About Green Cap Health

The GLP-1 weight-loss injection opens at $79 for month one. Green Cap Health works only in Texas and owns both ends of the transaction: it is the clinical practice writing the prescription and the compounding pharmacy filling it, so no outside partner touches the order. Hair, skincare and sexual-wellness products share the shelf with compounded semaglutide.
