AGF-1 Review: Ingredients, Results & Better Alternatives

If you’re considering Pas Nutrition’s AGF-1 (Anabolic Growth Factor) testosterone booster, you’re likely wondering whether this premium-priced supplement delivers results worthy of its £69.99 price tag. After thorough testing and ingredient analysis, we’ve discovered this UK-based formula falls short of expectations despite containing some proven ingredients.

In this comprehensive AGF-1 review, we’ll examine the science behind each ingredient, analyze real-world effectiveness, and reveal why we scored it just 6.5/10 – plus show you three superior alternatives that cost significantly less.

Quick Verdict: AGF-1 Rating

Overall Score: 6.5/10

While AGF-1 contains legitimate testosterone-supporting ingredients like D-Aspartic Acid and Zinc Citrate, the formula lacks optimization and sophistication for its premium price point. You’re essentially paying football club sponsor prices for amateur league performance.

What is AGF-1 Testosterone Booster?

AGF-1, short for Anabolic Growth Factor, is a testosterone optimization supplement manufactured by Pas Nutrition, a UK-based company known for supplying professional football teams. The product claims to:

• Increase natural testosterone production
• Reduce cortisol (stress hormone) secretion
• Enhance androgen receptor availability
• Support post-workout recovery

The supplement requires taking 4 capsules twice daily (8 capsules total), which raises questions about both convenience and potential side effects from concentrated dosing.

AGF-1 Ingredients Analysis: The Science Behind Each Component

D-Aspartic Acid (3,000mg) – The Foundation

D-Aspartic Acid (DAA) serves as the primary testosterone-boosting ingredient in AGF-1. This amino acid regulator plays a crucial role in luteinizing hormone production within the testes, essentially acting as a testosterone precursor.

The Research: Studies show DAA can increase testosterone by 15-42% in men with below-average levels, though effects diminish in those with normal testosterone. The European Food Safety Authority recognizes doses up to 3,000mg as safe.

The Problem: AGF-1 delivers 3,000mg in just two daily servings rather than spreading it throughout the day. This concentrated dosing may cause:

• Digestive discomfort
• Headaches
• Mood fluctuations
• Reduced effectiveness due to poor absorption

Optimal Approach: Most successful protocols use 2,000-2,500mg divided into 3-4 smaller doses.

L-Carnitine Tartrate (2,000mg) – The Recovery Agent

L-Carnitine Tartrate primarily functions as a recovery supplement, potentially reducing exercise-induced muscle damage and improving hormonal responses to training.

The Theory: By minimizing muscle damage, more androgen receptors remain available to bind with testosterone, theoretically improving anabolic signaling.

The Reality: While L-Carnitine effectively aids recovery, peer-reviewed research showing direct testosterone enhancement remains limited. A 2018 study in the International Journal of Sport Nutrition found no significant testosterone changes despite improved recovery markers.

Verdict: Beneficial for athletes but questionable as a primary testosterone ingredient.

Phosphatidylserine (600mg) – The Cortisol Controller

This phospholipid, abundant in brain tissue, offers both cognitive and hormonal benefits when supplemented appropriately.

Cortisol Reduction: Research published in the Journal of the International Society of Sports Nutrition demonstrates phosphatidylserine can reduce post-exercise cortisol by up to 30%, indirectly supporting testosterone levels.

Dosing Excellence: The 600mg dose aligns perfectly with clinical studies, representing one of AGF-1’s strengths.

Individual Variability: Response varies significantly based on training intensity, stress levels, and individual biochemistry.

Zinc Citrate (10mg) – The Mineral Foundation

Zinc directly influences testosterone production through multiple pathways, making it essential for any legitimate testosterone supplement.

Mechanisms of Action:

• Stimulates luteinizing hormone production
• Acts as an aromatase inhibitor (reduces testosterone-to-estrogen conversion)
• Supports growth hormone secretion

Dosing Analysis: The 10mg dose meets the UK Recommended Daily Allowance, though athletes may benefit from 15-20mg due to increased losses through sweat.

Missing Synergy: AGF-1 lacks Vitamin B6, which significantly enhances zinc absorption – a puzzling omission at this price point.

What’s Missing from AGF-1’s Formula?

For £69.99, we expect a comprehensive testosterone optimization stack. AGF-1 notably lacks:

Critical Omissions

• Vitamin D3: Essential for testosterone synthesis (3,000-5,000 IU optimal)
• Magnesium: Works synergistically with zinc and DAA
• Vitamin B6: Enhances mineral absorption and reduces prolactin
• Fenugreek Extract: Proven to increase free testosterone
• Ashwagandha: Reduces cortisol while boosting testosterone
• Boron: Increases free testosterone by reducing SHBG

These missing ingredients appear in most premium testosterone boosters priced £20-30 less than AGF-1.

AGF-1 Dosing Protocol & Timing

Manufacturer Instructions:

• Morning: 4 capsules with breakfast
• Evening: 4 capsules with dinner
• Total: 8 capsules daily

Optimization Tips:

1. Take morning dose 30 minutes before breakfast for better absorption
2. Evening dose 2-3 hours before bed to avoid sleep disruption
3. Cycle 8 weeks on, 4 weeks off to maintain receptor sensitivity
4. Stack with Vitamin D3 and Magnesium for enhanced results

Expected Results Timeline

Based on ingredient profiles and user reports:

• Week 1-2: Improved recovery, slight energy increase
• Week 3-4: Modest strength gains, enhanced mood
• Week 5-8: Peak effects – 10-15% testosterone increase (if deficient)
• Week 8+: Diminishing returns, consider cycling off

Reality Check: Users with normal testosterone levels report minimal noticeable changes, questioning the value proposition.

Side Effects & Safety Considerations

While generally safe, potential side effects include:

Common (10-20% of users)

• Stomach upset from concentrated DAA dosing
• Mild headaches
• Initial sleep disruption

Uncommon (Less than 5%)

• Mood swings
• Acne flare-ups (in predisposed individuals)
• Temporary reduction in libido (paradoxical DAA response)

Safety Profile

AGF-1 uses well-researched ingredients within established safety parameters. However, the concentrated dosing schedule increases side effect risk compared to better-formulated alternatives.
