Synthesis by SwissRX is a revolutionary peptide-based supplement containing PeptiStrong®, a breakthrough ingredient derived from the protein of fava beans.

Unlike most peptides that require injections or prescriptions, Synthesis is oral, 100% sports-legal and works through your body’s existing pathways to enhance strength, accelerate recovery and improve body composition.

This peptide acts as a messenger in your body, telling it to do more of what it naturally does – build muscle and recover faster. Discovered by an Irish biotech company using advanced AI technology, PeptiStrong® has shown remarkable results in human clinical trials.

Why Use Synthesis

You use Synthesis to:

Build strength faster - Clinical trials show it delivers and rebuilds muscle faster than whey protein alone.
Recover more quickly - Achieve 54% faster recovery compared to placebo.
Reduce fatigue - Experience a 47% reduction in training fatigue.

We have found that this supplement is particularly effective for athletes over 35, when recovery and strength gains become more challenging.

Our founder transformed his physique at 50 – dropping 8% body fat while increasing strength and running performance. He’s experienced firsthand how Synthesis can help overcome age-related training plateaus.

Unlike most supplements with marginal benefits, Synthesis delivers what we call an “acute response” – you’ll know it’s working through noticeably improved recovery within 2 weeks and, in our case, breakthrough strength gains within 4-8 weeks when combined with intense training.

How/When Do You Use Synthesis

Dosage: Take 4 capsules daily, ideally in the morning with or without food.

Consistency: For optimal results, take Synthesis consistently for at least 60 days alongside your regular training. This isn’t a “magic pill” – it’s a tool that amplifies the results of the hard work you’re already putting in.

What to Expect

Weeks 1-2 – Noticeably improved recovery between training sessions
Weeks 3-6 – Breaking through strength plateaus and improving performance
By 60 days – Visible changes in body composition and significant performance improvements

Synthesis works best when combined with regular, challenging exercise. It’s not a replacement for training – you still need to put in the work – but it significantly enhances the results of that work, especially as you age.

How It Works

Synthesis works through multiple pathways to enhance strength and recovery:

Activates mTOR pathway – The master regulator of muscle growth, stimulating protein synthesis
Reduces catabolic enzymes – Lowers the production of enzymes that break down muscle protein after hard training, preserving more of your gains
Moderates inflammation – Blunts the post-exercise inflammation spike, allowing for 54% faster recovery over placebo
Enhances mitochondrial function - Increases the size and energy production of mitochondria, reducing fatigue by 47%

Synthesis tells your body to build muscle faster while simultaneously telling it to break down less muscle after training. The result is accelerated gains and improved recovery – even as you age.

“I don’t share new supplements with you unless they are truly exceptional and I’ve proven they work to myself. Synthesis shocked me with what it delivered – strength gains I hadn’t seen in years, 8% body fat reduction, and performance I didn’t think was possible at 50. I'm confident it will do the same for you.” - Matt, Founder of The Feed
