There is no denying the struggle when it comes to muscle mass maintenance, strength building, and recovery time with age. However, this new peptide is rewriting the script and unlocking progress that I thought was impossible.
I found a new product that has completely changed my ability to build strength, even at the tender age of 50 where this is supposed to be much harder. Not only did I gain significantly more power, but it also dramatically improved muscle recovery after hard workouts, allowing me to string together much more consistent training.
When we first launched Synthesis in June of 2025, I speculated it would be a top 3 product of 2025. Well, it finished up the year as the #1 Most Repurchased Product We've Launched.
Why You Should Add This to Your Routine:
Last year, I turned the dreaded 50.
I had one goal, which was to get into the best shape of my life. But between work, life drama, and well, being almost "middle age", that was proving harder than I expected. I was doing the training, but not really seeing the results.
Then in December, everything changed. I was doing basically the same training, but all of a sudden I was getting way different results. I was able to lift more than ever before. Breaking through limits I had been at for years.
It wasn't just lifting, I started pushing the paddle on the treadmill forward more and more until I went from intervals at a mid-7.5-minute mile pace to a low 6-minute mile pace (and I'm hardly built to be a runner).
The only difference is a new peptide-based supplement I started testing, now available as Synthesis by SwissRX, and it completely changed how I was able to gain strength, improve my power in running and cycling, and create way more lean body composition.
The key ingredient comes from an Irish biotech company that discovered a novel, natural, and fully sports-legal network of peptides—derived from fava bean protein. What stood out was the data: mostly human clinical trials, with results that were almost too good to believe:
4x faster muscle synthesis than with traditional whey protein
54% faster recovery over placebo
47% reduction in fatigue
Significant muscle growth without changing training volume
The future of supplements is purpose-built, bio-engineered, and has what I call an "acute response," meaning they have a very clear method of action in your body and you absolutely know they are working. Synthesis is a great example of this.
From Skeptic to Believer
After two weeks, I was forced to reconsider everything I thought I knew about building strength, especially over the age of 40, let alone 50. Here was my experience last year:
Started in December (Week 1-2): Recovery between sessions noticeably improved
Mid-December: Broke through strength plateaus I'd been stuck at forever
January: Stopped taking it for 4 weeks as a test – recovery plummeted, training suffered
February-March: Resumed – benefits returned within weeks
April: Completed my first HYROX in the top 1% of run times – at 50 years old
What Makes This Different
It's called Synthesis by SwissRX, and it contains Peptistrong – a network of peptides:
It's completely natural, derived from fava bean protein.
It's oral, not injected like most peptides
It's 100% sports-legal
It works through your body's existing pathways
The science is revolutionary but straightforward:
Synthesis activates your mTOR pathway (the master regulator of muscle growth) while simultaneously reducing the enzyme that breaks down muscle protein after training.
The result: your body builds muscle faster while losing less – even as you age. It also reduces recovery time between sessions by reducing the inflammation spike you get after a hard workout.
Take 4 capsules in the morning. That's it. Within 2-4 weeks, you'll notice the difference. By 60 days, people will ask what you're doing differently.
Now you still have to train and train hard. It's not a sit-on-the-couch-and-get-strong pill. But the results you will get from your training shocked me, and I bet they will shock you too.
I'll pay for it if it doesn't work for you.
Try it for two months. If you don't experience better recovery, increased strength, or improved body composition, I'll refund your purchase – no questions asked.
But based on my experience and the clinical data, and as long as you are willing to push your training a bit, I'm betting you'll be reordering before those 60 days are up.
Q & A On Peptides
Q: What is a Peptide?
Peptides are small proteins that act like messengers in your body, telling it to do more or less of what it's already doing naturally. Normally, many peptides require a prescription and need to be injected. Synthesis works as an oral supplement without a prescription.
Q: What does Synthesis actually do?
Signals your mTOR pathway to accelerate muscle protein synthesis
Reduces the enzyme that breaks down muscle protein after hard training
Lowers sports-induced inflammation for 54% faster recovery over placebo
Increases mitochondrial size and energy production, reducing fatigue by 47%
Q: Is Synthesis a fuel source/protein?
Synthesis is a network of natural peptides that signal your body's natural processes. Peptides exist in our bodies and tell our bodies to increase or decrease existing natural processes. It is not a fuel source like whey protein—it's telling your body to increase protein synthesis while also lowering the production of an enzyme that breaks down muscle after hard training.
Q: Aren't peptides dangerous / not legal in sports?
Certain synthetic and injectable peptides may or may not be dangerous. Synthesis is a network of peptides from a natural food source, so no more dangerous than eating fava beans. Since it is from a natural source and not injected, it is legal in all sports.
Q: How long should I take it?
For best 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.
Q: What if I'm taking a GLP-1?
One of the side effects of a GLP-1 is the reduced calories means you might loss some muscle mass and strength. The biotech firm has clinical studies underway on the key ingredient in Synthesis to see if it can stop muscle loss for anyone taking a GLP-1. My guess is that it will show a very positive benefit, but we can't say for sure until the clinical trials are complete.
