Upcoming Classes
Introduction to Neuroinhibitor Injections
October 24, 2026 (Saturday) 9 - 5pm
- Follow up November 7, 2026 9-11am
January 9, 2027 (Saturday) 9-5pm
- Follow up January 23, 2027 9-11am
For Medical Professionals
This 1.25 day hands-on training of neuroinhibitor injections consists of in-person didactic lessons, hands-on supervised injection training, and a 2 week follow up to review results. Course is limited to 4 students to ensure proper supervision, lots of hands on opportunity, and time for questions.
​
-
Day 1: Didactic morning session, hands-on injecting of 1-2 models per student. (8 hours)
-
Day 2: 2 weeks after the full day training, each student will have the opportunity to see their models back to review results, product placement and dosage with PA Rossetti. (30 minutes per student, 15 minutes per model)
​
The 2 week follow up is arguably the most important part of training. Very few Toxin training courses will review results once the toxin has reached it's full effect. Assessment and critique after the tox has set in, is critical to injector success and growth.
​
Price: Introduction to Neuroinhibitors $1899
Model finding fee: $250 (each student is allowed up to 2 models)
