The Science Behind Stealth: How Our Products Work

Evidence-Backed Design for Enhancement, Confidence, and Performance

At Stealth, our products are engineered using evidence-based physiological principles—from traction and tissue expansion to circulation and recovery support. While we do not make medical claims or offer medical devices, our design philosophy is inspired by real-world therapeutic practices and respected scientific research.

1. Penile Traction Therapy (PTT)

Penile Traction Therapy uses gentle, sustained stretching to encourage tissue elongation over time. Originally developed for medical conditions like Peyronie’s disease, PTT has since gained wider recognition for its ability to support penile length enhancement and curvature correction—non-surgically, and with minimal risk.

Scientific Research:

  • Martínez-Salamanca et al. (2014) reported significant length gains (+1.5 cm) and curvature reduction in men using PTT for 6+ hours daily during early-phase Peyronie’s. (ScienceDirect)
  • Gontero et al. (2009) found average length increases of up to 1.3 cm and improved curvature after 6 months of traction. (PubMed)

Stealth Products Based on This Principle: Innerwear, Strapless Innerwear and Sabre Skin

 2. Tissue Expansion & Stretch-Induced Growth

Tissue expansion is a well-established medical technique used in plastic and reconstructive surgery. It leverages the body’s natural ability to generate new skin, fascia, and connective tissue in response to consistent mechanical stretching. Over time, this process leads to permanent tissue growth and elongation—a principle that informs the core function of several Stealth products.

Scientific Research:

  • Ding et al. (2019) showed in Journal of Translational Medicine that tissue expansion activates macrophage-mediated skin regeneration, fostering collagen production and new blood vessel formation (BMC)

3. Magnetic Therapy, FIR Heat, & Circulation Enhancement

Far Infrared Radiation (FIR):

  • A systematic review covering cardiovascular and musculoskeletal applications found FIR enhances microcirculation, stimulates endothelial repair cells, and improves mitochondrial function in injured muscle—likely through vasodilatory mechanisms. (ScienceDirect)
  • In skeletal muscle cell studies, FIR increased mitochondrial biogenesis and oxygen consumption by ~1.5–3.4× and upregulated GLUT3 glucose transporters. (PubMed)

Static Magnetic Fields (SMFs):

  • Clinical and animal studies (0.1–0.6 T range) demonstrate SMFs can accelerate soft tissue wound healing, enhance microvascular blood flow, and reduce oxidative stress via nitric oxide signaling and improved antioxidant enzyme activity. (PubMed)
  • Additional research shows SMFs promoting bone and connective tissue repair, suggesting broader tissue regulatory effects beyond skin-level impacts. (ScienceDirect)
