Peptides vs SARMs: What’s the Difference?

The Ultimate Guide for Gym-Goers, Biohackers & Bodybuilders
In the world of performance enhancement, two names dominate the conversation: Peptides and SARMs.
Whether you're chasing muscle growth, faster recovery, or fat loss, it’s important to understand what these compounds are, how they work, and which one fits your goals best.
This blog dives deep into the differences — and helps you shop the highest quality peptides and SARMs in the UK.
💡 What Are Peptides?
Peptides are short chains of amino acids, naturally occurring in the body. They act as messengers that stimulate a variety of biological responses like tissue repair, hormone release, and growth.
Popular peptides include:
👉 IGF-1 LR3 1mg by Nordic Labs – Powerful for lean muscle growth
👉 TB500 10mg by Nordic Labs – Recovery and soft tissue regeneration
👉 BPC-157 5mg by Nordic Labs – Joint, gut, and injury repair
👉 AOD9604 2mg by Nordic Labs – Targeted fat loss peptide
These peptides support natural processes, helping your body work smarter — not harder.
⚙️ What Are SARMs?
SARMs (Selective Androgen Receptor Modulators) are synthetic compounds that bind to androgen receptors in the muscles and bones — mimicking the anabolic effects of testosterone without the harsh side effects of steroids.
Top SARMs (available at Just SARMs UK) include:
💥 RAD-140 (Testolone) – Maximum muscle-building
💥 Ostarine (MK-2866) – Ideal for beginners & body recomposition
💥 YK-11 – Myostatin inhibitor for extreme hypertrophy
⚖️ Peptides vs SARMs: Key Differences
| Feature | Peptides | SARMs |
|---|---|---|
| How They Work | Mimic hormones/signals like GH, IGF-1 | Bind to androgen receptors |
| Muscle Growth | Moderate to High | High to Very High |
| Fat Loss | Very Effective (AOD9604, Fragment 176-191) | Effective (Ostarine, Cardarine) |
| Healing/Recovery | Excellent (TB500, BPC-157) | Limited |
| Side Effects | Very low | Can cause suppression or aggression |
| Delivery | Injectable or nasal spray | Oral capsules |
| Legality | Legal for research | Legal for research |
🏋️ Which One Should You Choose?
For Muscle Growth
Stack IGF-1 LR3 with RAD-140 for massive lean gains.
For Fat Loss
Use AOD9604 or Fragment 176-191 to melt stubborn fat, or go with Ostarine for a cut phase.
For Injury & Recovery
Hands down, peptides like BPC-157 and TB500 outperform SARMs.

✅ Final Word
Peptides are great for recovery, long-term muscle growth, and natural fat loss.
SARMs are ideal for short-term performance spikes and aggressive physique changes.
Both have their place. And when used smartly — they can work synergistically.
