Your first VIP vial comes as a nasal spray, not an injectable. Standard compounding: 5 mg vial reconstituted in 10 mL bacteriostatic water gives 500 mcg/mL. Each spray actuation delivers 0.1 mL, which equals 50 mcg per spray. Four sprays per dose means 200 mcg total. The biggest mistake people make is starting VIP too early. MARCoNS must be eradicated and confirmed negative on retest. VCS must be passing. If you skip those prerequisites, you'll spend $189 to $399 per month on a peptide that won't work because the underlying inflammation source is still active. Alternate nostrils with each spray (two sprays per nostril per dose). Morning dosing before food is standard. If you're sensitive, ask your prescriber about a 1:10 or 1:100 dilution for the first week; that dilution step makes initiation worsening much less likely. Get fasting lipase drawn before you start. No exceptions. Monthly lipase for three months after that.
