RAD 140, also known as Testolone, is an investigational selective androgen receptor modulator (SARM) under development as a therapeutic alternative to testosterone replacement therapy. Although never FDA-approved, it has become widely used in fitness communities for its muscle-building and strength-enhancing effects.
Chemically, RAD 140 is a nonsteroidal synthetic agent designed for targeted anabolic effects in muscle and bone. By stimulating androgen receptors, it increases muscle protein synthesis and growth, similar to anabolic steroids, but without significant side effects on prostate tissues or serum lipid profiles.
Due to its potent tissue-selective anabolic effects, RAD 140 has rapidly gained popularity among bodybuilders, athletes, and fitness enthusiasts looking to improve physique and performance. It remains in a legal gray area for enhancement use.
How Does RAD 140 Work?
RAD 140 acts as a selective androgen receptor modulator with high affinity and selectivity toward activating androgen receptors in muscle and bone tissues. It does not bind strongly to prostate receptors.
By binding to androgen receptors, RAD 140 stimulates the synthesis of contractile muscle proteins while also inhibiting protein breakdown. This leads to pronounced increases in muscular strength and lean body mass.
RAD 140 also increases nitrogen retention within muscles, a foundational process for tissue growth and repair. The combined effects enable RAD 140 to rapidly increase muscle cell growth, size, and strength without excessive fluid retention or androgenic side effects.
Benefits of RAD 140:
- Increases lean muscle mass
- Enhances strength
- Boosts endurance and stamina
- Reduces body fat
- Accelerates muscle recovery
- Does not cause liver strain
- Well-tolerated with low side effects
With its targeted anabolic properties, RAD 140 can significantly enhance physique and performance for bodybuilders, athletes, and fitness enthusiasts.
Side Effects of Rad 140:
Compared to traditional anabolic steroids, RAD 140 is considered relatively mild in terms of side effects.
- May suppress natural testosterone
- Headaches, lethargy
- GI distress, nausea
- Hair loss due to genetic predispositions
- Potential irritability/aggression
- Acne (but less than traditional steroids)
RAD 140 is not completely side-effect-free, especially with longer cycles or higher dosages. But research shows it has a much improved safety profile compared to most anabolic agents.
Effective doses for physique and performance enhancement range from 10 to 20 mg per day. However, it appears that 20 mg per day, split into 10 mg twice daily, provides the ideal balance of anabolic effects versus side effects for most users. Cycles typically range from 4 to 12 weeks in length, followed by proper PCT. As with any SARM, extended cycles or high dosages increase the risk of side effects. Starting low and assessing individual responses is advised.
Where to Buy RAD 140 online
As an investigational research compound, RAD 140 is sold online by some specialty SARM suppliers like BuyPeptidesusa for the purposes of scientific investigation. The use of these research chemicals by humans for bodybuilding or enhancement purposes remains a legal gray area.
When purchasing SARMs like RAD 140 from an online vendor, thoroughly vet the company and read unbiased customer reviews before placing orders. Only buy from trusted U.S.-based sources with a long track record of delivering pure, verified compounds.
Consult a physician if planning to use any unscheduled research chemicals obtained online to ensure proper oversight and management of your health and hormone levels. Although promising, these experimental agents come with unknown long-term effects that require prudent use.
