Libido Drive Capsules
Capsule form — store in a cool, dry place. Libido Drive combines five individually documented research compounds — PT-141, Oxytocin, Kisspeptin, VIP, and N-Acetyl L-Tyrosine — each studied in its own body of published research for interaction with CNS and endocrine signaling pathways. Supplied at research-grade purity for laboratory use only.

Libido Drive Capsules combine five individually documented research compounds — PT-141 (Bremelanotide), Oxytocin, Kisspeptin, VIP (Vasoactive Intestinal Peptide), and N-Acetyl L-Tyrosine — each studied in its own body of published literature for interaction with central-nervous-system and endocrine-signaling pathways relevant to arousal- and bonding-related research models. Researchers combine compounds such as these to study multiple, overlapping signaling pathways in parallel; the summary below describes each component’s own published research individually. No combined-formulation study of this specific blend is described or implied.
What is in Libido Drive Capsules?
PT-141 (Bremelanotide)
PT-141 is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH), acting as a melanocortin-receptor agonist with reported affinity for MC4R. Research has examined its association with centrally-mediated sexual-arousal pathways in animal and clinical study models — a mechanism study authors distinguish from peripheral vascular mechanisms such as PDE5 inhibition. This research base contributed to an FDA-approved prescription product for a specific clinical indication in premenopausal women, a use distinct from, and not implied by, this product’s research-use-only status.
Oxytocin
Oxytocin is a naturally occurring hypothalamic neuropeptide/hormone, most established in the literature for its role in uterine contraction and lactation let-down, and separately studied in behavioral neuroscience research for its association with social bonding, trust-related behavior, and affiliative responses in tested human and animal models.
Kisspeptin
Kisspeptin is a neuropeptide central to reproductive-endocrine research, reported to regulate pulsatile GnRH and downstream LH release via the hypothalamic-pituitary-gonadal axis in tested models. Separately, human neuroimaging research has examined kisspeptin’s association with brain-activity measures in regions linked to sexual and emotional processing.
VIP (Vasoactive Intestinal Peptide)
VIP is a 28-amino-acid neuropeptide widely distributed in the gut, brain, and peripheral nerve endings, studied broadly for its vasodilatory and neuromodulatory signaling. Within genital-tissue research specifically, VIP has been examined (including in combination with other vasoactive agents in non-U.S. clinical formulations) for its association with smooth-muscle relaxation and blood-flow measures in tested models.
N-Acetyl L-Tyrosine
N-Acetyl L-Tyrosine is an acetylated derivative of the amino acid tyrosine, formulated for improved aqueous solubility relative to free tyrosine. Tyrosine is the metabolic precursor to catecholamines (dopamine and norepinephrine), and research has examined tyrosine/N-Acetyl L-Tyrosine supplementation for its association with catecholamine-dependent cognitive and stress-response performance measures in tested models.

Research Applications
Central Arousal & Neuroendocrine Signaling Research (PT-141, Kisspeptin, Oxytocin)
Each of these three compounds has been individually studied for interaction with central-nervous-system and hypothalamic-pituitary signaling pathways relevant to arousal-, bonding-, and reproductive-axis-related measures in tested animal and human research models. Researchers combine peptides with overlapping but distinct proposed mechanisms — melanocortin-receptor signaling for PT-141, GnRH-axis regulation for Kisspeptin, and bonding-related neuropeptide signaling for Oxytocin — to study multiple pathways in parallel; this is a research-design rationale, not evidence of a validated combined effect.
Peripheral Vascular & Metabolic-Precursor Research (VIP, N-Acetyl L-Tyrosine)
VIP’s vasodilatory signaling and N-Acetyl L-Tyrosine’s role as a catecholamine precursor represent separate, independently studied research areas relevant to peripheral blood-flow and neurotransmitter-synthesis research, respectively.
