Peak Wolverine injection pen

BPC-157 · TB-500 · GHK-Cu

Peak Wolverine

Heals faster. Moves better.

  • Targets tendons & ligaments — tissues with poor natural blood supply
  • BPC-157 promotes angiogenesis and modulates nitric-oxide repair pathways
  • TB-500 (Thymosin β4) speeds cell migration into damaged tissue
New
Peak Pulse injection pen

MOTS-C

Peak Pulse

Endurance, metabolism & performance.

  • Activates AMPK — the cell's master energy sensor
  • A mitochondrial-derived peptide the body releases during exercise (an "exercise mimetic")
  • Supports glucose regulation and insulin sensitivity
Peak Libido injection pen

HCG

Peak Libido

Hormones, libido, mood.

  • Supports the body's natural testosterone production pathways
  • Acts like luteinising hormone (LH) on the testes — preserves function
  • Studied for improvements in libido, mood and energy
New
Peak Rewind injection pen

NAD+

Peak Rewind

The molecule your cells run on.

  • Fuels mitochondrial ATP production — cellular energy
  • Obligatory cofactor for sirtuins (the longevity enzymes)
  • Substrate for PARP-driven DNA repair
New
Peak Glow injection pen

GHK-Cu · Ipamorelin · CJC-1295 · Epithalon

Peak Glow

Boosts collagen & smooths fine lines.

  • GHK-Cu activates fibroblasts — the cells that build collagen
  • Ipamorelin + CJC-1295 lift growth hormone & IGF-1 for skin renewal
  • Epithalon supports telomerase & antioxidant defence at the cellular level
New
Peak Youth injection pen

CJC-1295 DAC

Peak Youth

Growth-hormone support & vitality.

  • A long-acting GHRH analogue — signals sustained growth-hormone release
  • The DAC form extends action for days from a single dose
  • Raises downstream IGF-1 for recovery and tissue maintenance
New
Peak Sun injection pen

Melanotan II

Peak Sun

Tan with less sun.

  • Stimulates melanocytes to produce melanin via the MC1R receptor
  • Shifts pigment toward eumelanin — the brown-black, longer-lasting tan
  • Studies show ~50% less UV needed for equivalent tanning

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.

Build Your Stack.

Most customers run 2–3 formulas simultaneously. Wolverine + Burn + Rewind is the most popular combination.

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.
