Pre-workout fans love a good origin story. BPI Sports first made its name in 2010 with a formula called 1.M.R.

BPI went bankrupt in 2023 and relaunched under Hi-Tech Pharmaceuticals. The brand then revived the name with 1.M.R OG.
BPI describes it as a recreation of the original formula, which it calls the founding father of pre-workouts.
We studied the label, the dosing and what people say online. The question is whether the comeback deserves the name.
Formula Breakdown
A 13.7g scoop makes one serving, and a tub holds 25 of them. The tub costs $34.99, which works out to $1.39 per serving.
Each scoop delivers two proprietary blends. The first is the Pump Matrix, which totals 9,625mg.
It contains beta-alanine and two kinds of citrulline (L-citrulline silicate and plain L-citrulline). It also has L-arginine and L-arginine AKG, along with betaine anhydrous and L-tyrosine.
By the standards of the category, that is a very large combined pump dose.
The second is the OG Energy Matrix, which totals 575mg. Caffeine anhydrous and theobromine sit alongside 2-Aminoisoheptane HCl. The blend also draws on extracts of geranium, guarana, yerba mate, schizandra and grape seed.
Because it is a proprietary blend, the label does not break out the exact milligrams of caffeine. Anyone who reacts strongly to stimulants, or who counts their intake closely, should note that.
Why DMHA Matters Here
The ingredient 2-Aminoisoheptane HCl is DMHA, a stimulant. In 2019, the FDA classified it as an unsafe food additive.
It also appears on the banned lists of both WADA and the NCAA.
BPI aims 1.M.R OG at “serious lifters” who want the intensity of the original formula. Some of that intensity comes from an ingredient that the FDA has flagged before.
Tested athletes should treat this product as off the table. Everyone else faces a personal risk-tolerance call, and we would rather say so clearly than tuck it into a footnote.
Early Feedback From Buyers
So far, BPI’s own product page carries no star rating or review count for this product. That fits a relaunched product better than a long-established listing.
In supplement forums, the early feedback is mixed. Some lifters rate its intensity as comparable to Cellucor’s C4.
Other lifters have used brands with more stimulant, such as Bucked Up and Alpha Lion, and they found it more ordinary. One recurring comment is that formulas without DMHA tend to feel smoother overall.
None of this makes it a bad product. Think of it as a solid, mid-tier stimulant pre-workout whose pump dose is unusually large, rather than a category-leading energy formula.
Flavors and Directions
Three flavors are offered at the moment: Fruit Punch, Blue Raspberry and Sour Gummy.
The directions call for mixing 1 scoop into 8oz of water and drinking it 15 to 30 minutes before training.
Since the caffeine content is undisclosed, we would begin with half a scoop the first time. That lets you gauge your tolerance before taking a full dose.
Where It Sits Among Rivals
Within the BPI range, the 1.M.R Vortex is the gentler option, and 1.M.R OG is the one with more stimulant.
Next to Cellucor’s C4, independent comparisons usually side with C4. It scores better on transparency, meaning disclosed dosages, and on the pump quality people report.
Our Verdict
1.M.R OG is a sensible mid-tier pre-workout for anyone who wants nostalgia plus a very large pump matrix. It works only if you are not competing in a drug-tested federation.
Look elsewhere if you are sensitive to stimulants, if you are drug-tested, or if you want every milligram disclosed on the label. That could mean another product in BPI’s own catalog, or a competitor that discloses its full stack.
