What Does the P-Shot Target in Terms of Size?
The P-Shot delivers PRP (Platelet-Rich Plasma) directly into penile tissue, stimulating angiogenesis (blood vessel formation), collagen production, and tissue regeneration. These biological changes can contribute to modest increases in length and, more reliably, girth over 8–12 weeks. The effect results from improved tissue health and blood flow capacity rather than artificial augmentation.
What Does the Clinical Evidence Show?
Clinical studies on PRP penile injections consistently report improvements in erectile quality and, in some cases, modest size gains. A 2019 study found that a subset of patients reported measurable girth increases averaging 0.5–1.0 cm at 12 weeks. Length improvements are less consistently reported and tend to be subtle rather than dramatic.
Who Sees the Most Noticeable Size Improvements?
Men who experience the greatest size improvements tend to have had ED-related reduction in erection quality prior to treatment. As PRP restores vascular and tissue health, the penis returns closer to its maximum natural state — which patients perceive as a size increase. Younger patients with mild-to-moderate ED, and those who use a vacuum erection device post-treatment, tend to see the most pronounced improvements.
Setting Realistic Expectations
The P-Shot should not be promoted as a guaranteed size enhancement procedure. For most patients, the primary benefits are improved erectile quality, sensitivity, and stamina. Any size improvements are a welcome secondary effect. If your primary goal is size increase, the P-Shot may disappoint; if your primary goal is erectile health, any size improvement is a bonus.
