Research Grade 🔥 Most Popular

GLP-3 (Retatrutide)

Also known as Triple GLP agonist

Goal Weight loss

How it works Triple GLP receptor agonist

Storage Keep refrigerated 2–8°C

Formula C₂₂₂H₃₇₃N₆₅O₆₅ · 4811.4 g/mol

You've heard of Ozempic. GLP-3 hits three receptor pathways instead of one — appetite, metabolism, glucagon. Newer research, broader action.

Research Grade Energy

MOTs-c

Also known as Exercise in a vial

Goal Energy & fat loss

How it works Activates AMPK, burns fat at rest

Storage Keep refrigerated 2–8°C

Formula C₁₀₀H₁₉₅N₃₃O₂₂ · 2174.8 g/mol

Your mitochondria make less of this every year after your 30s. The result: cells that are slower to burn fat, less responsive to insulin. MOTs-c tells them to get back to work.

Research Grade Recovery

BPC-157

Also known as Body Protective Compound

Goal Recovery & healing

How it works Promotes tissue repair

Storage Keep refrigerated 2–8°C

Formula C₆₂H₉₈N₁₆O₂₂ · 1419.5 g/mol

Most people arrive here with something that won't heal — a tendon, a joint, a gut that's been off for months. One of the most researched peptides in existence, and the mechanism matches the anecdotes.

SelankComing soon

Research Grade Focus

Selank

Also known as Anxiety off, brain on

Goal Focus & calm

How it works Modulates GABA, boosts BDNF

Storage Keep refrigerated 2–8°C

Formula C₃₃H₅₇N₁₁O₉ · 751.9 g/mol

Anxiety without the fog. Modulates GABA but doesn't sedate you — you just stop feeling like everything is slightly on fire. Useful when you still need to function.

Research Grade Anti-Aging

GHK-Cu

Also known as Copper peptide

Goal Skin, hair & repair

How it works Stimulates collagen & healing

Storage Keep refrigerated 2–8°C

Formula C₁₄H₂₄CuN₆O₄ · 340.4 g/mol

Copper tripeptide your skin used to make more of. Collagen turnover, wound healing speed, hair follicle cycling — all decline as GHK-Cu drops with age. Well-documented across multiple systems.

Research Grade Weight Loss

5-Amino-1MQ

Also known as Fat cell wake-up

Goal Fat loss & metabolism

How it works Blocks NNMT enzyme in fat tissue

Storage Room temp, away from light

Formula C₉H₁₀N₂O · 174.2 g/mol

Some fat stops responding normally — an enzyme called NNMT suppresses metabolism in fat cells and gets worse with time. 5-Amino-1MQ blocks it. Pairs well with GLP compounds.

Research Grade Energy

L-Carnitine

Also known as Fat-to-fuel shuttle

Goal Fat burning & endurance

How it works Moves fatty acids into mitochondria

Storage Keep refrigerated 2–8°C

Formula C₇H₁₅NO₃ · 161.2 g/mol

Moves fatty acids into the mitochondria to be burned. Simple job, does it well. Oral absorption is poor — injectable grade actually shows up at the concentrations that matter.

Research Grade Muscle

CJC-1295 No DAC

Also known as GH pulse amplifier

Goal Muscle growth & recovery

How it works GHRH analogue, boosts GH pulses

Storage Keep refrigerated 2–8°C

Formula C₁₅₂H₂₅₂N₄₄O₄₂ · 3367.9 g/mol

Extends the duration and amplitude of your natural GH pulses rather than replacing them. The no-DAC version has a shorter half-life, which better mimics natural pulsatile release.

Research Grade Weight Loss

Tesamorelin

Also known as Belly fat specialist

Goal Visceral fat reduction

How it works GHRH analogue targeting adipose

Storage Keep refrigerated 2–8°C

Formula C₂₂₁H₃₆₆N₆₈O₇₃S · 5135.9 g/mol

The belly fat whisperer. Targets visceral fat more specifically than most GH releasers — the deep stuff that sits around your organs and ignores cardio. No dramatic hunger spikes, no water retention. Just shows up and does one thing well.

Research Grade Muscle

Ipamorelin

Also known as Clean GH releaser

Goal GH release & sleep

How it works Selective ghrelin receptor agonist

Storage Keep refrigerated 2–8°C

Formula C₃₈H₄₉N₉O₅ · 711.9 g/mol

Triggers GH release without the cortisol spike. Better sleep, cleaner recovery, gradual body composition improvements. Not dramatic, but consistent. Often paired with CJC-1295.

Research Grade Recovery

TB-500

Also known as Whole-body healer

Goal Systemic repair & flexibility

How it works Thymosin β-4 fragment

Storage Keep refrigerated 2–8°C

Formula C₁₂₁H₂₁₆N₃₆O₄₈S · 2888.2 g/mol

Where BPC-157 works locally at the injury site, TB-500 circulates systemically — whole-body tissue repair and anti-inflammatory activity. Different mechanism, same direction. Not a competition.

Research Grade Focus

Semax

Also known as Brain growth hormone

Goal Focus, memory & drive

How it works Upregulates BDNF & dopamine

Storage Keep refrigerated 2–8°C

Formula C₃₇H₅₁N₉O₁₀S · 813.9 g/mol

Boosts BDNF — the protein that builds and maintains neural connections. Sharper focus, better memory, more cognitive drive. Used clinically in Russia for decades.

Research Grade Focus

Pinealon

Also known as Brain longevity peptide

Goal Sleep & neuroprotection

How it works Pineal gland bioregulator

Storage Keep refrigerated 2–8°C

Formula C₁₈H₂₆N₄O₅ · 390.4 g/mol

Tripeptide from the pineal gland. Studied for sleep quality, melatonin regulation, and slowing cognitive decline. Not much noise around it, which probably means it's underrated.

Research Grade Anti-Aging

Epithalon

Also known as Cellular age rewinder

Goal Longevity & anti-aging

How it works Activates telomerase enzyme

Storage Keep refrigerated 2–8°C

Formula C₁₄H₂₂N₄O₉ · 390.4 g/mol

Telomeres shorten every time a cell divides. Epithalon activates telomerase to rebuild them. Decades of research out of the St. Petersburg Institute. Whether that translates to longevity outcomes is still being studied.

HGHComing soon

Research Grade Muscle

HGH

Also known as The master hormone

Goal Muscle, fat loss & recovery

How it works 191 amino acid somatotropin

Storage Keep refrigerated 2–8°C

Formula 191aa somatotropin · 22,124 Da

Lean muscle, fat loss, faster recovery, better sleep. Levels peak around 20 and decline steadily. Everything else in this catalogue either stimulates more of it or fills a gap it doesn't cover.

GlutathioneComing soon

Research Grade Anti-Aging

Glutathione

Also known as Master antioxidant

Goal Detox, skin & immunity

How it works Neutralizes free radicals

Storage Keep refrigerated 2–8°C

Formula C₁₀H₁₇N₃O₆S · 307.3 g/mol

Your body's primary antioxidant. Depleted by stress, illness, alcohol, and ageing. Oral supplementation barely survives the gut — injectable grade actually gets there.

Melanotan 2Coming soon

Research Grade Anti-Aging

Melanotan 2

Also known as Tan & libido activator

Goal Pigmentation & sexual health

How it works Melanocortin receptor agonist

Storage Keep refrigerated 2–8°C

Formula C₅₀H₆₉N₁₅O₉ · 1024.2 g/mol

Activates melanocortin receptors for faster pigmentation and libido. One of the more studied compounds for sexual function in both sexes. Worth reading the side effect profile before you start.

DSIPComing soon

Research Grade Focus

DSIP

Also known as The sleep switch

Goal Deep sleep & stress recovery

How it works Delta wave sleep-inducing peptide

Storage Keep refrigerated 2–8°C

Formula C₃₅H₄₈N₁₀O₁₅ · 848.9 g/mol

Promotes slow-wave sleep, reduces cortisol, normalises disrupted sleep architecture. Sleep is the variable most people are worst at fixing. Everything else works better when this is handled.

KPVComing soon

Research Grade Recovery

KPV

Also known as Inflammation off switch

Goal Gut health & inflammation

How it works Blocks NF-κB inflammatory pathway

Storage Keep refrigerated 2–8°C

Formula C₁₈H₃₅N₅O₆ · 409.5 g/mol

Alpha-MSH fragment with strong anti-inflammatory activity, particularly in the gut lining. Studied for IBD and intestinal inflammation. Often combined with BPC-157 for a more comprehensive approach.

Frequently asked
questions

Peptides are short chains of amino acids that act as signalling molecules in biological systems. Research peptides are synthesised compounds studied for their physiological effects. They are sold for laboratory and investigational use — not as approved medications or supplements.

Yes. All peptides are shipped lyophilised and require reconstitution with bacteriostatic water before use. Use the calculator on this page for exact water volumes and syringe measurements.

We ship Canada-wide via tracked express courier. Most orders ship same business day. Delivery is typically 1–3 business days. All orders are shipped in discreet, unmarked packaging.

Semaglutide (Ozempic) is a GLP-1 agonist — it works on one receptor pathway. GLP-3 is a triple agonist hitting GLP-1, GLP-2, and the glucagon receptor simultaneously. This multi-pathway approach produces significantly greater metabolic effects in research settings.

Lyophilized peptides should be kept refrigerated at 2–8°C and away from light. Once reconstituted, use within 28–60 days depending on compound, and keep refrigerated at all times. Never freeze a reconstituted peptide.

Yes. GLP-3 + MOTs-c + NAD⁺ targets three points in the same metabolic pathway and is a common combination. BPC-157 and TB-500 are frequently combined for connective tissue recovery.

Research peptides are not approved drugs or natural health products under Canadian federal law. They are legal to purchase for laboratory and in vitro research purposes. They are not approved for human or animal use. Purchasing is for qualified research purposes only.

Yes. All orders ship in plain, unmarked packaging with no external reference to Zenith Biolabs or the contents.

We accept crypto only: USDC (on Ethereum) or Bitcoin (BTC). At checkout you'll get our wallet address, an exact amount locked at the live rate, and a QR code. Paste your transaction hash on your order page once you've sent it.

Third-party COAs are in progress. They will be published as they are completed. We do not publish documentation before it has been independently verified.

HPLC purity testing — the standard method across this industry — has inherent measurement variance. A result above 99% is excellent. A result of exactly 100% is not physically possible: analytical methods carry error margins, lyophilisation introduces trace variance, and no real-world compound tests at absolute purity. Any COA reporting 100% is either rounding aggressively or reflects a misunderstanding of the methodology. We will publish our third-party COAs as they are completed and let you read the actual numbers yourself.
