Showing 32 peptides in Hormone Optimization
Peptide Blend
A compounded blend combining ipamorelin (ghrelin receptor agonist) with tesamorelin (GHRH analogue) for synergistic GH secretion with tesamorelin's additional visceral fat-reducing properties.
Growth Hormone Secretagogue
A research peptide blend formulated to investigate growth hormone axis modulation through combined GHRH and ghrelin receptor pathways.
Growth Hormone Releasing Hormone Analog
Tesamorelin is a synthetic research peptide and stabilized analog of growth hormone–releasing hormone (GHRH).
Peptide Blend
A triple-peptide compounded blend combining AOD-9604 (fat-mobilizing GH fragment) with CJC-1295 and ipamorelin for comprehensive GH-axis optimization with targeted lipolysis.
Growth Hormone Releasing Hormone
FDA-approved GHRH analog for growth hormone deficiency.
Growth Hormone Secretagogue
Combination growth hormone secretagogue therapy.
Growth Hormone
HGH 191AA refers to recombinant human growth hormone (somatropin) with the full 191 amino acid sequence. It is FDA-approved under multiple brand names for growth hormone deficiency, Turner syndrome, and other specific indications.
Growth Hormone Releasing Peptide
A selective growth hormone-releasing peptide with minimal side effects.
Growth Hormone Releasing Hormone Analog
A growth hormone-releasing hormone analog that increases GH and IGF-1 levels.
Growth Hormone Releasing Peptide
Potent GHRP that stimulates GH secretion for muscle recovery and anti-aging.
Growth Hormone Releasing Peptide
Growth hormone-releasing peptide that stimulates appetite and GH secretion.
Peptide Blend
Adamax is a branded compounded peptide blend typically combining CJC-1295 DAC, Ipamorelin, and BPC-157, formulated to simultaneously stimulate growth hormone secretion, promote tissue repair, and support recovery — often available as a single reconstitution vial.
Russian Bioregulator Peptide
Testagen is a synthetic tetrapeptide bioregulator (Lys-Asp-Glu-Ala) developed for testicular tissue support and male reproductive system restoration, studied for effects on Leydig and Sertoli cell function in aging males.
Peptide Blend
The most widely used compounded GH peptide combination, pairing modified GRF 1-29 (CJC-1295 without DAC) with ipamorelin for a clean, pulsatile GH release that mimics natural secretory patterns.
Growth Hormone Secretagogue
GHRP-2 is a synthetic hexapeptide that functions as a potent growth hormone secretagogue.
Growth Hormone Secretagogue
CJC-1295 (no DAC) and Ipamorelin is a research peptide blend combining two mechanistically distinct secretagogues that act synergistically on the growth hormone axis.
Peptide Blend
A compounded blend of CJC-1295 (GHRH analogue) and GHRP-2 (ghrelin receptor agonist) for synergistic growth hormone stimulation through complementary receptor pathways.
Bioregulator
Ovagen is a peptide bioregulator derived from liver tissue extracts used in studies of detoxification and cellular regeneration.
IGF-1 Analogue
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified 83-amino acid analogue of IGF-1 with an N-terminal arginine extension and Glu3→Arg3 substitution, conferring a half-life of approximately 20–30 hours versus 12–15 minutes for native IGF-1.
IGF-1 Splice Variant
Mechano Growth Factor (MGF) is an alternatively spliced form of the IGF-1 gene expressed locally in muscle tissue following mechanical stretch or damage, promoting satellite cell activation and muscle repair.
Follistatin 315 is a research peptide isoform of the follistatin protein that binds and neutralizes activins and myostatin.
Follistatin is a multifunctional glycoprotein studied for its role in growth factor signaling networks.
Follistatin 344 is a research peptide variant known to bind myostatin and activin-A, modulating TGF-β signaling.
Gonadotropin
Human chorionic gonadotropin (HCG) is an LH-analogous glycoprotein hormone produced during pregnancy. In men, it stimulates Leydig cell testosterone production, maintaining testicular size and function during exogenous testosterone therapy.
Neuropeptide
Neuropeptide involved in reproductive hormone regulation and sexual health.
Gonadotropin Mixture
Human menopausal gonadotropin (HMG) is a purified gonadotropin preparation derived from the urine of postmenopausal women, containing both FSH and LH activity. It is used primarily for fertility induction and restoration of spermatogenesis.
Neuropeptide
Oxytocin is a 9-amino acid nonapeptide neuropeptide produced in the hypothalamic paraventricular and supraoptic nuclei, with wide-ranging effects on social bonding, anxiety, pain modulation, inflammation, and uterine/mammary function.
Gonadotropin-Releasing Hormone Analog
Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH).
Hypothalamic regulatory peptide
Thyrotropin releasing hormone (TRH or Protirelin) is a research peptide that modulates pituitary secretion of thyrotropin (TSH) and prolactin.
Gonadotropin-Releasing Hormone
Gonadorelin is a research peptide corresponding to the natural gonadotropin-releasing hormone (GnRH).
Bioregulator
Pancragen is a peptide bioregulator derived from pancreatic tissue extracts studied for its role in modulating endocrine and exocrine gene expression.
Growth Hormone Secretagogue
GHRH is a 44-amino acid hypothalamic research peptide that stimulates growth hormone release.
