Mechanisms

The Science Behind It.

Single compounds, pharmaceutical-grade purity, clinical doses. Not proprietary blends — every ingredient named, every dose disclosed.

BPC-157 — Wolverine

A 15-amino-acid peptide naturally present in human gastric juice. Upregulates growth hormone receptors in tendon fibroblasts, promotes angiogenesis (new blood vessel formation), and accelerates repair of tendons, ligaments, and muscle. Studied at 2–10 mcg/kg in multiple animal RCTs. Peak delivers at the upper clinical-study dosing range.

Retatrutide — Burn

A triple-receptor agonist targeting GLP-1, GIP, and glucagon pathways simultaneously. Phase II trials published in NEJM (2023) showed up to 24.2% body weight reduction over 48 weeks at 12mg — more than any prior compound in its class. Hunger signals are suppressed at the hypothalamic level. This is not willpower. It is biology.

MOTS-C — Pulse

A mitochondria-derived signalling peptide that activates AMPK, the cellular energy sensor. Enhances metabolic flexibility — the ability to switch fuel sources efficiently. Research at Johns Hopkins (2015, Lee et al.) demonstrated improved insulin sensitivity and skeletal muscle energy production in animal models. The compound your mitochondria make less of as you age.

Torn labrum, 6 months of physio doing nothing. Three weeks on Wolverine and I was back pressing. Six weeks and I was back to full load. I’d tried four other peptide sources before Peak — none of them came close.
Michael R. — Gold Coast, 36, competitive CrossFitter — Wolverine (BPC-157 + TB-500)
★★★★★
Down 11.4kg in 8 weeks on Burn. I’ve been on Ozempic before — the hunger suppression on Retatrutide is categorically different. No side effects. Just… food stopped being an obsession.
James T. — Sydney, 42, runs his own business — Burn (Retatrutide)
★★★★★
My dermatologist asked what I’d changed. Eight weeks on Glow. I told her. She wrote it down.
Sarah L. — Melbourne, 44, architect — Glow (GHK-Cu + Ipamorelin)
★★★★★
I was sceptical. I’ve spent too much on supplements that do nothing. Rewind is different — cognitive clarity in week two, energy by week three. It’s not placebo. I know what placebo feels like.
Emma K. — Brisbane, 51, GP — Rewind (NAD+)
★★★★★
Achilles rupture. Surgeons said 9-12 months return to play. I was back on the paddock in 19 weeks. I can’t prove the Wolverine did it but I’d be an idiot not to run it again.
David W. — Perth, 29, AFL footballer — Wolverine (BPC-157 + TB-500 + GHK-Cu)

FAQ

Common Questions.

Yes. Peptides for research and educational purposes are legally purchasable by Australian adults. They are not scheduled for retail prohibition under the TGA's current framework when sold with appropriate disclaimers. All Peak formulas are compounded in Australian facilities.
WADA-prohibited peptides include GH secretagogues (Ipamorelin, CJC-1295) and certain other compounds. If you compete under anti-doping testing, review the WADA prohibited list specific to your sport before ordering. BPC-157, NAD+, and MOTS-C are not currently on the WADA prohibited list as of 2026 — but regulations change. When in doubt, check with your sport’s governing body before use.
Three differences. First, ours is compounded in Australia under Australian manufacturing standards — imported peptides have no enforceable purity requirement and frequently test below label claim at independent labs. Second, our formulas are pre-blended in clinical ratios (e.g. Wolverine’s BPC-157 + TB-500 combination is based on the dual-protocol used in most positive outcome research). Third, you’re not waiting 4-6 weeks for a parcel from a grey-market source — we ship express, AU-wide.
We offer a 30-day full refund, no questions, no return postage required. We expect you to notice something within 30 days — if you don’t, we’ll return the $299 in full. That is not a marketing line. It reflects our confidence in the quality of what we compound.
Start with one formula tied to your primary goal: injury/repair → Wolverine. Fat loss → Burn. Cellular longevity → Rewind. Skin/collagen → Glow. Most customers who re-order within 60 days stack 2–3 formulas (Wolverine + Burn + Rewind is the most common combination). The Stack Builder section above shows typical pairings.
