Are all three products third-party tested?
Yes. Creatine Lot B25I013 tested at 100.8% assay. Multivitamin Lot MMV250805 passed HPLC, ICP-MS, and microbiological testing. Vitamin D3 Lot VS240798 tested for heavy metals by ICP-MS/MS with all analytes in-spec. All results are publicly available.
How do I take all three products?
Take 5g of creatine with water at any time of day. Take the multivitamin and Vitamin D3 together with a meal containing fat. Daily consistency matters more than specific timing.
Why these three supplements specifically?
Creatine monohydrate has over 500 peer-reviewed studies and is the most evidence-supported performance supplement available. Vitamin D3 deficiency affects 35–70% of athletic populations. A multivitamin closes the micronutrient gaps that training creates. Read more in our guide to foundational supplements for athletes.
