Analysis

The product supplies 5 grams arginine alpha-ketoglutarate and 2.5 grams ornithine HCl, which are the only ingredients present at clearly substantial athletic amounts. The six-tablet serving is the practical cost of delivering that dose.

Glutamine, carnitine, beta-sitosterol, and gamma oryzanol are small additions and unlikely to contribute much at the listed amounts. Vitamin B6 at 20 mg adds nutritional support but is high enough to matter when stacking.

The formula fits adults specifically seeking arginine and ornithine rather than general daily energy. Users with low blood pressure, digestive sensitivity, or recurrent cold sores should weigh the arginine-related trade-offs.

Who is it for
  • Adults seeking high-dose arginine and ornithine
  • Athletic users comfortable with six tablets
  • People not using it as a general energy supplement
Best for
  • Arginine and ornithine supplementation
  • Pre-workout amino-acid use
  • A stimulant-free athletic formula

Pros

  • Provides 5 grams arginine alpha-ketoglutarate
  • Includes 2.5 grams ornithine
  • No caffeine is listed
  • Core amino-acid amounts are disclosed

Cons

  • Requires six tablets
  • Glutamine and carnitine are token amounts
  • Weak fit for everyday energy
  • Vitamin B6 adds unnecessary long-term exposure

Warnings

  • Arginine may lower blood pressure and can add to antihypertensive or nitrate effects
  • Arginine may cause stomach upset and may trigger cold-sore recurrence in susceptible users
  • Vitamin B6 at 20 mg can add materially to long-term intake when combined with other supplements

Nutrient quality

72 High impact

Arginine alpha-ketoglutarate and ornithine hydrochloride are clearly identified amino-acid forms. Arginine and ornithine are substantial, while glutamine, carnitine, and phytosterols are modest.

.

Ingredient transparency

81 Highest impact

Active amounts and amino-acid forms are clearly stated. Complete non-active ingredient details are not included in the supplied label data.

.

Customer satisfaction

70 High impact

The supplied average rating provides limited high-level context. Detailed firsthand feedback is unavailable, so recurring complaints and purpose fit cannot be assessed.

.

Value for money

57 Moderate impact

Large arginine and ornithine doses support some value at the moderate serving cost. Weak evidence for the claimed role and small secondary doses limit effective value.

The formula centers on large arginine and ornithine amounts with several smaller performance-oriented compounds. Its growth-hormone and athletic positioning is poorly aligned with foundational daily health.

Evidence for meaningful general-health benefits from this combination is limited, and several minor ingredients are too small to add much depth. The large amino-acid serving may cause stomach upset and can lower blood pressure, especially when combined with blood-pressure medicines.

B+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

The disclosed L-arginine alpha-ketoglutarate form and substantial serving amount align well with the collection. The label clearly identifies the active amount, though it does not state the molecular ratio. The total active content also provides strong value across the container.

Vitamin B6 (Pyridoxine Hydrochloride) · 20 mg OverallScore59
D+ Active Ingredient Quality & BioavailabilityA Dose, Safety & Label TransparencyF Value

Pyridoxine hydrochloride is a precursor form, and no riboflavin cofactor is listed to support conversion. The 20 mg dose sits in the preferred range for metabolic and neurological support. Price per serving is poor for pyridoxine hydrochloride.

L-Arginine AKG Unflavored

BodyTech
<p>A clearly disclosed, substantial arginine alpha-ketoglutarate serving closely matches the original’s main exercise ingredient without the lightly dosed extras. Molecular-ratio details are missing, and arginine can compound nitrates or blood-pressure medicines, but the focused dose is more coherent.</p>
89 Performance

P-5-P (Pyridoxal-5-Phosphate) 40 mg Double Strength

Swanson
<p>Active pyridoxal phosphate provides a better vitamin B6 form than the original’s unspecified B6 entry. It does not supply arginine alpha-ketoglutarate or ornithine, so the improvement is limited to the vitamin component rather than exercise performance coverage.</p>
81 Performance

Pyridoxal 5'-Phosphate

Thorne
<p>Ready-to-use P-5-P provides a clearly identified vitamin B6 form at a moderate high-potency amount. The formula omits the original’s amino acids, but it is more transparent for users seeking only the B6 component and avoiding an unsupported growth-hormone blend.</p>
84 Budget

Arginine AKG 1 gram

Swanson
<p>It costs much less per serving while retaining arginine alpha-ketoglutarate in a simple focused capsule. The serving is smaller and ornithine, glutamine, carnitine, and vitamin B6 are absent, but the core exercise ingredient remains intact.</p>
89 Budget

P-5-P 50 mg

Country Life
<p>Active pyridoxal phosphate provides a more direct vitamin B6 form at a much lower serving cost. It omits arginine alpha-ketoglutarate and ornithine, so it is appropriate only when B6 support rather than the original’s exercise-amino-acid design is wanted.</p>
89 Budget

BioCoenzymated Pyridoxal 5'-Phosphate 50 mg

Natural Factors
<p>Active pyridoxal phosphate offers focused vitamin B6 coverage at a substantially lower serving cost. The narrower formula does not provide the original’s arginine alpha-ketoglutarate or ornithine, but its B6 form quality is stronger.</p>
84 Value

P-5-P 50 mg

Nutricost
<p>Active P-5-P provides ready-to-use vitamin B6 at very low serving cost. The amount is high and the formula lacks arginine alpha-ketoglutarate, yet it offers efficient value when the original’s B6 component is the only priority.</p>
87 Value

Vitamin B-6 50 mg

Nature's Way
<p>A mixed active and precursor B6 blend improves form detail and comes at a very low serving cost. Arginine alpha-ketoglutarate and ornithine are absent, so it offers nutritional B6 value rather than the original’s exercise-focused amino acids.</p>
79 Value

P-5-P 50 mg

NOW
<p>The product name indicates P-5-P and the formula adds magnesium bisglycinate at a low serving cost. The ingredient entry does not explicitly confirm the B6 form and no arginine alpha-ketoglutarate is present, but the mineral-supported B6 approach is more economical.</p>
