Semaglutide
A GLP-1 receptor agonist that mimics the gut hormone glucagon-like peptide-1. It slows gastric emptying, signals fullness to the brain, and improves insulin sensitivity for sustained weight loss.
Tirzepatide
A first-in-class dual GLP-1 and GIP receptor agonist. By activating two incretin pathways it delivers greater appetite suppression and fat loss than single-pathway agents.
Retatrutide
A next-generation triple agonist of GLP-1, GIP, and glucagon receptors. The added glucagon signaling increases energy expenditure and hepatic fat mobilization.
Cagrilintide
A long-acting amylin analogue that promotes deep satiety. Often combined with semaglutide (CagriSema) for synergistic appetite control and weight loss.
MOTS-C
A mitochondrial-derived peptide that improves insulin sensitivity and metabolic homeostasis by regulating energy production at the cellular level.
5-Amino-1MQ
A small molecule that inhibits NNMT, an enzyme linked to fat accumulation. This raises intracellular NAD+ and shifts cells toward fat oxidation.
AOD-9604
A modified fragment of human growth hormone (amino acids 177–191) that stimulates lipolysis (fat breakdown) and inhibits lipogenesis — without affecting blood sugar or growth.
Lipo-B (MIC+B12)
A lipotropic blend combining Methionine, Inositol, Choline (MIC) and B-vitamins to help the liver metabolize fat and convert it into usable energy.
SANA (MVD1)
An emerging mitochondrial-support peptide designed to optimize energy production, reduce oxidative stress, and promote cellular repair at the mitochondrial level.
Glutathione
The body's master antioxidant, composed of three amino acids. It neutralizes free radicals, supports detoxification, and recycles other antioxidants.
NAD+
A vital coenzyme found in every cell that powers mitochondrial energy production and activates sirtuins — proteins that govern DNA repair and aging.
SS-31 (Elamipretide)
A mitochondria-targeted peptide that binds cardiolipin in the inner mitochondrial membrane, restoring energy production and reducing cellular stress.
FOXO4-DRI
A senolytic peptide that disrupts the interaction between FOXO4 and p53, selectively forcing senescent ('zombie') cells to self-clear so healthy tissue can regenerate.
BPC-157 & TB-500
A synergistic blend: BPC-157 (a gastric-derived peptide) accelerates angiogenesis and gut healing, while TB-500 (Thymosin Beta-4) promotes cell migration and tissue remodeling.
ARA-290
A synthetic 11-amino-acid peptide derived from erythropoietin that reduces inflammation and supports nerve repair — without stimulating red blood cell production.
Cartalax
A peptide bioregulator designed to target cartilage tissue, supporting the repair and maintenance of joint cartilage and connective structures.
GHK-Cu (Copper Peptide)
A naturally occurring copper-binding peptide that stimulates collagen and elastin production, promotes tissue remodeling, and supports skin and hair regeneration.
KPV
A tripeptide derived from alpha-MSH with potent anti-inflammatory properties. It helps calm gut inflammation, skin conditions, and systemic inflammation.
Sermorelin
A growth hormone-releasing hormone (GHRH) analog that stimulates your pituitary to produce its own natural growth hormone, preserving the body's natural feedback loop.
Tesamorelin
A stabilized GHRH analog (FDA-approved for HIV-associated lipodystrophy) that potently stimulates endogenous growth hormone, targeting visceral fat.
CJC-1295 + Ipamorelin
A synergistic blend: CJC-1295 (a GHRH analog) extends the GH pulse while Ipamorelin (a GHRP) amplifies it — without spiking cortisol, prolactin, or appetite.
IGF-1 LR3
A long-acting analog of insulin-like growth factor 1 that mediates many of growth hormone's muscle-building and recovery effects, with an extended half-life.
LL-37
A cathelicidin-family antimicrobial peptide that directly neutralizes bacteria, viruses, and fungi while modulating the immune response and promoting wound healing.
Thymosin Alpha-1
A thymic peptide that enhances T-cell maturation and immune signaling, helping the body mount a balanced, effective immune response.
Semax
An ACTH-derived neuropeptide that increases brain-derived neurotrophic factor (BDNF) and supports dopamine and serotonin signaling for focus and mental stamina.
Selank
An anxiolytic neuropeptide related to Semax that calms the nervous system and balances neurotransmitters without sedation or dependency.
Dihexa
An angiotensin-IV analog developed to potently stimulate synapse formation and neurogenesis — considered one of the strongest cognitive-enhancing peptides.
PT-141 (Bremelanotide)
A melanocortin receptor agonist that works through the nervous system (rather than blood flow) to enhance sexual arousal and desire in both men and women.
Kisspeptin
A neuropeptide that stimulates GnRH release, upstream of the body's reproductive hormone cascade — supporting healthy libido and hormonal signaling.
Oxytocin
The 'bonding hormone' neuropeptide that promotes social connection, trust, intimacy, and sexual function while calming the stress response.
DSIP (Delta Sleep-Inducing Peptide)
A neuropeptide that promotes deep, restorative slow-wave sleep and helps regulate the body's stress response and circadian rhythm.
Epithalon (Epitalon)
A pineal-gland peptide bioregulator that activates telomerase to help maintain telomere length — a key marker of cellular aging and longevity.
Pinealon
A peptide bioregulator targeting the pineal gland to support melatonin production, sleep regulation, and cognitive longevity.
VIP (Vasoactive Intestinal Peptide)
A widely acting neuropeptide that supports circadian rhythm, immune balance, vascular tone, and gut health — often depleted in chronic stress.
Glow Blend
A Signal Wellness signature aesthetic blend built around skin-rejuvenating peptides (including GHK-Cu) to stimulate collagen, elasticity, and a radiant complexion from within.
Klow Blend
A Signal Wellness signature blend formulated to calm the nervous system and support restful sleep and recovery. Ask our team whether it fits your protocol.
