Sourcing & Materials
Sustainable sourcing
We are committed to quality products that are manufactured ethically and sustainably. All of our pieces are traceable throughout the supply chain. We strive to ensure our products contribute to the well-being of people and planet, and our efforts put us on track towards a brighter future.
Ethical labor
Our founders Christina Smith and Clement Savant founded Broadcast to break the norms of the jewelry industry. Cheap, disposable jewelry creates an incentive structure to bid out the work to the cheapest factory available. We need to vote with our dollars for a more equitable world.
Transparent values
We hold true to to who we are. We believe in equality and justice for all, and those beliefs permeate the work that we do and the jewelry we make. Everything we do stands for our values and we try to think, speak, and act in a framework of positive change. Cast out your voice and make a difference.
Recycled Materials
We partner with high quality jewellers who only use recycled gold, AAA-grade gemstones, and ethically sourced diamonds.

Are there any side effects taking this supplement?

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)
