In the world of performance enhancement and weight loss, HGH Fragment 176-191 has gained a reputation as a “fat-melting” peptide. Popular on forums, social media, and in bodybuilding circles, it’s marketed as a safer, targeted alternative to full human growth hormone (HGH).

But does it really work? Is it legal? And is it worth the hype?

This article breaks down the science, dispels the myths, and explains how it compares to safer, evidence-based fat-loss strategies.

Discover the essential guide to knee replacement rehabilitation. From pre-surgery preparation to recovery exercises and long-term strategies, this step-by-step plan supports both total and partial knee replacements for lasting mobility and strength.

Human chorionic gonadotropin (HCG) is a glycoprotein hormone naturally produced during pregnancy. It functions much like luteinizing hormone (LH), signalling the ovaries or testes to produce reproductive hormones. The “5000 IU” simply refers to the vial’s concentration — a high-dose preparation often prescribed for fertility and hormone optimisation.

Pushing yourself in training is essential for growth—but there’s a fine line between optimal challenge and destructive overload.

Overtraining syndrome (OTS) can derail months of progress, increase injury risk, and leave athletes feeling constantly fatigued and demotivated. It’s common in competitive athletes, CrossFitters, and runners who believe “more is better.”

In this article, we’ll break down what overtraining really is, how to recognise it early, and—most importantly—how to prevent and reverse it using proven recovery and rehabilitation strategies.

When it comes to injury recovery and performance enhancement, few topics stir as much interest—and controversy—as BPC-157 and TB-500. Branded by enthusiasts as “healing peptides,” these compounds are increasingly discussed in athletic, rehabilitation, and biohacking circles.

But do they really work? How are they dosed? And most importantly—are they safe and legal?

This article takes a science-based look at both peptides, cutting through the hype to explore what the research actually says, who might benefit, and where the risks lie.

Dartmouth local Cathy Campos, living with MS and awaiting knee replacement surgery, transformed her strength and confidence in just six sessions at Poseidon Performance—progressing from lifting a 12 kg kettlebell to 45 kg on the trap-bar while improving posture, energy, and whole-body stability.

Still feeling tight no matter how much you stretch?

You’re not alone—and the problem likely isn’t flexibility. Most muscle tightness is your nervous system protecting an underprepared area, not a sign you need more stretching.

In this blog, we break down why tightness is a sensation, not a diagnosis—and why strength, control, and load-specific training are the real long-term fix.

We don’t use weight machines at Poseidon — because they don’t build real strength. Machines follow fixed paths designed for the average person. We coach movement that’s tailored to you — building strength, stability, and resilience that lasts.

Struggling with fatigue, stubborn weight, or rising blood sugar despite staying active? The missing piece might be muscle. At Poseidon Performance in Dartmouth, we help adults over 45 reverse metabolic dysfunction through smart, evidence-based strength training. Discover why building strength—not chasing cardio—is the key to long-term health, energy, and resilience.

Bone loss affects nearly half of women over 50—but it doesn’t have to be inevitable. Strength training just 2–3 times per week can cut your fracture risk in half and help preserve independence, mobility, and confidence well into your 70s and beyond. Here’s how to futureproof your body, starting now.

A groundbreaking 2025 review has confirmed what many strength coaches already suspected: resistance training during pregnancy is not only safe—it’s incredibly beneficial. From reducing pain and fatigue to lowering the risk of reproductive complications, strength training is proving to be one of the most powerful tools for a healthier pregnancy.

Reformer Pilates isn’t enough—here’s why healthy, injury-free adults should look elsewhere if they’re training for real strength, resilience, and long-term independence.

Tendon rehab isn’t about rest — it’s about smart, progressive loading. This blog breaks down the most common tendon issues, evidence-based rehab strategies, and why passive treatments alone often fail. If you’ve been stuck with stubborn tendon pain, this is your roadmap to recovery.
