Quality and testing
A formula is only as good as the facility that makes it and the lab that checks it. Here is how WeGoSlim is produced and what every batch goes through before it reaches you.
WeGoSlim is manufactured in the United States in a facility that is FDA-registered and operates under current Good Manufacturing Practices (cGMP). In plain terms, that means documented procedures, controlled raw materials, and records that follow each batch from intake to finished bottle. Pennfield Wellness, LLC oversees distribution for the 2026 production cycle through this authorized portal.
Each production run is sampled and screened by Calderwood Diagnostics, LLC, an independent ISO/IEC 17025 accredited laboratory, across the following:
High-performance liquid chromatography (HPLC) confirms each botanical is what the label says it is, not a cheaper substitute.
Active markers are measured against the label dose so each capsule delivers what the formula promises.
Screening by ICP-MS keeps lead, arsenic, cadmium, and mercury within strict limits (< 0.8 ppm for the current batch).
Total counts and pathogen screening confirm the batch is within USP limits (Pass (USP <61>/<62>)).
Botanical inputs are screened so residues stay within accepted thresholds.
Botanical inputs are selected for standardized active content where it matters, such as oleuropein in olive leaf and capsaicinoids in cayenne, so the dose on the label reflects the dose in the capsule. The formula is non-GMO and free of gluten, dairy, and soy. It contains no caffeine or added stimulants by design.
Quality is the process; verification is the proof. The result of this testing for the batch now shipping, including its purity figure and certificate of analysis, is published on the verification page so you can match it to the bottle in your hand. If you would like to understand the formulation reasoning, the science page covers it in depth.
