Black Market CUTS DiamondBlack Market's strongest thermogenic pre-workout: 5g of pure L-citrulline, 3.2g beta-alanine, 300mg of caffeine from three sources, and 2.5g of carnitine across three forms. Every dose disclosed.Full disclosure is the real upgrade over standard CutsThe original AdreNOlyn Cuts puts most of its formula inside a proprietary "Fat Burning Matrix" — you get a blend total, not individual doses.Cuts Diamond discloses everything.

On a thermogenic product, where underdosing is common, that matters more than the ingredient list.ProGBB is the genuinely clever ingredient — here is whyThis is the most interesting thing in the formula and it deserves proper explanation.The problem with carnitine supplements: carnitine's job is transporting fatty acids into mitochondria to be burned. But muscle carnitine uptake is insulin-dependent — carnitine taken without a meaningful carbohydrate load is largely not taken up by muscle at all. Taken as a pre-workout, often fasted, the conditions are close to the opposite of what uptake requires. We explain this in full on our L-Carnitine page.GBB sidesteps that problem entirely. Gamma-butyrobetaine is the direct biosynthetic precursor to carnitine — your body converts GBB into carnitine internally, using its own enzymes. So rather than trying to transport carnitine into muscle from outside, GBB raises the carnitine your body produces itself.That is why it is sometimes called "super carnitine," and mechanistically it is a genuinely smarter approach than swallowing more carnitine.⚠ But sweating is not fat burningThis is the honest part, and it matters.GBB's most reliable, noticeable effect is intense sweating. You will feel it, and it is why the ingredient appears in thermogenics — it produces a sensation people associate with fat loss.Sweating is heat dissipation, not fat oxidation. They are different processes. You can sweat heavily and burn no additional fat; you can burn fat while perfectly cool. The feeling of a product "working" is not evidence that it is doing what you bought it for.And the deeper point stands regardless of the delivery mechanism: most people are not carnitine-deficient, so raising carnitine — however cleverly — does not necessarily increase the rate at which fat is oxidised. Supplementing something that is not the bottleneck does not remove the bottleneck.What actually drives fat loss is a sustained caloric deficit. The caffeine here genuinely helps — it is a real thermogenic and a real appetite suppressant.

Black Market CUTS Diamond

Black Market's strongest thermogenic pre-workout: 5g of pure L-citrulline, 3.2g beta-alanine, 300mg of caffeine from three sources, and 2.5g of carnitine across three forms. Every dose disclosed.

Full disclosure is the real upgrade over standard Cuts

The original AdreNOlyn Cuts puts most of its formula inside a proprietary "Fat Burning Matrix" — you get a blend total, not individual doses.

Cuts Diamond discloses everything. That means you can do exactly what we do on these pages: check whether the doses are meaningful, and decide for yourself. On a thermogenic product, where underdosing is common, that matters more than the ingredient list.

ProGBB is the genuinely clever ingredient — here is why

This is the most interesting thing in the formula and it deserves proper explanation.

The problem with carnitine supplements: carnitine's job is transporting fatty acids into mitochondria to be burned. But muscle carnitine uptake is insulin-dependent — carnitine taken without a meaningful carbohydrate load is largely not taken up by muscle at all. Taken as a pre-workout, often fasted, the conditions are close to the opposite of what uptake requires. We explain this in full on our L-Carnitine page.

GBB sidesteps that problem entirely. Gamma-butyrobetaine is the direct biosynthetic precursor to carnitine — your body converts GBB into carnitine internally, using its own enzymes. So rather than trying to transport carnitine into muscle from outside, GBB raises the carnitine your body produces itself.

That is why it is sometimes called "super carnitine," and mechanistically it is a genuinely smarter approach than swallowing more carnitine.

⚠ But sweating is not fat burning

This is the honest part, and it matters.

GBB's most reliable, noticeable effect is intense sweating. You will feel it, and it is why the ingredient appears in thermogenics — it produces a sensation people associate with fat loss.

Sweating is heat dissipation, not fat oxidation. They are different processes. You can sweat heavily and burn no additional fat; you can burn fat while perfectly cool. The feeling of a product "working" is not evidence that it is doing what you bought it for.

And the deeper point stands regardless of the delivery mechanism: most people are not carnitine-deficient, so raising carnitine — however cleverly — does not necessarily increase the rate at which fat is oxidised. Supplementing something that is not the bottleneck does not remove the bottleneck.

What actually drives fat loss is a sustained caloric deficit. The caffeine here genuinely helps — it is a real thermogenic and a real appetite suppressant. The rest ranges from mechanistically interesting to modestly supported.

We would rather tell you that than let you buy on the sweat.

Three caffeine forms — and this is the full set

300mg from caffeine anhydrous, caffeine citrate and di-caffeine malate, which is unusual because it uses all three approaches at once:

Caffeine citrate — absorbs fastest. Sharpens the onset
Caffeine anhydrous — the standard, peaking at 30 to 45 minutes
Di-caffeine malate — caffeine bonded to malic acid as a salt, releasing more gradually and generally gentler on the stomach

Layering fast, standard and slow flattens the curve across the session. It does not reduce the total — 300mg is still 300mg, three quarters of the 400mg daily figure the FDA cites.

⚠ Cautions worth reading

Synephrine (bitter orange, Advantra Z), 40mg. Structurally related to ephedrine and a genuine stimulant.

WADA-prohibited in competition — not for tested athletes
⚠ Do not take with grapefruit juice. Grapefruit inhibits CYP3A4, the enzyme that metabolises synephrine, which can raise blood levels unpredictably

Mucuna pruriens (L-DOPA) — a direct dopamine precursor. Black Market's own label warns against combining this product with MAO inhibitors, and that warning is there for a reason. If you take antidepressants or any psychiatric medication, speak to your doctor before using it.

Combined stimulant load: 300mg caffeine plus synephrine plus GBB is substantial. Not for anyone with a cardiovascular condition, high blood pressure or an anxiety disorder. Black Market advise discontinuing before surgery and stopping if you experience rapid heartbeat, dizziness, severe headache or shortness of breath.

One serving in 24 hours. No exceptions.

The rest of the thermogenic side, assessed

Frequently asked questions

What is ProGBB?
Gamma-butyrobetaine, the direct biosynthetic precursor to carnitine. Rather than supplying carnitine that must be transported into muscle, it raises the carnitine your body produces internally — sidestepping the insulin-dependent uptake problem.

Why does it make me sweat so much?
That is the GBB. It is the ingredient's most reliable effect — but sweating is heat dissipation, not fat oxidation. The two are different processes.

Does the carnitine burn fat?
Not reliably. Most people are not carnitine-deficient, so raising carnitine does not necessarily increase fat oxidation. A caloric deficit is what produces fat loss; the caffeine genuinely assists.

How is it different from regular Cuts?
Cuts Diamond has a fully disclosed label; standard AdreNOlyn Cuts hides most doses in a proprietary blend. Diamond also drops raspberry ketone and adds ProGBB and better citrulline dosing.

Why three forms of caffeine?
Citrate absorbs fastest, anhydrous is standard, di-caffeine malate releases gradually. Layering them flattens the curve — though the 300mg total is unchanged.

Can I take it if I am drug tested?
No. Synephrine is WADA-prohibited in competition.

Why can't I have grapefruit with it?
Grapefruit inhibits CYP3A4, the enzyme that metabolises synephrine, which can raise blood levels unpredictably.

Why does it taste slightly spicy?
CaloriBurn GP — grains of paradise extract. That is expected rather than a fault.
