Hormone
Chemical messenger made by the body
A hormone is a chemical messenger produced by one part of the body and carried by the blood to act on distant tissues. Hormones help control growth, metabolism, reproduction, appetite, and stress responses. Many research peptides are studied because they copy or influence the action of natural hormones.
Used in 19 research peptides

- PerformanceCJC-1295Pairs with Ipamorelin for sustained growth hormone spikes, ideal for body comp tweaks.
- PerformanceSermorelinMimics natural GH pulses to build lean mass and improve sleep/recovery.
- PerformanceMK-677 (Ibutamoren)Oral GH secretagogue that cranks appetite, muscle preservation, and bone density.
- PerformanceHexarelinPotent GH stimulator for quick strength gains and vascularity in bodybuilders.

- PerformanceHGHGrowth Hormone Essentials.
- PerformanceIGF-1 LR3Growth Mediator.
- MetabolicRetatrutideThe 'Godzilla' of weight loss; a triple-hormone agonist for unprecedented fat loss and metabolic health.
- PerformanceGHRP-1First-generation growth hormone-releasing hexapeptide; precursor to GHRP-2/-6.
- LongevityKlotho (alpha-Klotho)Anti-aging hormone; soluble klotho boosts cognition and modulates phosphate/FGF23 axis.
- PerformanceGHRH (Growth Hormone-Releasing Hormone)Native 44-aa hypothalamic GHRH; parent molecule of sermorelin, CJC-1295, and tesamorelin.
- PerformanceHCG (Human Chorionic Gonadotropin)Glycoprotein hormone with LH-mimetic activity that stimulates gonadal steroidogenesis; FDA-approved for cryptorchidism, select male hypogonadotropic hypogonadism, and ovulation induction.
- OtherOxytocinNine-amino-acid neuropeptide hormone; FDA-approved as an injectable for obstetric use, and studied off-label as an intranasal agent for social, anxiety, and sexual-health applications with mixed results.
- TRTDHEA (Prasterone)DHEA (dehydroepiandrosterone; prasterone) is an endogenous adrenal steroid that serves as a precursor to androgens and estrogens. The vaginal insert formulation (Intrarosa) is FDA-approved for dyspareunia due to menopause; oral DHEA products are sold as dietary supplements and do not have an FDA drug approval for systemic hormone replacement.
- TRTPregnenolonePregnenolone is an endogenous neurosteroid and the first committed steroid produced from cholesterol. It is not FDA-approved as a drug and is available as a dietary supplement or through compounding.
- TRTTamoxifenTamoxifen (Nolvadex) is a nonsteroidal SERM and the primary approved endocrine therapy for hormone receptor-positive breast cancer. Its use in males during or after testosterone therapy to manage gynecomastia or restore the hypothalamic-pituitary axis is off-label.
