Analysis

Citrulline, beta-alanine, betaine, theanine, theobromine, and AstraGin form a recognizable pre-workout combination. The supplied caffeine amount is 180 grams, an extreme safety problem that outweighs all possible benefits.

Theobromine is clearly disclosed at 50 mg and serves as a supporting stimulant-like compound. Other performance ingredients have moderate listed amounts, but the formula cannot be responsibly recommended while caffeine data remains unverified.

Flavor and serving cost are not meaningful decision factors under these circumstances. Confirm the physical label or manufacturer information before considering any use.

Who is it for
  • No user until the caffeine amount is verified
  • Adults who can confirm corrected labeling and tolerate stimulants
  • Experienced pre-workout users only after verification
Best for
  • Label verification before any use
  • Combined stimulant support only if the caffeine data is corrected
  • Users seeking a 50 mg theobromine addition after verification

Pros

  • Clearly lists 50 mg of theobromine
  • Pairs theanine with stimulant ingredients
  • Includes several familiar pre-workout actives

Cons

  • Supplied data lists 180 grams of caffeine
  • Flavor-system excipients are not detailed
  • Theobromine is only a supporting amount

Warnings

  • Do not use while the listed 180-gram caffeine amount remains unverified; that amount represents an acute medical emergency risk.
  • Caffeine and theobromine can combine to cause rapid heartbeat, restlessness, nausea, or sleep disruption.
  • Beta-alanine commonly causes temporary tingling, and the formula should not be combined with other stimulants.

Nutrient quality

57 Moderate impact

The active selection fits exercise performance, but several doses are below common full-serving targets. The listed caffeine unit creates a severe safety and data-quality problem that overrides the otherwise coherent design.

Ingredient transparency

70 High impact

Each listed active has an amount and no proprietary blend hides dosing. The implausible caffeine unit, missing flavor system, and incomplete directions make the supplied label unsafe to interpret literally.

Customer satisfaction

58 Moderate impact

The aggregate rating is favorable, but the limited review count weakens confidence. No detailed feedback is supplied, so repeated complaints and purpose fit cannot be judged.

Value for money

44 Lower impact

Moderate performance ingredients cannot justify value until the implausible caffeine unit is resolved. The serving should not be treated as safe or competitive from the supplied label data.

Theobromine · 50 mg OverallScore89
A+ Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyB+ Value

Standalone theobromine is clearly disclosed, but the amount is better suited to sensitive users or a combined pre-workout stack than to strong theobromine-focused effects. The formula pairs it with caffeine and L-theanine, so stimulant exposure comes from more than theobromine alone. Serving cost is favorable, while the supplied details do not establish a purity percentage or identify the flavor-system excipients.

74 Performance

Nitrosurge Shred Black Cherry

Jacked Factory
<p>Caffeine, theanine, acetyl-L-carnitine, citrulline, beta-alanine, and theobromine form a clearly measured energy-and-focus blend. Citrulline and beta-alanine remain below stronger performance amounts, and serving cost is higher.</p>
68 Performance

Energy

LifeSeasons
<p>Theobromine and theanine anchor a gentler energy blend with green tea and several adaptogens. Many adaptogens are lightly dosed, and the formula costs more per serving.</p>
71 Performance

Kre-Alkalyn Hardcore

All American EFX Sports
<p>Buffered creatine plus disclosed caffeine and theobromine gives clearer stimulant information than the original’s implausible caffeine entry. The stimulant stack may still increase jitteriness, rapid heartbeat, or sleep disruption.</p>
80 Budget

Theobromine 400 mg

Nutricost
<p>A focused theobromine capsule costs much less and provides far more of that specific active. The amount is aggressive for sensitive users and does not replace citrulline, beta-alanine, betaine, caffeine, or theanine.</p>
71 Budget

Kre-Alkalyn Hardcore

All American EFX Sports
<p>Creatine, caffeine, and theobromine provide workout energy at a lower serving cost. The multi-stimulant combination may increase jitteriness, rapid heartbeat, or sleep disruption, and creatine is modest.</p>
64 Budget

Steel-Libido Pink For Women

Irwin Naturals
<p>Theobromine, ginseng, maca, and other botanicals cost less per serving and offer broader energy support. Most amounts are modest, while the stimulating mix and black pepper extract create interaction concerns.</p>
80 Value

Theobromine 400 mg

Nutricost
<p>A single clearly disclosed active provides much more theobromine at a substantially lower serving cost. The high amount may cause nausea, headache, restlessness, or a rapid heartbeat, and it lacks broader workout ingredients.</p>

Kre-Alkalyn Hardcore

All American EFX Sports
<p>Creatine, caffeine, and theobromine provide broader workout coverage at a lower serving cost. The creatine amount is modest and combined stimulants may be poorly tolerated.</p>

NitroSurge Pre-Workout Blue Raspberry

Jacked Factory
<p>The active profile closely matches the original at the same serving cost, so it is a flavor alternative rather than a genuine value upgrade. Its listed caffeine unit is also implausible and must be checked against the physical label before use.</p>
