KissPeptin-10
A short form of kisspeptin, the hormone that sits at the top of your reproductive hormone system. It directly tells the brain to release the signals that kick off the whole chain — FSH, LH, and ultimately testosterone or estrogen. Researchers are studying it as a possible alternative to other fertility hormones, with potentially fewer issues of the body 'getting used to' it.

Mechanism of Action
KissPeptin-10 is the shortest bioactive fragment of the kisspeptin family, derived from the 145-amino-acid precursor protein encoded by the KISS1 gene. The kisspeptin system was identified as the master upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis when loss-of-function mutations in its receptor (KISS1R/GPR54) were found to cause hypogonadotropic hypogonadism — complete failure of puberty and reproductive function.
Kisspeptin-10 binds to KISS1R (formerly GPR54), a Gq/11-coupled GPCR expressed predominantly on GnRH neurons in the hypothalamus, specifically in two key nuclei: the arcuate nucleus (ARC) and the anteroventral periventricular nucleus (AVPV). KISS1R activation stimulates phospholipase C, generating IP3 and DAG, which raise intracellular calcium and activate protein kinase C in GnRH neurons. This depolarizes the neurons and triggers GnRH release into the hypophyseal portal system, which then stimulates FSH and LH secretion from anterior pituitary gonadotrophs.
What makes kisspeptin extraordinary is its position at the very apex of the reproductive hormone cascade. It sits upstream of GnRH itself, integrating metabolic, circadian, and hormonal signals to determine when and how strongly GnRH pulses fire. Kisspeptin neurons in the ARC co-express neurokinin B and dynorphin (forming the 'KNDy' neuron population) and function as the GnRH pulse generator — the fundamental oscillator that drives pulsatile reproductive hormone secretion. Estradiol and testosterone feed back to kisspeptin neurons (not directly to GnRH neurons) to regulate the HPG axis, making kisspeptin the integration point for sex steroid feedback. This upstream position makes kisspeptin-10 a uniquely powerful tool for stimulating the entire reproductive axis from the top, with clinical potential for triggering ovulation in IVF protocols and restoring fertility in functional hypogonadism.

Alprostadil
A medication that treats erectile dysfunction by relaxing the blood vessels in the penis, allowing blood to flow in and create an erection. Unlike pills that require arousal to work, this works directly at the injection or application site — you don't need to be in the mood. Available as an injection into the penis or as a small pellet inserted into the urethra.
Enclomiphene
A medication that boosts natural testosterone production by blocking estrogen's feedback signal in the brain. Used in men's health clinics as an alternative to testosterone shots that preserves fertility and testicular function. Unlike mixed clomiphene (Clomid), enclomiphene lacks the estrogen-like component (zuclomiphene) that causes many of clomiphene's side effects.
Gonadorelin
A lab-made copy of the hormone your brain naturally releases to tell your body to make reproductive hormones. When given in short pulses (not continuously), it signals the pituitary gland to release hormones that keep the testes working. Used for fertility treatment, diagnosing hormone problems, and keeping testicular function and sperm production going during testosterone therapy.
HCG
A hormone your body makes during pregnancy that acts like the hormone that tells the testes to produce testosterone and sperm. Used to treat low testosterone and fertility issues. Commonly used by men on testosterone therapy to keep their testes working and sperm production going, and by bodybuilders after steroid cycles to help their hormones recover.
