Possible disadvantages

• Subscription Cost
  Exist requires a paid subscription after the initial trial period, which may be a barrier for some users.
• Privacy Concerns
  Collecting and integrating a wide range of personal data can raise privacy concerns, especially if the service is ever compromised.
• Data Overload
  The sheer amount of data available can be overwhelming for some users, making it challenging to identify the most relevant insights.
• Learning Curve
  New users may face a learning curve as they try to navigate the platform and make the best use of its features.
• Limited Free Features
  The free version offers limited functionality, which may not be sufficient for users looking to fully explore the platform before committing to a subscription.

• Half-life levels
  Models what is actually in your system from each compound's half-life, rather than showing a dose checklist.
• Reconstitution calculator
  Vial mg and bacteriostatic water in; concentration, draw volume and the exact mark on a U-100 syringe out.
• Vial inventory
  Counts each vial down as you log, with runway in days and low-stock warnings before you run out.
