GLP-1 Weight Loss in South San Diego

The Hydro Drip Bar at 3030 Plaza Bonita Rd, Suite #118 brings medically supervised Tirzepatide and Retatrutide to National City, Chula Vista, Bonita, Otay Ranch, Eastlake, and the entire South San Diego corridor.

Unlike clinics that ship medication by mail, every injection at our National City location is administered in person by a licensed RN. Your dosage is monitored and adjusted weekly under Dr. Guillermo Castillo's medical oversight — giving you the accountability that actually drives results.

Pair your weekly GLP-1 shot with one of our IV drips — Myers Cocktail, Energy Boost, or Gluta Max — to replenish nutrients and reduce common side effects like fatigue and nausea.
