For non-hormonal subcutaneous or intramuscular chemotherapy, use CPT 96401
In double-blind, placebo-controlled trials, daily application of GHK-Cu cream at 3% concentration for 12 weeks produced a 70% increase in skin collagen thickness as measured by ultrasound imaging, a 40% increase in skin elasticity, and visible reduction in fine lines and wrinkles
Pinch the fat when you inject, to prevent accidental muscle penetration, and you should be alright

What subcutaneous (SubQ) injection means Subcutaneous = under the skin, into fat layer: Not into muscle (that's intramuscular) Not into vein (that's intravenous) Into fatty tissue between skin and muscle Slower absorption than IM, but adequate for BPC-157 Why SubQ for BPC-157: Easy to self-administer Less painful than IM Works well for systemic healing Can inject near injury sites Injection sites for SubQ Best locations: Abdomen (2 inches away from belly button) Thighs (front and outer sides) Upper arms (back of arm, need help or flexibility) Love handles/flanks Near injury: Can inject within 2-3 inches of injury Example: Shoulder injury = inject into shoulder area fat Knee injury = inject into thigh near knee Local injection may speed healing to that area Rotate sites: Don't inject same spot repeatedly Prevents tissue damage and scar tissue Rotate between abdomen, thighs, arms Different spot each injection SubQ injection step-by-step Step 1: Gather supplies Reconstituted BPC-157 (refrigerated) Insulin syringe (29-31 gauge, 1/2 inch needle) Alcohol wipes Sharps container for disposal Step 2: Prepare dose Remove BPC-157 from fridge Wipe vial top with alcohol Draw calculated dose (e.g., 25 units = 250mcg if using 2mg/ml concentration) Remove air bubbles Recap needle Step 3: Prepare injection site Choose injection area Clean with alcohol wipe Let dry (30 seconds) Step 4: Inject Pinch skin to create fold (makes it easier) Insert needle at 45-90 degree angle into pinched skin Insert fully (it's a short needle) Slowly inject (take 3-5 seconds) Remove needle quickly Step 5: After injection Apply gentle pressure with alcohol wipe if bleeding (rare) Don't massage injection site Return BPC-157 vial to refrigerator immediately Dispose of needle in sharps container Pain level: Minimal

Reconstituted stability: 30 days at 2-8C when reconstituted with bacteriostatic water
