MK-677 SubQ vs IM: Route Comparison
Bioavailability 96–98% (peaks at 60 min) 100% (peaks at 45 min) Functionally equivalent. 2–4% difference falls within biological variance Injection Depth 0.25–0.5 inches into adipose tissue 1–1.5 inches into muscle tissue SubQ requires less anatomical precisio

- Bioavailability
- 96–98% (peaks at 60 min)
- 100% (peaks at 45 min)
- Functionally equivalent. 2–4% difference falls within biological variance
- Injection Depth
- 0.25–0.5 inches into adipose tissue
- 1–1.5 inches into muscle tissue
- SubQ requires less anatomical precision
- Tissue Trauma
- Minimal. Adipose has low capillary density
- Moderate. Muscle highly vascularised
- SubQ produces 60–70% fewer injection site reactions
- Needle Length
- 5/16-inch to 1/2-inch, 27–30 gauge
- 1-inch to 1.5-inch, 23–25 gauge
- SubQ allows smaller gauge (less pain, slower absorption)
- User Error Rate
- 8–12% (mostly depth misjudgment)
- 34% (often fails to reach muscle)
- SubQ has significantly lower execution failure rate
- Volume Capacity
- 1–2mL maximum per site
- 3–5mL depending on muscle group
- MK-677 doses (0.5–1.0mL) fit comfortably in SubQ range
