Compounds form the basis of a cycle; protectors are products used alongside it to address unwanted effects, without guaranteed protection; and PCT (post-cycle therapy) keeps that period’s plan separate. These categories organize records; they do not tell you what you need to use.
Tap Health in the bottom bar. Under Components, choose Compounds, Protectors, PCT, Syringes or Needles. Use the list’s add button.
Items saved here become available in the cycle builder. Choose the category where you intend to use the product.
