SLEEP · 10 WEEKS · LOT #PK-2642

Vesper.

Deep sleep, growth hormone restoration, overnight recovery.

A 10-week recovery arc built on CJC-1295, a long-acting growth hormone releasing hormone (GHRH) analog. Vesper restores the natural pulsatile GH rhythm that drives slow-wave sleep, tissue repair, and overnight metabolic clearance.

· THE COMPOUND

What's in the vial.

01
CJC-1295
GHRH analog
DESCRIPTION

A 30-amino-acid GHRH analog, optionally with DAC (Drug Affinity Complex) for extended half-life. Administered subcutaneously in the evening.

MECHANISM

Binds the GHRH receptor on the anterior pituitary, stimulating endogenous GH release in physiologic pulses. Preserves the negative feedback loop, unlike exogenous GH.

· OUTCOMES

What patients report.

  • Increased slow-wave (deep) sleep duration
  • Improved overnight tissue and tendon repair
  • Restored IGF-1 toward youthful range
  • Better body composition with consistent training
  • Morning HRV and readiness improvements
· WHO IT'S FOR

Designed for.

  • Athletes managing chronic training load
  • Adults with poor sleep architecture (low N3)
  • Anyone supporting GH/IGF-1 axis post-40
