GHRP-2 Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates the pituitary gland to release growth hormone by activating the ghrelin receptor , known as GHS-R1a, the primary growth hormone secretagogue receptor expressed on pituitary cells. It is the only growth hormone secretagogue peptide to have received regulatory approval anywhere in the world , specifically in Japan, where it is used under the name Pralmorelin to diagnose growth hormone deficiency. This guide covers how GHRP-2 works, what the research shows, how it is used and dosed in investigational protocols, its side effect profile including the cortisol and prolactin co-stimulation that distinguishes it from more selective alternatives, and where it stands legally and in sport.

Gonadorelin Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

Gonadorelin is a synthetic decapeptide chemically identical to the body's own gonadotropin-releasing hormone (GnRH), the upstream signal that tells the pituitary gland to release LH and FSH, which in turn drive testosterone production, sperm development, and reproductive function. It is most studied for restoring natural hormone signaling in hypogonadotropic hypogonadism, inducing ovulation in anovulatory females, and testing pituitary function diagnostically. This guide covers what gonadorelin does, how it works through the hypothalamic-pituitary-gonadal axis, what the research shows, dosing context, safety considerations, and its current regulatory status.

FOXO4-DRI Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

FOXO4-DRI is a synthetic senolytic peptide engineered to selectively trigger programmed cell death in senescent cells - the dysfunctional "zombie cells" that accumulate with aging and drive tissue deterioration. It works by disrupting a specific protein-protein interaction between FOXO4 and p53 that senescent cells depend on for survival, freeing p53 to initiate the cell's own death cascade while leaving healthy cells largely unaffected. This guide covers what the FOXO4-DRI peptide does, how it works at a mechanistic level, what preclinical research shows across aging and chemotherapy models, dosing context from published studies, safety considerations, and where the evidence - and its gaps - currently stand.

Follistatin-344 Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

Follistatin-344 (FS-344) is a synthetic analogue of a naturally occurring human protein that neutralizes myostatin and several other members of the TGF-beta superfamily - the signaling proteins that put a biological ceiling on how much muscle your body can build. It is most studied in the context of skeletal muscle growth and preservation, with animal research showing dramatic increases in muscle mass, and early human research focused on gene therapy applications for muscular dystrophy. This guide covers what the Follistatin-344 peptide does, how it works at the molecular level, what the research actually shows, dosing context drawn from preclinical literature, its safety profile, and its current regulatory status.

Epithalon Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

Epithalon is a synthetic tetrapeptide composed of four amino acids in sequence (alanine, glutamic acid, aspartic acid, and glycine), developed from research into pineal gland biology beginning in the 1980s by Professor Vladimir Khavinson's group in Russia. It is primarily studied for its effects on telomere maintenance, melatonin synthesis, immune function in aging, and antioxidant restoration, making it one of the most mechanistically distinctive compounds in the geroprotective peptide research space. This guide covers what the Epithalon peptide is, how it works, what the published research shows, broad dosing context, safety considerations, its current regulatory status, and how it compares to similar compounds.

DSIP Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit cerebral venous blood in 1977 and found in the human brain, gut, adrenal glands, and other tissues. It is studied primarily for its effects on sleep architecture, stress regulation via the HPA axis, and neuroprotection through NMDA receptor modulation and GABAergic activity. This guide covers what DSIP does, how it works, what the human and animal research shows, dosing context from published studies, its safety profile, and its current regulatory status.

CJC-1295 NO DAC Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

CJC-1295 NO DAC is a synthetic 29-amino acid analog of growth hormone-releasing hormone (GHRH), engineered with four strategic amino acid substitutions that improve enzymatic stability while deliberately preserving a short plasma half-life of 30 minutes to 2 hours. Unlike its longer-acting counterpart CJC-1295 WITH DAC, which extends its half-life to 5-8 days via albumin binding, the NO DAC version stimulates pulsatile growth hormone release that mirrors the body's natural secretory rhythms. This guide covers what CJC-1295 NO DAC does, how it works, what the research shows, how it compares to alternatives, dosing context, safety considerations, and its current regulatory status.

CJC-1295 DAC Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research

CJC-1295 DAC is a synthetic, long-acting analog of growth hormone-releasing hormone (GHRH) - the signal your body naturally uses to tell the pituitary gland to release growth hormone. The defining feature of CJC-1295 DAC is its Drug Affinity Complex (DAC) technology, which extends the peptide's active half-life from roughly seven minutes to 5.8-8.1 days by enabling it to bind covalently to circulating albumin in the bloodstream. This guide covers what CJC-1295 DAC does, how the albumin-binding mechanism works, what the human clinical trial data shows, how it compares to CJC-1295 without DAC, dosing context, its safety profile, and its current regulatory status.
