Frequently asked questions
Questions about The Trinity Stack
What is included in the Trinity Stack?
The Trinity Stack includes Micronized Creatine Monohydrate (5g per serving, tested at 100.8% assay), Complete Multivitamin (full-spectrum, HPLC and ICP-MS tested), and Vitamin D3 (2,000 IU label, heavy metals verified in-spec).
How much does the Trinity Stack save?
The Trinity Stack is $85. The three products total $94 bought separately, so the stack saves $9 and ships free in the U.S.
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?
Each covers a different job, with its own evidence. Creatine: across 69 trials, creatine with resistance training improved strength more than placebo (Kazeminasab et al., 2025). Vitamin D3: in national survey data, adults who took a multivitamin most days still tended to fall short on vitamin D (Blumberg et al., 2017), which is why D3 is a separate bottle. Multivitamin: covers the rest of the daily basics. No study has tested these three together as a stack, so we don’t claim they work better combined.
