THE FDA DOES NOT APPROVE THIS MESSAGE but we do
a note on how this works

When Eli Lilly — who makes tirzepatide aka Mounjaro and Zepbound — started suing compound pharmacies for making generic versions, we went down the rabbit hole: where are these actually made, how do you source them, how do you ensure safety and quality? We cut out the middleman and went straight to the source.

Along the way we fell in with an online community that values the same things we do. We learned about other peptides (and bioregulators!), too: ones that help you sleep better, repair faster, think more clearly, and hold aging at bay...at least a bit! 🙂 (the FDA does not approve this message)

We source from the top vendors in the peptide world and independently test through a third-party lab. We rarely rely on a manufacturer's testing — and we call it out when we do! — because you should exercise caution with manufacturers' self-reported results (obvi). When we do, it is with consistent suppliers with a solid rep in the business. This community puts safety first, shares results, and looks out for each other. Ordering through us, you're joining that.

A note before you order: These compounds are not FDA-approved for human use. They may or may not be appropriate for you. Do your own research, consult a provider you trust, and never take anyone's word for it — including ours. We share what we know; you make your own decisions.
Blends
GLOW 70
Glow Up
GHK-Cu (50mg) + BPC-157 (10mg) + TB-500 (10mg). Three of the most studied peptides in one vial. As a pre-mixed peptide, this one is typically tested by a human subject before sale rather than a lab. Collagen, repair, regeneration; skin, joints, gut, recovery. A good starting point if you're new to peptides.⚠ GLOW protocol: 6–8 weeks on, same amount of time off. These compounds promote tissue growth and angiogenesis — cycling prevents receptor desensitization and is standard practice in this community. Do not use if you have a history of cancer.
$60
KLOW 80
Glow Plus
Everything in GLOW + KPV (10mg) for deeper gut and immune support. The upgrade for people dealing with inflammation, gut issues, or autoimmune stuff on top of everything else.⚠ Same cycling protocol as GLOW. Do not use if you have a history of cancer.
$70
Metabolic & GLP
Tirzepatide 10mg
The Breaking Good Start
The OG. Originally developed for diabetes, it's a revolutionary drug for weight, inflammation, hormones, addiction, and a growing list of things science is still figuring out. Eli Lilly sells it as Mounjaro and Zepbound.
$35
Tirzepatide 15mg
The Breaking Good
Same compound, higher dose. Most common maintenance dose in research protocols.
$45
Tirzepatide 30mg
The Breaking Good Best
Higher concentration vial. Orange cap. Luther and ABC manufacturers — both tested, both solid.
$60
Retatrutide 10mg
The New Hope
Tirz's overachieving younger sibling. Triple agonist — hits GLP-1, GIP, AND glucagon receptors simultaneously. Even more effective than tirz, though it does come with a couple of pretty minor side effects — do your research. FDA approval likely first half of 2027.
$50
Retatrutide 20mg
The New Hope (stronger)
Higher concentration vial of our triple agonist. Same compound as the 10mg, more vials per reconstitution dollar. For people who are already dialed in on reta and know their dose.
$80
NAD+ 500mg (buffered)
Celeb Fave
NAD+ is involved in every energy-producing process in your body, and levels drop significantly as you age. Studied for cognitive function, DNA repair, metabolic health, and cellular energy. Don't bother taking it orally — the bioavailability sucks. Buffered means it doesn't burn as much going in, but HIGHLY recommend testing pH prior to injecting.⚠ pH test strips included with every NAD+ order (1 per vial). Common protocol: 2–4 weeks on, 2 weeks off. Many people run it at lower frequency (1–2x per week) ongoing.
$38
Recovery & Repair
BPC-157 10mg
Body Workhorse
Gut healing, tendon and ligament repair, systemic anti-inflammatory. Studied for over 30 years. If something hurts, if your gut is a mess, if you're not recovering from workouts the way you used to, check it out.⚠ Should be cycled. Do not use if you have a history of cancer.
$35
TB-500
Best Supporting Peptide
Thymosin Beta-4. BPC-157's bestie and great solo. Tissue regeneration, flexibility, injury recovery. Particularly good for muscle tears, joint issues, and anything where you need tissue to rebuild rather than just reduce inflammation.⚠ Should be cycled. Do not use if you have a history of cancer.
$35
KPV 10mg
Your Gut Buddy
Studied for gut inflammation, IBD, Crohn's, colitis, and systemic immune regulation. If your gut is your weak point, KPV is worth learning more about. Anti-inflammatory at the cellular level. Also being looked at for skin conditions. Part of the KLOW blend.⚠ Common protocol: 4–8 weeks on, 4 weeks off.
$35
Sleep & Stress
DSIP 5mg
Delta Sleep Inducing Peptide
Studied for sleep quality, stress response, and cortisol regulation — not a sedative, more like a signal that tells your brain it's time to wind down. Also looked at for pain modulation and opiate withdrawal support. Works best injected before bed.⚠ Used as needed — typically 3–5x per week before bed rather than daily.
$35
Selank
The Chill Pill
Studied for anxiety reduction, cognitive enhancement, and immune modulation. Described as anxiolytic without sedation — calm without foggy. Popular with people who want anti-anxiety effects without dependency risk. Also being looked at for immune regulation.⚠ Administered intranasally (nasal spray) — not injected. Different delivery than the rest of our catalog; see the reconstitution guide for prep.
$25
PE-22-2
The Mood Lifter
A synthetic peptide fragment studied for antidepressant effects and neurogenesis — it promotes new brain cell growth. Early research is interesting: faster acting than traditional antidepressants and potentially effective for anxiety. Still pretty new to the community but gaining traction fast.
$35
Skin & Collagen
GHK-Cu 50mg
Skin & Hair Beautifier
Your body makes this copper peptide naturally, but makes less of it every decade. Involved in collagen synthesis, skin repair, wound healing, and increasingly interesting neurological research. Works both injected and topically — a lot of people do both.
$35
Longevity
MOTS-C 10mg
Metabolic Powerhouse
Already encoded in your mitochondrial DNA and studied for metabolic regulation, insulin sensitivity, and physical capacity — prompts your muscles to absorb glucose and use body fat for fuel instead. Produced during exercise; levels decline with age.⚠ Common protocol: 5 days on, 2 days off — aligns well with workout schedules.
$35
Epithalon
The Longevity OG
One of the most studied longevity peptides in existence — part of the Khavinson peptide bioregulator family developed in Russia. Studied for telomere elongation, circadian rhythm regulation, and lifespan extension in animal models. If you're interested in aging, this is a foundational one.⚠ Bioregulator note: not independently tested by us, but third-party tested and sourced from a leading manufacturer in the bioregulator space.
$45
Cortagen
The Cardio Peptide
A bioregulator peptide studied for cardiovascular health, specifically for its effects on the heart and blood vessels. Part of the Khavinson peptide bioregulator family — developed in Russia, studied for decades, just now getting mainstream attention in the West.⚠ Bioregulator note: not independently tested by us, but third-party tested and sourced from a leading manufacturer in the bioregulator space.
$45
Ovagen
Gut & Liver Bioregulator
Another Khavinson bioregulator, this one targeting the liver and GI tract. Studied for liver regeneration, gut health, and hepatoprotective effects. Good pairing with BPC-157 for people with serious gut issues.⚠ Bioregulator note: not independently tested by us, but third-party tested and sourced from a leading manufacturer in the bioregulator space.
$45

Good to know

On sourcing: 99% of raw peptide materials originate in China. Quality varies enormously. Independent third-party testing (Janoshik is the standard) is the only way to know what you're actually getting. We test. Never trust a manufacturer's test results.

On cancer history: BPC-157 and TB-500 promote angiogenesis — new blood vessel growth. Great for healing. Contraindicated if you have a history of cancer.

On GLP-1s and muscle: Resistance training and adequate protein are not optional on tirz or reta. Muscle loss is real. Lift heavy, eat protein.

On starting doses: Start low. Always. Your body's response tells you more than any protocol. Titrate slowly. This applies to everything on this site.

On doing your own research: These compounds are not FDA-approved for human use and may not be right for you. Read the studies. Ask questions in the Reddit communities above. Think critically.
