This comparison does not assign a generated winner or score.
- Abdominal subcutaneous (lateral to umbilicus)
- Adipose tissue
- Gradual depot release, 70–85% bioavailability
- 3–5 hours
- Systemic protocols, general tissue repair, no specific injury site
- Rotate quadrants every injection (4-site cycle)
- Anterior thigh (vastus lateralis) subcutaneous
- Moderate absorption, similar to abdominal
- 3–4 hours
- Alternative to abdominal for limb-based administration
- Alternate thighs every injection
- Anterior thigh (vastus lateralis) intramuscular
- Skeletal muscle
- Rapid absorption, 85–95% bioavailability
- 60–90 minutes
- Lower body injuries (knee, hamstring, quadriceps)
- Rotate within muscle group or alternate legs
- Deltoid intramuscular
- Upper body injuries (shoulder, rotator cuff, elbow)
- Rotate deltoid heads (anterior/lateral/posterior)
- Gluteal intramuscular
- Rapid absorption, large muscle mass
- Systemic IM protocols, large volume injections
- Alternate sides every injection
- Professional Assessment
- N/A
- Subcutaneous for systemic, IM near injury for localized repair
- Match administration route to protocol goal. Proximity matters for targeted tissue repair
- Structured rotation prevents lipohypertrophy and maintains absorption consistency
