Grip Strength as a Longevity Indicator

Happy Wednesday!

Today, I'd like to delve into a question I received from one of my readers.

Here’s what they wrote:

Most of you know my philosophy.

When it comes to optimization, there’s always room for a stack, but it’s got to be strategic.

Not just because you can combine, but because you should if it fits your goals and biology.

Let’s unpack this by spotlighting Gotratix (A-18), one of the most powerful yet overlooked bioregulators for muscle, performance, and recovery.

What is Gotratix?

Gotratix (A-18) is a tissue-specific peptide bioregulator extracted from the triceps muscles of healthy young animals.

These peptides are tiny (less than 5000 Da) and, most importantly, they’re muscle-coded.

When you take Gotratix, those peptides home in on your muscle tissue like guided missiles, normalizing cell metabolism and turning back the clock on your muscle’s ability to repair, grow, and thrive.

Gotratix peptides regulate metabolic processes within your muscle cells, enhance their antioxidant capacity, and actually help buffer the damaging effects of oxidative stress.

Think of it as an internal cleanup crew that keeps your muscles primed and ready, especially during heavy training or periods of increased stress.

Clinical Results

Here’s where things get interesting.

One of the best studies comes out of the St. Petersburg Institute of Bioregulation and Gerontology, where they tracked men in a head-to-head, two-month trial.

You can read the study by clicking here.

Participants in the Gotratix group took 1–2 capsules, 2–3x per day, while the control group just trained as usual.

Researchers tracked five key performance markers: grip strength (right and left hand), standing long jump, step test (endurance), and flexibility.

The results?

The Gotratix group outperformed the control group across the board. Here are the exact numbers:

• Right hand grip strength increased by 12.8%

• Left hand grip strength increased by 14.3%

• Standing long jump improved by 7.4%

• Endurance (step test) increased by 5.5%

• Flexibility shot up by 31.4%

Meanwhile, the control group that trained without Gotratix?

They saw almost no meaningful change.

Just more proof that sometimes, the real breakthrough is in what you add to your protocol, not just how hard you train.

Not only did subjects on Gotratix see stronger, more resilient muscle, but they also reported less fatigue, better energy in training, and notably faster muscle recovery post-exercise.

Critically, no side effects or drug interactions were reported.

This was a clean, well-tolerated addition.

What To Expect

For men, especially those already optimizing with testosterone and HGH/HGH peptides, Gotratix acts as a multiplier for your muscle gains, performance, and post-exercise recovery.

You’ll notice less muscle fatigue, better pumps and endurance during your workouts, and actual improvement in your muscle’s reserve capacity.

For women (yes, this is not just a “bro” supplement), Gotratix offers similar muscle resilience and improved recovery.

For athletic women, peri- or post-menopausal, or anyone who values muscle tone and physical capacity, it can help fight age-related decline, speed post-training repair, and keep you feeling energetic.

Both men and women benefit from the normalization of muscle metabolism and antioxidant defense, two things that slow with age and stress.

And for the older crowd, Gotratix may be one of the most overlooked “sarcopenia fighters” in existence. If you want to age gracefully and actively, this belongs in your rotation.

How Gotratix Stacks

Here’s where we get into real synergy.

Suppose you’re already hormonally optimized, using GPL Man (for the full spectrum of male hormone and prostate support), Thyreogen (for thyroid health), and Testoluten (for testicular health and testosterone regulation).

In that case, Gotratix is your secret weapon for muscle-centric optimization.

Why?

Gotratix actually “tunes up” the muscle at the cellular level, so when you hit the gym, eat your clean diet, and stack the right peptides, your muscle is more receptive to those anabolic and recovery signals.

Think of Gotratix as a molecular “grease” that keeps your muscle-building machinery running smoothly, especially as you push your body and mind to the limit.

And when you combine Gotratix with a peptide like Tesamorelin (one of my all-time favorite GH-releasing peptides) or HGH itself, you get the best of both worlds.

Maximized natural growth hormone release and muscle cells that are genetically and metabolically ready to use it.

Stack Smart

So, should you stack?

For total optimization, absolutely, as long as you’re stacking intentionally and listening to your body.

I like to pair tissue-specific bioregulators (like Gotratix, GPL Man, Thyreogen, and Testoluten) with lifestyle optimization (a clean diet, consistent training, stress management, and the right peptides).

By doing so, you’ll experience a synergy that goes way beyond what you’d get from any single product.

However, don’t just throw everything at the wall.

Monitor your response, keep your protocols clean, and cycle your stacks (e.g., 30 days on, 3–6 months off) to let your biology recalibrate.
