Peptide Library

Every peptide we use,
in plain English.

A clear reference to the peptides and cofactors behind MEDVIVA protocols, what each one is, how it works, and what it's used for. This is educational information, not medical advice. Eligibility and prescribing are always determined by a licensed physician.

Approved medicines vs. research peptides. Read this first. Not everything on this page sits in the same category, and we won't pretend otherwise. The GLP-1 medicines (semaglutide and tirzepatide) are approved by regulators and backed by large human trials. Several other peptides listed here are not approved by any regulator, have no completed human efficacy trials, and are sold as research compounds. They are used only under specialist supervision, where that is legally permitted, on the basis of early or animal-stage evidence. We apply one honest evidence standard to all of them and label each entry below. Whether any given compound is available to you in the UAE depends on its regulatory status and your clinical suitability, decided by a licensed physician.

Group

Metabolic & Fat Loss

GLP-1 and metabolic peptides that regulate appetite, insulin sensitivity and energy use, the basis of ShredStack™.

Semaglutide

GLP-1 agonist
What it is
A GLP-1 receptor agonist originally developed for type 2 diabetes and obesity management.
What it does
Mimics glucagon-like peptide-1 to slow gastric emptying, suppress appetite and improve insulin sensitivity, leading to significant weight loss alongside lifestyle change.
Status
Approved medicine  Approved by regulators for type 2 diabetes and obesity.
Evidence
Strong, established in large randomised controlled trials. Important caveats: it works as ongoing therapy, and weight is commonly regained after stopping; not a one-time cure. Contraindicated with a personal or family history of medullary thyroid cancer or MEN2, and in pregnancy.
Used for
Medical weight lossAppetite controlMetabolic health

Retatrutide

Triple agonist
What it is
A next-generation triple hormone receptor agonist (GLP-1, GIP and glucagon receptors) studied in late-stage trials for obesity and metabolic disorders.
What it does
Studied for appetite suppression, improved insulin sensitivity and increased energy expenditure, with early trial results suggesting larger fat loss than single or dual agonists. These results are from clinical trials and not yet an approved use.
Status
Investigational  In late-stage (Phase III) trials; not yet approved by any regulator, anywhere. It cannot be prescribed as an approved product.
Used for
Advanced weight lossObesity with metabolic syndromeGLP-1 non-responders

MOTS-c

Mitochondrial
What it is
A mitochondrial-derived peptide encoded by the mitochondrial genome.
What it does
Proposed to act on AMPK (the cellular energy sensor) and is studied as an "exercise mimetic" for glucose handling and fat oxidation. To date this is based on animal studies; the effects are not established in humans.
Status
Research use only  Not approved by any regulator. No completed human trials; it is commonly banned in competitive sport (WADA).
Used for
Weight managementInsulin resistanceAthletic performanceMetabolic decline

Group

Recovery & Repair

Regenerative peptides for soft-tissue healing and resilience, the basis of RecoveryStack™ and RepairStack™.

BPC-157

Repair
What it is
A synthetic 15-amino-acid fragment ("Body Protection Compound-157") of a protein found in human gastric juice.
What it does
Studied in animals for angiogenesis (new blood-vessel growth), collagen production and repair of tendon, ligament, muscle and gut tissue, with proposed anti-inflammatory effects. The evidence is preclinical. These benefits are not established in humans.
Status
Research use only  Not approved anywhere. No human trials; currently under FDA compounding review, and relevant in competitive sport (WADA).
Used for
Tendon & ligament injuryMuscle tearsPost-surgical recoveryGut healing

TB-500

Regeneration
What it is
A synthetic version of a segment of thymosin β4, a natural protein present in almost all human and animal cells.
What it does
Proposed to regulate actin (involved in cell structure and movement) and promote cell migration and tissue regeneration. Early evidence is from animal studies only; tissue-repair benefits are not established in humans.
Status
Research use only  Not approved anywhere. No human trials; banned in competitive sport (WADA).
Used for
Orthopedic injuryChronic soft-tissue damagePerformance recoveryWound healing

Group

Aesthetics & Skin

Regenerative peptides for skin, hair and scar improvement.

GHK-Cu

Copper peptide
What it is
A naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) found in human plasma, saliva and urine.
What it does
Prescribed as a compounded subcutaneous injection, the copper-binding tripeptide is studied for stimulating collagen, elastin and glycosaminoglycan synthesis, supporting wound healing and skin and hair quality, with antioxidant effects.
Status
Injectable: clinician-supervised  MEDVIVA dispenses GHK-Cu as a subcutaneous injection compounded by a licensed UAE pharmacy. The strongest published evidence is for topical/cosmetic use; injectable human evidence is still emerging, so it is dosed conservatively for copper load and used only under specialist supervision where permitted.
Used for
Skin rejuvenationHair regrowthWound healingScar & stretch-mark improvement

Group

Hormonal & Growth

Peptides that work with the body's own hormonal systems rather than replacing them, the basis of YouthStack™.

CJC-1295

GHRH analog
What it is
A synthetic analog of growth-hormone-releasing hormone (GHRH) with drug affinity complex (DAC) for an extended half-life.
What it does
Acutely stimulates the pituitary to release growth hormone, raising IGF-1. It is proposed to support recovery, lean mass, fat loss and cellular repair, but a short-term rise in growth hormone is not the same as a proven clinical benefit, which has not been shown in human trials.
Status
Research use only  Not approved anywhere. No human efficacy trials; banned in competitive sport (WADA). The same applies to related growth-hormone-releasing peptides such as ipamorelin.
Used for
Hormonal optimisationMuscle massFat reductionRecovery

Group

Energy & Longevity

Mitochondrial and cellular-ageing support, the basis of MitoStack™ and the longevity side of YouthStack™.

SS-31 (Elamipretide)

Mitochondrial
What it is
A mitochondria-targeted tetrapeptide designed to penetrate cell membranes and bind cardiolipin, a key lipid in the mitochondrial membrane.
What it does
Studied for stabilising mitochondrial membranes (binding cardiolipin), reducing oxidative stress and supporting ATP (energy) production.
Status
Investigational  In legitimate clinical development but not approved for any use. Trials target specific rare mitochondrial diseases. It is not proven for general anti-aging or longevity, and we do not market it that way.
Used for
Mitochondrial dysfunctionChronic fatigueAge-related energy declineNeuro & cardiovascular support

NAD⁺

Coenzyme
What it is
Nicotinamide adenine dinucleotide, a coenzyme essential for cellular energy production, DNA repair and overall vitality, delivered via a dose-adjustable pen (10–100 mg).
What it does
As a coenzyme, it participates in mitochondrial metabolism and DNA-repair pathways. It is proposed to support energy and cellular resilience with age.
Status
Limited evidence  Note that NAD⁺ is a coenzyme, not a peptide. The evidence for IV or injectable NAD⁺ in wellness use is limited and early; benefits are not well established in humans.
Used for
Energy & vitalityCellular repairAnti-ageing protocols

Epithalon

Longevity
What it is
A synthetic peptide version of epithalamin, a natural substance from the pineal gland.
What it does
Proposed to activate telomerase and support telomere maintenance (protective caps on chromosomes), antioxidant defence and hormonal balance. The telomere claim rests on early laboratory work; effects are not established in humans.
Status
Research use only  Not approved anywhere. Human evidence is minimal and very weak (mostly older cell-culture and rodent studies, no human trials).
Used for
Longevity protocolsAge-related preventionImmune rejuvenation

Group

Immune

Immune-modulating peptides used as supportive components in recovery protocols.

Thymosin α-1

Immune modulator
What it is
A 28-amino-acid peptide naturally produced by the thymus gland, available as a purified therapeutic form.
What it does
Modulates the immune system by activating T-cells and supporting dendritic-cell function, studied for resistance to infection and inflammation.
Status
Approved (some countries)  Approved in certain countries for specific immune indications (for example hepatitis B and as an immune adjuvant); status varies by region and it is not a general wellness drug. Availability in the UAE depends on regulatory status and clinical suitability.
Used for
Immune support in chronic illnessViral infectionsImmune recovery after surgery
