Which Peptide Protocol Fits Your Goals?
Evidence-based education on the most commonly prescribed peptide therapies. Not medical advice — always consult a licensed provider.
GLP-1 Agonists
Semaglutide, Tirzepatide
Mimics the GLP-1 hormone to regulate appetite, slow gastric emptying, and improve insulin sensitivity. Gold standard for sustainable weight loss.
Sermorelin
GRF 1-29
A growth hormone-releasing hormone (GHRH) analog that stimulates the pituitary to produce natural growth hormone. Supports muscle growth, fat loss, and recovery.
BPC-157
Body Protection Compound-157
A pentadecapeptide derived from human gastric juice. Shown to promote angiogenesis, accelerate wound healing, and reduce inflammation in preclinical studies.
CJC-1295
GRF 1-29 + DAC
Growth hormone-releasing factor with a drug affinity complex (DAC) that extends half-life. Increases IGF-1 levels and supports lean body composition.
Ipamorelin
N,N-dimethyl-GHRP-2
A selective growth hormone secretagogue (GHS) that stimulates GH release with minimal cortisol side effects. Known for clean, targeted action.
PT-141
Bremelanotide
A melanocortin peptide that activates MC3-R and MC4-R receptors, enhancing arousal and sexual function through a non-vascular mechanism.
Thymosin Alpha-1
Tα1
An immune-modulating peptide that enhances T-cell function, reduces inflammation, and supports viral clearance. Used off-label for immune optimization.
TB-500 (Thymosin Beta-4)
Thymosin Beta-4, Tβ4
A naturally occurring peptide involved in tissue repair and regeneration. Promotes cell migration, blood vessel formation, and reduces inflammation systemically.
AOD-9604
Anti-Obesity Drug 9604
A modified fragment (amino acids 177-191) of human growth hormone targeting fat metabolism. Stimulates lipolysis without the growth or blood sugar effects of full HGH.
GHK-Cu (Copper Peptide)
Glycyl-L-histidyl-L-lysine copper
A naturally occurring copper-binding peptide that declines with age. Stimulates collagen synthesis, promotes wound healing, and has been shown to reverse gene expression to a more youthful state.
Epitalon
Epithalon, Epithalamin
A synthetic tetrapeptide that activates telomerase, the enzyme responsible for maintaining telomere length. Studied for anti-aging and circadian rhythm regulation via melatonin pathways.
MOTS-C
Mitochondrial ORF of the 12S rRNA type-C
A mitochondrial-derived peptide that regulates metabolic homeostasis. Acts as an exercise mimetic, improving insulin sensitivity and fat metabolism at the cellular level.
KPV
Lysine-Proline-Valine
An anti-inflammatory tripeptide derived from alpha-MSH. Reduces intestinal inflammation and has shown promise for inflammatory bowel conditions and gut health.
Semax
MEHFPGP
A synthetic peptide analog of ACTH(4-10) that boosts BDNF production. Approved in Russia for cognitive enhancement and stroke recovery. Enhances focus, memory, and neuroprotection.
Selank
TP-7
A synthetic peptide analog of tuftsin that modulates GABA and serotonin pathways. Provides anxiolytic effects without sedation or dependency. Approved in Russia for anxiety and cognitive function.
Melanotan II
MT-2, MT-II
A synthetic melanocortin peptide that stimulates melanin production. Originally developed for skin cancer prevention through UV-free tanning, but carries notable side effects.
LL-37 (Cathelicidin)
Cathelicidin LL-37
A human antimicrobial peptide that plays a key role in innate immunity. Provides direct antimicrobial defense and modulates immune cell signaling.
DSIP (Delta Sleep-Inducing Peptide)
Emideltide, DSIP
A neuropeptide that promotes delta-wave deep sleep. Discovered in 1977, it has been studied for insomnia, stress, and pain management. Works through multiple sleep-regulating pathways.
PEG-MGF
PEGylated Mechano Growth Factor
A PEGylated form of mechano growth factor (a splice variant of IGF-1) that promotes localized muscle repair and hypertrophy. The PEG modification extends its half-life.
Kisspeptin-10
Kisspeptin, KP-10
A neuropeptide that plays a central role in the hypothalamic-pituitary-gonadal axis, regulating GnRH release. Being studied for hormone regulation and reproductive health.
