What it is
1st Phorm Level-1 Sustained Release Protein is a category-leading product in the protein space. Editorially-selected for protein-powder, sustained-release use cases. The label declares third-party testing where applicable.
Suggested use
Follow label dosing. As with any supplement, talk to a clinician before starting if you take prescription medications or have a chronic condition.
A note on selection
We list products that have a real track record (years of use, real users, published research where available) and avoid the wellness-aisle proprietary blends that hide doses behind 'patented formula' language.
