Compound Profiles
CJC-1295 (without DAC)
Short-Acting Growth Hormone Releasing Hormone Analog
Binds GHRH receptors on somatotroph cells in the pituitary gland, stimulating cAMP production and physiological GH pulses. The brief 30-minute half-life allows pulsatile release versus prolonged elevation.
Letrozole
Aromatase Inhibitor | Potent Estrogen Suppression
Letrozole competitively and reversibly binds to the heme group of the aromatase enzyme (cytochrome P450 19A1), inhibiting its catalytic activity with greater potency than any other commercially available aromatase inhibitor. Aromatase catalyzes the final step in estrogen biosynthesis, converting testosterone to estradiol and androstenedione to estrone in peripheral tissues including adipose, muscle, liver, and brain.
