HOW We’re different
Go back in time, naturally
Testosterone powers more than muscle—it drives energy, focus, libido, and health. Since the ‘90s, levels have dropped. This supplement helps bring it back, so you feel sharper, stronger, and fully you.
No Dangerous Hormones
Boosts natural testosterone safely—no hormones, no injections, just energy, focus, and vitality.
No Artificial Junk Added
21 Again Rewind uses only premium natural ingredients from around the world, formulated and packaged in the U.S.A.
We Use Clinical Level Doses
Our supplement delivers twice the dose of leading brands—unlike others with weak formulas that fall short. Get real results.
Ours is Phd Formulated
After struggling with low T and failed boosters, our PhD Food Scientist spent three years creating a formula that actually works.

Phd food scientist, jarret
I’m Jarret Stopforth, Co-founder of 21 Again. I started developing 21 Again after turning 40, when I experienced a noticeable decline in energy, drive, and libido, along with weight gain. Frustrated with the lack of results from popular “natural testosterone boosters,” I dedicated three years to researching and testing various plant-based ingredients and combinations.
Finally, I created a formula that made a significant difference. After 30 days, I felt revitalized with improved energy, reduced body fat, and a renewed sense of vitality. Sharing it with friends confirmed its impact, inspiring the launch of 21 Again. Our mission is to offer a scientifically-proven supplement that helps men regain their youthful energy, drive, and vigor. Basically—to feel 21 Again.

Frequently asked questions
What is 21 Again Rewind?
21Again Rewind is a natural testosterone support supplement designed to help men feel energized, focused, and vital again. It’s not a synthetic hormone— it's a powerful blend of botanicals and nutrients that support your body's own ability to produce testosterone naturally.
What is your return policy?
We stand behind the quality of our product and your satisfaction is our priority. If you're not completely satisfied with your purchase, you can return it within 30 days for a full refund—no questions asked. To initiate a return, contact our support team with your order details and we’ll guide you through the simple process.
How often should I take the pills?
For optimal results, take your capsules daily, preferably with food. Consistency is key— Do not exceed the recommended dose unless instructed by your physician.
Are there any side effects taking this supplement?
Most 21 Again users report no negative side effects. The ingredients are all-natural, clinically studied, and generally well-tolerated. That said, if you’re taking medications or have underlying health conditions, it’s best to check with your doctor.
Will it make me angry?
No. In fact, many users report feeling calmer and more in control. Balanced testosterone tends to improve mood stability, not worsen it.
What age is 21 Again recommended for?
Typically men over 30 start to notice a dip in energy, strength, and libido—that’s when this can really help. But men in their 40s, 50s, and beyond often get the most noticeable benefits.
What's the difference between 21 Again and TRT?
TRT (Testosterone Replacement Therapy) involves injecting synthetic testosterone, which can shut down your body’s own production. 21Again Rewind works with your body, encouraging natural production and maintaining balance without the risks or side effects of TRT.
