Tells your body to burn fat, stop storing it, and feel full — all at once. The most powerful fat loss compound in research.
Retatrutide is a triple receptor agonist — meaning it activates three separate hormonal pathways at the same time. Most weight loss drugs only target one. GLP-1 suppresses appetite and slows digestion so you feel full longer. GIP regulates how your body stores fat — essentially telling fat cells to stop hoarding energy. Glucagon increases how much energy your body burns at rest, even when you're not moving.
Hitting all three simultaneously creates a compounding effect that no single-target compound can match. Phase III clinical trials reported up to 30% body weight reduction — the highest ever recorded in a peptide research compound. It's administered once weekly via subcutaneous injection, making it one of the most convenient protocols available.
What makes Retatrutide particularly significant in the research context is its selectivity. It doesn't simply suppress appetite — it changes the metabolic environment at a hormonal level, affecting how the body allocates and stores energy. Researchers studying body composition, metabolic syndrome, and obesity have shown strong interest in this compound precisely because of this multi-pathway mechanism.
Two repair compounds in one vial. One fixes the injury site, the other sends your body's healing system into overdrive.
BPC-157 stands for Body Protection Compound 157 — a peptide originally derived from a protein found in stomach acid. Research shows it accelerates repair of tendons, ligaments, muscle, and gut lining by stimulating new blood vessel growth directly at the injury site. It also has a strong effect on the gut-brain axis, with studies showing benefits for inflammation and digestive health.
TB-500 is a synthetic version of Thymosin Beta-4, a protein naturally present in almost every cell in the body. It works systemically — meaning it travels through the bloodstream rather than staying local. It mobilises stem cells, promotes tissue regeneration, reduces inflammation, and has been studied for cardiac repair and flexibility improvements.
Together, the two compounds cover both local and systemic healing simultaneously — which is why this blend has become the go-to recovery stack in peptide research. BPC-157 acts at the site of damage while TB-500 coordinates the body's broader repair response. The combination produces a synergistic effect that neither compound achieves alone.
A signal your mitochondria produce naturally — but less of as you age. Turns your cells back into efficient fat-burning machines.
MOTS-c is one of the most unusual peptides in existence — it's encoded not in your nuclear DNA like most proteins, but in your mitochondrial DNA. Mitochondria are the energy-producing organelles inside every cell, and MOTS-c is essentially a signal they produce to regulate how the whole body uses fuel.
It activates AMPK, an enzyme often called the master metabolic switch. When AMPK is activated, your body prioritises burning fat over storing it, improves insulin sensitivity so glucose is used more efficiently, and shifts energy production into a more optimised state. Research also suggests MOTS-c plays a role in longevity pathways, with studies in animal models showing extended lifespan.
The problem is that natural MOTS-c levels decline significantly with age — which is exactly when metabolic function tends to deteriorate. This decline correlates with increased fat storage, reduced insulin sensitivity, and declining mitochondrial efficiency. Researchers studying metabolic aging and type 2 diabetes prevention have focused heavily on this compound as a result.
Tells your body to make more of its own growth hormone — not inject it. Targets belly fat specifically.
Tesamorelin works by mimicking GHRH — Growth Hormone Releasing Hormone — the signal your hypothalamus normally sends to the pituitary gland to trigger natural GH production. This is a fundamentally different approach from injecting synthetic HGH directly. Because your own pituitary gland produces the growth hormone, the release follows your body's natural pulsatile rhythm, which is considered significantly safer and more physiologically appropriate than exogenous HGH.
It has FDA approval for the treatment of HIV-associated lipodystrophy — a condition involving excess visceral fat — which gives it one of the strongest clinical evidence bases of any peptide in this category. Clinical trials showed 15–20% reduction in visceral adipose tissue, the deep fat stored around your organs that's directly linked to metabolic disease.
Users also report improved sleep quality, sharper cognition, and better body composition over time. The mechanism is particularly well understood — it doesn't suppress your body's natural GH axis, which means it's considered more sustainable for long-term research protocols than direct HGH administration. Administered daily via subcutaneous injection, ideally before bed when natural GH pulses are highest.
A copper peptide your body already makes — just less of it over time. Rebuilds skin, tissue, and fights inflammation.
GHK-Cu is a naturally occurring copper peptide complex that your body produces on its own — but levels drop sharply after your 20s. At 20 years old, plasma levels are around 200 ng/mL. By 60, they've fallen to around 80 ng/mL. This decline correlates directly with a slowdown in the body's ability to repair and regenerate tissue.
GHK-Cu works by binding to copper ions and activating a cascade of regenerative processes: it upregulates collagen and elastin synthesis, promotes wound healing, stimulates hair follicle growth, and modulates inflammation. It also activates genes associated with tissue remodeling and downregulates genes linked to inflammation and cancer progression — making it one of the most broadly studied peptides in longevity research.
Unlike many compounds, GHK-Cu has a long track record in published literature, with research dating back to the 1970s. It can be used topically or via subcutaneous injection depending on the research application. The 50mg vial size offers exceptional value for extended research protocols given the relatively low per-dose cost.
Targets your mitochondria directly — the power plants inside every cell. Reduces cellular stress and protects the heart.
SS-31 (also known as Elamipretide) is unlike most antioxidants in one critical way: it actually gets inside the mitochondria. Most antioxidants — even powerful ones — work outside the cell or in the cytoplasm. SS-31 is specifically engineered to penetrate the mitochondrial membrane and concentrate at the inner membrane, where the majority of oxidative stress and free radical damage occurs.
Once there, it stabilises cardiolipin — a phospholipid that's essential for mitochondrial function and energy production. When cardiolipin is damaged by oxidative stress, mitochondrial efficiency collapses, ATP production drops, and cells begin to dysfunction. SS-31 protects and restores cardiolipin integrity, which has downstream effects on cellular energy output, inflammation, and organ health.
It has been studied extensively for heart failure, kidney disease, age-related muscle loss, and neurodegenerative conditions. In several animal models, SS-31 reversed age-related mitochondrial decline — one of the most promising findings in longevity peptide research. For researchers focused on cardiovascular health or cellular aging, SS-31 represents one of the most mechanistically targeted compounds available.
