Blackstone Labs Chosen1 is a powerful 1-Andro prohormone designed for advanced users seeking lean muscle growth, strength gains, and enhanced performance. Featuring a triple-ester blend of 1-DHEA and a liposomal delivery system for optimal absorption, Chosen1 stands out as one of the most bioavailable and effective prohormones on the market.

Q: Do I need a PCT after using Chosen1?
A: Yes. A full PCT like Arimiplex is required following any prohormone cycle to restore natural hormone levels.
Q: Will Chosen1 cause estrogen-related side effects?
A: No, 1-Andro does not convert to estrogen, so side effects like water retention or gynecomastia are unlikely.
Q: Can Chosen1 be stacked with other products?
A: Absolutely. It stacks well with Brutal 4ce, Sustanon 250, or Androdiol, and can be used alongside stimulant-based pre-workouts like Mesomorph.
