Muscle & Growth
Gonadorelin Acetate
ClinicalPreserve natural testosterone via HPG axis activation
Gonadorelin Acetate is a synthetic decapeptide identical to endogenous gonadotropin-releasing hormone (GnRH), produced and secreted by the hypothalamus. It stimulates the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thereby supporting endogenous testosterone and estrogen production. It is used clinically to assess pituitary function, treat hypogonadism, support fertility, and is increasingly used alongside anabolic protocols to preserve testicular function.

Human Chorionic Gonadotropin (HCG)
ClinicalThe LH Mimic for Hormonal Restoration
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone naturally produced by the placenta during pregnancy, structurally similar to luteinizing hormone (LH). In clinical and research settings, it is used to stimulate testosterone production in men, support fertility, and maintain testicular function during or after anabolic steroid use. It acts directly on the gonads to mimic LH signaling, making it a cornerstone of hormonal restoration protocols.

Human Growth Hormone (HGH)
ClinicalThe master anabolic and lipolytic growth hormone
Human Growth Hormone (HGH) is a 191-amino acid peptide hormone naturally secreted by the anterior pituitary gland that regulates growth, body composition, and metabolism. In clinical and performance contexts, recombinant HGH (rhGH) is administered exogenously to mimic or augment endogenous GH signaling. It is one of the most studied anabolic and lipolytic compounds in endocrinology, with established uses in GH deficiency, muscle-wasting conditions, and anti-aging protocols.

Human Menopausal Gonadotropin (HMG)
ClinicalDual gonadotropin for fertility and testicular function
Human Menopausal Gonadotropin (HMG) is a purified preparation of gonadotropins extracted from the urine of postmenopausal women, containing both Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) activity in approximately equal ratios. In clinical medicine it is used to stimulate ovulation in women and spermatogenesis in men, particularly those with hypogonadotropic hypogonadism. In performance and fertility contexts, HMG is used alongside or after hCG to restore or maintain testicular function, intratesticular testosterone production, and sperm output.

Triptorelin Acetate
ClinicalGnRH analogue for hormonal axis modulation
Triptorelin Acetate is a synthetic decapeptide analogue of gonadotropin-releasing hormone (GnRH) used clinically to treat hormone-sensitive conditions such as prostate cancer, endometriosis, and central precocious puberty. Upon initial administration it causes a transient surge in luteinizing hormone (LH) and follicle-stimulating hormone (FSH), followed by sustained suppression of gonadal steroid production through pituitary receptor desensitization. In research and off-label contexts, single low-dose administration has been explored as a means to transiently restore hypothalamic-pituitary-gonadal (HPG) axis function in individuals with post-anabolic-steroid-induced hypogonadism.

Human-limitedSynergistic GH pulse amplifier for body and recovery
CJC-1295 (without DAC) + Ipamorelin is a synergistic peptide blend combining a growth hormone-releasing hormone (GHRH) analogue with a selective growth hormone secretagogue. Together, they stimulate the pituitary gland to release growth hormone in a pulsatile, physiologically natural manner. This combination is widely used for body composition improvement, recovery, anti-aging, and sleep quality enhancement.

CJC-1295 (Without DAC)
Human-limitedNatural GH Pulses for Growth and Recovery
CJC-1295 without DAC (also known as Modified GRF 1-29) is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to release growth hormone in a pulsatile, physiologically natural pattern. It consists of the first 29 amino acids of GHRH with four key amino acid substitutions that enhance stability and receptor affinity compared to the native peptide. It is widely used in research settings for its potential to promote lean muscle growth, fat loss, recovery, and anti-aging effects.

CJC-1295 with DAC
Human-limitedLong-acting GHRH analog for sustained GH release
CJC-1295 with DAC is a synthetic, long-acting analog of growth hormone-releasing hormone (GHRH) that incorporates a Drug Affinity Complex (DAC) to dramatically extend its half-life. By binding covalently to serum albumin, it maintains sustained elevation of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) for up to two weeks per injection. It is used in research settings to study GH secretion, body composition changes, and recovery processes.

Hexarelin Acetate
Human-limitedPotent GH secretagogue with cardiac benefits
Hexarelin Acetate is a synthetic hexapeptide and potent growth hormone secretagogue (GHS) that stimulates pituitary release of growth hormone (GH) by mimicking the action of ghrelin. It binds to the GHS-R1a receptor with high affinity and also exhibits direct cardioprotective effects independent of GH release. Developed originally as a potential treatment for GH deficiency, it is one of the most potent GH-releasing peptides studied in clinical research.

HGH Fragment 176-191
Human-limitedTargeted fat-loss fragment of growth hormone
HGH Fragment 176-191 is a synthetic peptide derived from amino acids 176–191 of the C-terminus of human growth hormone (hGH). It was specifically engineered to retain the lipolytic (fat-burning) properties of hGH while eliminating its growth-promoting and insulin-desensitizing effects. Research, primarily in animal models, suggests it stimulates fat breakdown and inhibits the formation of new fat cells.

FST 344
AnimalMyostatin blocker for serious muscle hypertrophy
FST 344 is a recombinant isoform of follistatin, a naturally occurring glycoprotein that binds and neutralizes myostatin and activin, two potent inhibitors of muscle growth. By suppressing these negative regulators, FST 344 promotes skeletal muscle hypertrophy, enhances recovery, and may support bone density. It has been investigated in gene therapy and preclinical contexts for muscular dystrophy and sarcopenia, though human clinical data remain very limited.

GDF-8 (Myostatin)
AnimalThe Master Brake on Muscle Growth
GDF-8, also known as myostatin, is a TGF-β superfamily member that acts as a potent negative regulator of skeletal muscle mass. It limits muscle fiber size and number by inhibiting myoblast proliferation and differentiation. Research into myostatin inhibition has generated significant interest for applications in muscle wasting diseases, metabolic disorders, and athletic performance.

GHRP-3 is a synthetic hexapeptide and member of the growth hormone releasing peptide family, designed to stimulate the pulsatile release of growth hormone (GH) from the anterior pituitary gland. It acts primarily as a ghrelin mimetic and GHS-R1a agonist, amplifying natural GH secretion pulses. GHRP-3 is structurally related to GHRP-2 and GHRP-6 but exhibits a modified amino acid sequence intended to reduce appetite-stimulating side effects while maintaining GH secretagogue potency.

Mechano Growth Factor (MGF) is a splice variant of Insulin-like Growth Factor 1 (IGF-1) that is produced locally in muscle and other tissues in response to mechanical stress or damage. It plays a critical role in activating satellite cells (muscle stem cells) to initiate repair and hypertrophy. MGF is primarily of interest to researchers studying muscle regeneration, athletic recovery, and tissue repair.

AnecdotalPituitary GH secretagogue for growth and recovery
GHRP-4 is a synthetic hexapeptide ghrelin mimetic designed to stimulate the pituitary gland's release of endogenous growth hormone. It belongs to the same family as GHRP-2 and GHRP-6 but is a less extensively characterized analog with a modified structure aimed at optimizing GH release with a potentially reduced appetite-stimulating side effect profile. Research on GHRP-4 specifically is limited compared to its better-studied relatives, and most mechanistic understanding is extrapolated from the broader GHRP class.
