1MR is BPI Sports’ One More Rep
1MR, also styled 1.M.R., names BPI Sports’ pre-workout family. Treating it as a generic description of intense supplements hides an important detail: multiple formulas have used the name. This guide focuses on the manufacturer’s currently displayed OG formula and separates it from other versions.
What the OG label discloses
The BPI 1MR OG page and its Blue Raspberry Supplement Facts image show a 13.7 g scoop, 25 servings and two blends:
- Pump Matrix, 9,625 mg: beta-alanine, citrulline and arginine ingredients, betaine and tyrosine.
- OG Energy Matrix, 575 mg: caffeine anhydrous, 2-aminoisoheptane HCl, theobromine and botanical ingredients including guarana and yerba mate.
These totals are combined blend weights. The 575 mg figure is not a caffeine dose. A separate caffeine total is not disclosed in the inspected panel, and the blend also prevents verification of individual citrulline or beta-alanine doses. Do not borrow a caffeine figure from an older 1MR review.
The listed DMHA ingredient is a serious concern
The FDA identifies 2-aminoisoheptane as a name for DMHA. It considers DMHA an unsafe food additive and supplements containing it adulterated under US law. The presence of that ingredient in the displayed OG formula is therefore more consequential than choosing a preferred stimulant strength.
This guide does not recommend a DMHA-containing product. Taking a smaller scoop or describing yourself as stimulant-tolerant does not resolve the ingredient concern. A product appearing on a manufacturer’s website is not evidence of FDA approval.
Keep the versions separate
BPI’s 1MR Vortex listing describes a separate 50-serving, beta-alanine-free product. Its November 2022 1MR introduction describes a different generation built around glycerol, caffeine, mucuna, theobromine, theacrine and methylliberine. Neither source justifies merging those ingredients with the OG panel.
Check the complete product name, country, serving weight and actual ingredient panel before comparing a tub. A complete allergen and cross-contact statement was not verified for the pictured OG flavor; do not infer allergen safety from a partial ingredient list. This is a label-based review, without personal taste, workout or safety testing.
