RAD140(Vosilasarm)Raw Material Powder For Bodybuilding CAS:1182367-47-0
RAD140, known commercially as Testolone and colloquially by its developmental code name Vosilasarm, represents a significant advancement in the field of Selective Androgen Receptor Modulators (SARMs). Its emergence as a raw material powder has piqued the interest of the research community and bodybuilding enthusiasts alike, offering a unique profile distinct from traditional anabolic-androgenic steroids (AAS). This comprehensive analysis delves into the essence of RAD140 raw powder, its characteristics, potential applications, purported benefits, and critical pharmacological considerations, all framed within the context of its status as a non-approved research chemical.
What is RAD140 (Vosilasarm) Raw Material Powder?
RAD140 is a novel, non-steroidal, orally bioavailable SARM originally developed by Radius Health, Inc. for the potential treatment of conditions like muscle wasting associated with cancer (cachexia) and breast cancer. The "raw material powder" refers to the substance in its pure, unadulterated, and unformulated chemical state. It appears as a fine, white to off-white crystalline powder before being processed into solutions, capsules, or tablets.
Unlike anabolic steroids, which bind to androgen receptors throughout the body non-selectively, SARMs like RAD140 are engineered for tissue selectivity. Their molecular structure allows them to bind with high affinity and specificity to androgen receptors in bone and muscle tissue, while demonstrating a lower affinity for receptors in prostate tissue and sebaceous glands. This targeted mechanism is the foundational principle behind its proposed benefits and reduced side-effect profile compared to traditional AAS.


Distinctive Features of the Raw Powder
The raw powder form of RAD140 possesses several key features that are crucial for researchers and compounders:
1.High Purity: Pharmaceutical-grade raw powder is characterized by a high degree of purity, often exceeding 98% or 99%. This is critical for accurate dosing and ensuring that observed effects in a research setting are due to the compound itself and not contaminants.
2.Potency: RAD140 is renowned for its high anabolic potency. In preclinical models, it has demonstrated an ability to build lean muscle mass at doses significantly lower than those required for equivalent effects with steroids.
3.Stability: In its stable, anhydrous powder form, when stored correctly in a cool, dark, and dry environment, it has a prolonged shelf-life compared to a pre-made liquid solution, which may degrade over time.
4.Research-Grade Specificity: The raw powder is intended solely for in vitro (lab-based) research or, in a licensed setting, for pharmaceutical development. Its sale and marketing for human consumption are strictly prohibited by regulatory bodies like the FDA.
Applications and Purported Benefits
It is imperative to state that RAD140 is not approved for human consumption or for the treatment of any medical condition. Its applications are confined to controlled laboratory research. However, its mechanism of action suggests potential areas of interest for scientific study, which in turn inform the theoretical benefits discussed in bodybuilding circles.
Theoretical Research Applications:
●Investigation of Muscle Protein Synthesis: Studying its anabolic pathways and comparing its efficacy to other anabolic agents in cell cultures and animal models.
●Research into Androgen Receptor Signaling: Understanding the nuances of tissue-selective activation of androgen receptors.
●Exploring Neuroprotective Properties: Early-stage research suggested potential benefits for cognitive function and neuroprotection, a unique angle among SARMs.
Purported Benefits (Based on Preclinical Data and Anecdotal Reports):
●Significant Lean Mass Accretion: RAD140 is considered one of the most potent SARMs for building muscle mass. It is theorized to promote nitrogen retention and increase protein synthesis, leading to substantial gains in lean body mass.
●Enhanced Strength and Endurance: Users often report rapid increases in strength, allowing for more intense and productive training sessions, which further contributes to muscle growth.
●Fat Loss: Its androgenic activity may help increase metabolic rate and promote lipolysis (fat breakdown), leading to improvements in body composition and muscle definition.
●Improved Bone Density: Like other agents acting on androgen receptors, it may contribute to increased bone mineral density, though this is less of a focus in the bodybuilding context.
●Low Androgenic Side Effects (Theoretically): Due to its selective action, it is hypothesized to avoid or minimize traditional steroid side effects such as severe acne, accelerated male pattern baldness, and prostate enlargement. However, this selectivity is not absolute in humans.
Dosage, Cycle, and Half-Life: A Research Perspective
Any discussion of dosage and cycling is extrapolated from anecdotal user reports and is not based on clinical human trials. Self-administration carries significant health risks.
●Dosage: The common dosage range discussed in online forums for male research subjects is typically between 10 mg to 20 mg per day. Some advanced users may experiment with higher doses, but this exponentially increases the risk of side effects and suppression of natural testosterone production. A conservative approach is strongly advised.
●Cycle Length: A typical "on-cycle" period reported is 8 to 12 weeks. Cycles longer than this significantly heighten the risk of substantial hormonal suppression and potential liver strain.
●Half-Life: RAD140 has a relatively long half-life, estimated to be between 20 to 24 hours. This long half-life means the compound remains active in the body for an extended period, allowing for once-daily dosing to maintain stable blood plasma levels. This also means that side effects, if they occur, may persist for some time after the last dose.
Post-Cycle Therapy (PCT) Considerations
Despite its tissue selectivity, RAD140 is still a suppressive compound. It signals the body to stop producing its own natural testosterone via the hypothalamic-pituitary-testicular axis (HPTA). The degree of suppression varies by individual, dosage, and cycle length but is a near-certainty.
Therefore, a Post-Cycle Therapy (PCT) protocol is considered essential by the community to help restart natural testosterone production. A PCT protocol typically begins after the compound has cleared the system sufficiently (a few days after the last dose, given its half-life). It involves the short-term use of compounds like:
●SERMs (Selective Estrogen Receptor Modulators): Such as Tamoxifen (Nolvadex) or Clomiphene (Clomid). These drugs block estrogen receptors in the pituitary, prompting the body to increase production of Gonadotropin-Releasing Hormone (GnRH), Follicle-Stimulating Hormone (FSH), and Luteinizing Hormone (LH), which in turn stimulate the testes to produce testosterone again.
A common PCT protocol might involve 4-6 weeks of a SERM. However, the necessity and specifics of PCT should ideally be determined by blood work before, during, and after a cycle to assess hormonal levels (total testosterone, free testosterone, LH, FSH).
