenic tissue stimulation.
  • Supports bone density alongside muscle growth via selective androgen receptor activation in osseous tissue.
  • 10mg tablet format enables precise, incremental dose titration from entry level through experienced protocols.
  • No estrogenic conversion pathway — no aromatase activity, no gynecomastia risk from RAD-140 itself.
  • Each batch HPLC-tested at finished-product stage and LAL endotoxin-screened before distribution clearance.
  • 60-tablet pack supports a structured 6-week cycle at standard doses without mid-cycle restocking.

Key takeaways

  • Prioritise the 10mg starting dose to gauge individual RAD-140 tolerance first.
  • Expect the highest anabolic-to-androgenic ratio available in the SARM class.
  • Cap cycles at eight weeks to control testosterone suppression depth.
  • Plan a SERM-based PCT before beginning any RAD-140 mass protocol.
  • Verify HPLC batch documentation — potency accuracy matters at 10mg precision.

RAD-140: The Highest Anabolic Potency Ratio in the SARM Class

Testolone (RAD-140) is defined in pharmacological literature as a full agonist at the androgen receptor in muscle tissue, with an anabolic-to-androgenic ratio measured in preclinical models at approximately 90:1 — the highest published ratio among all characterised SARMs. That figure, documented in research by Radius Health (the original RAD-140 developer), explains why RAD-140 produces measurable lean mass gains at doses where other SARMs remain largely preparatory. Compared to Ostarine (MK-2866), which operates at a ratio closer to 3:1, RAD-140 delivers substantially greater anabolic stimulus per milligram — a meaningful distinction when selecting a compound for a structured mass phase.

RAD-140 activates androgen receptors selectively in skeletal muscle and bone, triggering nitrogen retention, protein synthesis upregulation, and IGF-1 pathway stimulation without the concurrent androgenic signalling that causes scalp, skin, and prostate effects associated with testosterone. The compound also demonstrates neuroprotective properties in preclinical models (published in Endocrinology, 2010), though these remain outside the primary scope of bodybuilding use.

Potency Management: Why 10mg Matters as a Starting Point

The 10mg per tablet format from Elbrus Pharmaceuticals is not simply a packaging choice — it is the clinically relevant entry dose that corresponds to meaningful anabolic activity while allowing users to assess individual response before escalating. Most documented RAD-140 protocols in the bodybuilding community begin at 10mg per day for the first two weeks, with some intermediate users progressing to 15–20mg based on tolerance. The 10mg tablet format enables precise, incremental titration without the need to split tablets or estimate liquid measurements.

Elbrus Pharmaceuticals subjects each RAD-140 batch to HPLC (high-performance liquid chromatography) analysis, confirming that every tablet contains the declared 10mg of active RAD-140 within specification tolerances. LAL (Limulus Amebocyte Lysate) endotoxin testing is applied independently to confirm microbiological safety. Both results are batch-documented and traceable.

Cycle Structure and PCT Obligations

RAD-140 suppresses endogenous testosterone production in a dose- and duration-dependent manner — a biological consequence of its potent AR agonism in the hypothalamic-pituitary axis. Cycle lengths are typically capped at 8 weeks to limit suppression depth, and post-cycle therapy (PCT) using a SERM such as Nolvadex (tamoxifen) or Clomid (clomiphene) is recommended for most users running full mass-phase protocols at or above 15mg per day.

Usage

  1. Complete pre-cycle blood work covering total testosterone, LH, FSH, and a liver panel — this is the benchmark for your PCT recovery assessment.
  2. Begin at exactly one tablet (10mg) per day, taken in the morning with food to reduce the chance of nausea during the assessment phase.
  3. After 14 days at 10mg, evaluate your response — sleep quality, strength trajectory, and any aggression or mood changes — before deciding whether to advance to 15mg.
  4. For mass-phase escalation, take 1.5 to 2 tablets (15–20mg) each morning; do not split the dose across morning and evening, as RAD-140's half-life of approximately 16–20 hours supports once-daily administration.
  5. Do not exceed 8 weeks of continuous use; longer cycles increase suppression depth without proportionate additional anabolic benefit.
  6. Begin SERM-based PCT within 48–72 hours of your final RAD-140 tablet, and repeat blood work four weeks into PCT to confirm testosterone recovery before planning any subsequent cycle.

Warnings

Contraindications: RAD-140 is not suitable for individuals under 21 years of age, women of childbearing potential, or anyone with a diagnosed androgen-sensitive condition including prostate enlargement or hormone-receptor-positive cancer history. Persons with pre-existing cardiovascular disease, lipid disorders, or hepatic impairment should not use RAD-140 without specialist medical clearance.

Side Effects: The most clinically significant effect is suppression of endogenous testosterone production, which is dose- and duration-dependent. Additional reported effects include elevated haematocrit, HDL cholesterol reduction, increased aggression or mood instability, sleep disturbance, and — in genetically predisposed individuals — acceleration of androgenic alopecia. RAD-140 does not aromatise, so oestrogen-related effects originate from the hormonal suppression context rather than direct conversion.

Monitoring: Pre-cycle and post-PCT blood panels measuring total testosterone, LH, FSH, SHBG, haematocrit, and a full lipid profile are strongly advised. Liver enzyme monitoring (ALT, AST) is recommended for any cycle exceeding four weeks, even though RAD-140 does not carry the 17-alpha-alkylation hepatotoxicity associated with oral anabolic steroids.

PCT: Post-cycle therapy is required following any RAD-140 protocol at or above 15mg per day, or any cycle lasting six or more weeks at 10mg. Standard protocols use Nolvadex (tamoxifen citrate) at 20mg per day for four weeks, or Clomid (clomiphene citrate) at 25–50mg per day for the same period. Natural testosterone recovery without PCT is possible after very short, low-dose use, but is not a recommended approach given RAD-140's suppressive potency.

Frequently asked questions

Why is RAD-140 considered the strongest SARM for muscle mass?
RAD-140 holds the highest published anabolic-to-androgenic ratio of any characterised SARM — approximately 90:1 in preclinical models, compared to MK-2866's ratio of around 3:1. This means RAD-140 activates androgen receptors in skeletal muscle far more aggressively per milligram, producing measurable lean mass accumulation at doses as low as 10mg per day. Its potency is the primary reason experienced users treat cycle length and PCT as non-negotiable, not optional.
What side effects does Testolone (RAD-140) cause at a 10mg dose?
At 10mg per day, RAD-140 commonly causes mild-to-moderate testosterone suppression over a 6–8 week cycle, which typically resolves with a standard SERM-based PCT. Some users report elevated aggression, sleep disruption, or mild lipid shifts. Androgenic effects such as hair acceleration are possible in genetically predisposed individuals. Hepatotoxicity risk is lower than with 17-alpha-alkylated oral steroids, but liver enzyme monitoring is still advisable for cycles exceeding four weeks.
Do you need a PCT after a RAD-140 cycle, and what should it include?
Yes — RAD-140 is sufficiently suppressive that PCT is required for the majority of users, particularly at doses of 15mg or above or cycles longer than six weeks. A standard protocol uses Nolvadex (tamoxifen) at 20mg per day for four weeks, or Clomid (clomiphene) at 25–50mg per day for the same duration. Blood work measuring LH, FSH, and total testosterone before and after the cycle is the most reliable way to confirm recovery.
What makes the 10mg tablet format ideal for a first RAD-140 cycle?
The 10mg per tablet concentration matches the recommended starting dose exactly, eliminating the measurement errors associated with liquid SARMs and the inaccuracy of tablet splitting. For a first RAD-140 cycle, beginning at one tablet per day for two weeks before assessing progress is the most controlled approach. Elbrus Pharmaceuticals' HPLC-verified tablets ensure each dose is accurate — critical when working with a compound this potent at relatively small absolute quantities.
How does RAD-140 from Elbrus Pharmaceuticals compare to liquid RAD-140 products in terms of dosing accuracy?
Pressed tablets with a declared HPLC-verified concentration offer superior dosing consistency compared to liquid suspensions, where settling, temperature variation, and pipette errors can introduce meaningful variance. Elbrus Pharmaceuticals' 10mg RAD-140 tablets are batch-tested at the finished-product stage using HPLC, confirming actual API content rather than relying on raw material certificates. For a compound where the therapeutic window between an effective dose and an overly suppressive one is narrow, tablet format is a practical safety advantage. (2) angle_used

Manufacturer

The production philosophy behind Elbrus Pharmaceuticals' RAD-140 tablet line is most clearly understood not from its testing procedures in isolation, but from the sequence in which those procedures are applied — and why that sequence is treated as non-negotiable. Elbrus positions its analytical framework around a single structural argument: for a compound with an anabolic potency as concentrated as RAD-140, the margin between a correctly dosed tablet and a materially over- or under-dosed one is narrow enough to carry real consequences for the user. That argument led the brand to establish two independent release gates — finished-product HPLC potency verification confirming declared 10mg API content, and LAL (Limulus Amebocyte Lysate) endotoxin screening for microbiological safety — neither of which can be bypassed or substituted by raw material supplier documentation. The Elbrus RAD-140 line is produced under ISO-aligned GMP conditions, with environmental monitoring records maintained throughout the compression and blister-sealing stages. Batch-level documentation is assigned at the point of release clearance, not retrospectively — meaning the lot number attached to a blister pack corresponds to a specific analytical record, not a generalised compliance statement. This approach reflects the founding rationale Elbrus articulated when entering the research-compound market: that the market's credibility problem was traceable to the gap between what manufacturers claimed and what they could document, and that closing that gap required treating analytical evidence as the release criterion rather than a supplementary assurance.

    RAD-140 hits different

    Most potent SARM I've run. 10mg ED for 8 weeks, strength was up within 10 days. Added 6kg bodyweight, lost a little fat at the same time so recomp effect is real. Did feel a bit tired in weeks 6 and 7 which told me suppression was kicking in, bloods confirmed test at 280 ng/dL mid-cycle. Ran a proper Nolva PCT and everything bounced back. Product is clearly dosed correctly.

    Strength through the roof

    8 weeks at 10mg. Squat went from 160kg to 185kg. aggression in training was noticeably up, focus sharpende. Sleep was vivid but I actually liked it. Lipids shifted a bit - HDL dropped from 58 to 41 so worth monitoring but nothing alarming. Product arrived fast and well packed. Elbrus tabs are consistent every time...
