Researchers are increasingly looking into the question of kisspeptin-10 dosage, with many looking for guidelines on how to use this peptide as an adjunct to testosterone replacement therapy. 

Kisspeptin-10 is key to hormone signaling during puberty, as well as facilitating reproductive processes. Specifically, the peptide is known to: 

  • Stimulate the pituitary hormones LH and FSH 
  • Regulate emotions and mood 
  • Positively impact metabolism 

In this kisspeptin-10 dosage calculator and guide, we discuss the potential benefits and side effects of the peptide, before going over a sample dosing protocol. 

We close by recommending a peptide vendor that sells USA-produced kisspeptin-10 for research purposes.

What is Kisspeptin-10?

Naturally produced in the hypothalamus, the neuropeptide kisspeptin is one of the most crucial components of the reproductive system, as it is largely responsible for the regulation of downstream reproductive hormone release [1].

Kisspeptin-10 is an analog of kisspeptin (metastin) that works by signaling nerve terminals of GnRH neurons to regulate GnRH release, pulsatility, and discharge, in addition to serotonin. The activation of endogenous gonadotropin-releasing hormone (GnRH) in the pituitary gland then leads to elevated production of LH and FSH.

By consequence, kisspeptin-10 injections have been shown to increase testosterone levels in men, in addition to improving fertility [2, 3]. Studies have shown that the absence of kisspeptin signaling in rodents and humans can lead to hypogonadotropic hypogonadism (HH) and difficulty in sexual maturation [2].

Aside from the important role kisspeptin plays in the regulation of reproductive functions, recent studies have shown that it also contributes to controlling metabolism and mood [4]. One study has shown that kisspeptin administration can substantially decrease central levels of the key inhibitory neurotransmitter GABA in the human brain, leading to changes in how the body reacts to anxiety, stress, and fear [1].

Kisspeptin-10 Benefits

Kisspeptin-10 is most noted for its benefits relative to human reproduction, but it has also been shown to positively affect metabolism, mood, and behavior.

Kisspeptin-10 may facilitate weight loss

Kisspeptin works within the same hormone feedback loop as does human chorionic gonadotropin: the critical hypothalamic-pituitary-gonadal (HPG) axis. The potential effect on weight loss is achieved through the boosting of luteinizing hormone and adiponectin.

The increase in adiponectin in turn reduces blood glucose, leading to a faster breakdown of fatty acids. The activation of adiponectin can thus help with the management of weight and weight-related disorders [5].

A 2010 study on male rhesus monkeys found that kisspeptin-10 administration significantly increased mean plasma adiponectin levels under fed and 24-hour fasting conditions, as compared to pretreatment or vehicle-treatment levels [5].

Kisspeptin-10 may help reduce anxiety

The kisspeptin system is also believed to impact hormonal aspects of anxiety and stress. Specifically, kisspeptin-10 has been shown in zebrafish to reduce fear response through serotonergic pathways, which directly affects reproduction and conservation [6].

In addition, kisspeptin-10 has been shown to regulate nitric oxide, neurokinin B, dynorphin, glutamate, glutamate receptors, as well as cocaine and amphetamine-responsive transcript signals. Kisspeptin signaling can thus stimulate various pathways in the body to produce changes in emotions and sexual cognition [7].

Kisspeptin-10 as a testosterone therapy adjunct

Kisspeptin-10 has been posited as an alternative to hCG in subjects undergoing testosterone therapy, as it allows for the optimization of FSH and LH levels, and so serves to stabilize the HPG hormonal feedback loop. Kisspeptin and its receptor are present in human spermatozoa and modulate key parameters of sperm function [6, 7].

Studies have shown kisspeptin-10 to contribute positively to the effects of reproductive hormones. One such study found that injecting kisspeptin-10 into healthy males increased LH production, LH pulse frequency and size, and testosterone [8].

In addition, kisspeptin causes a transient increase in the percentage of a grade spermatozoa. In males, circulating kisspeptin levels have been found to be higher in fertile men than infertile men [9].

Kisspeptin for enhanced memory and mood

Rodent research suggests that administration of kissorphin, a derivative of kisspeptin-10, can prevent spatial memory impairments, and aso reverse learning deficits induced by ethanol administration. It was found that kissorphin given during withdrawal from “binge-like” ethanol administration reduced cognitive flexibility impairment in ethanol-withdrawal rats [10].

Additional rodent studies have shown that kisspeptin can produce antidepressant-like effects [11]. Namely, peripheral kisspeptin administration enhances frontal brain activity in response to negative pictures and reduces negative mood [11, 12].

Furthermore, a study conducted on 29 healthy heterosexual young men found that kisspeptin enhances limbic brain activity, is correlated with “psychometric measures of reward, drive, mood, and sexual aversion.” The study also found that kisspeptin administration attenuated negative mood [12].

Kisspeptin-10 Side Effects

Studies have shown that kisspeptin may be administered safely to subjects without serious adverse effects [8, 13]. In healthy human volunteers, intravenous administration of kisspeptin effectively increases LH, FSH, and testosterone without side effects in both males and females [13].

A study investigating the effect of kisspeptin-10 on GnRH recorded that a number of vital signs remained stable in test subjects throughout the study period. The signs included blood pressure, heart rate, peripheral oxygenation, liver function, renal function, hemoglobin, mean corpuscular volume, and electrolytes [8].

However, one study has found that mice injected with a pharmacological dose of kisspeptin-10 experienced a handful of side effects, namely altered metabolism through suppressed food intake, meal size, and eating rate. These findings suggest that kisspeptin-10 could affect metabolism and energy homeostasis by reducing appetite and therefore food consumption [14].

In another rodent study, researchers administered a range of kisspeptin-10 doses (1 μg, 1 ηg, and 10 ρg) to prepubertal male rats twice daily, noting degeneration of seminiferous tubules, multinucleated giant cell formation, intratubular vacuolization, widened lumen and deshaped germ cells. The researchers concluded that long-term kisspeptin-10 administration negatively affects gonadal maturation in prepubertal testes [15].

Kisspeptin-10 Dosage Calculator and Guide

Below we provide researchers with information on how kisspeptin-10 may be administered to test subjects.

Kisspeptin-10 Administration Notes

  • The typical method of administering kisspeptin-10 is via intravenous infusion. Yet, the peptide can also be administered as a subcutaneous injection. Subcutaneous injections are often the preferred method in research settings due to ease of use and safety.
  • The effects of kisspeptin-10 may typically be observed for twenty four hours after the initial injection. Peak concentrations of LH and testosterone reach 45-60 minutes after administration for all dosages tested [8].
  • Researchers should note that kisspeptin-10 may produce greater effects when administered to subjects in a fasted state. One study found that fed subjects demonstrated a 9 to 10 fold increase in LH concentrations in serum 15 minutes following kisspeptin injection. In contrast, the researchers observed a 50- to 60-fold increase in LH release in fasted subjects [16].
  • Studies report that LH response is highest after administering a one-time dose of 1mcg/kg of body weight, compared to higher or lower doses of kisspeptin-10 [8]. Therefore, subjects should be administered doses of around 100mcg for achieving maximum effectiveness.
  • Studies report that another kisspeptin analog (kisspeptin-54) leads to desensitization when administered daily, but not when administered bi-weekly in female subjects. Desensitization of the receptors may lead to the opposite effect and reduction of LH levels. Studies in male subjects do not report desensitization after almost 24 hour infusion of kisspeptin-10. Nevertheless, researchers are advised against repeated daily dosing of the peptide. Specific dosing regimes should be determined based on individual LH and FSH response [17].

Sample Kisspeptin-10 Dosage Protocol for Testicular Atrophy Research

For reference purposes, here is a sample kisspeptin-10 protocol that researchers may administer to achieve the prevention of testicular atrophy in subjects undergoing testosterone therapy:

  • Dosage: One subcutaneous injection of 100-200mcg of kisspeptin-10.
  • Frequency: Do not administer daily. Administer as a single subcutaneous injection. Repeated use carries unknown risk for desensitization, which may lead to the opposite effect—suppression of LH and testosterone synthesis.
  • Study Duration: Administer as an adjunct to testosterone therapy.
  • Notes: To determine appropriate dosing schedule for a given subject, perform blood work to assess FSH and LH levels.
