Research peptides, held in Australia, out the door the same day.

Retatrutide

What sets retatrutide apart is that one synthetic peptide switches on three receptors together, GLP-1, GIP and glucagon, rather than the single target of semaglutide or the two of tirzepatide. Eli Lilly is still running Phase 3 trials on it, which means no licensed medicine exists yet and the only material available is a research vial of the kind shown here.

It is not available as a medicine anywhere yet, so there is no pharmacy product and no compounded version. Research-grade retatrutide ships from local stock the same business day, as a lyophilised vial or as a ready-to-use pen.

Retatrutide pens

Premixed 3 mL aqueous pens with a 0.5 mg dial in 15mg, 20mg and 30mg, a dual-chamber cartridge pen that mixes lyophilised retatrutide with sterile water at activation in 70mg, and other strengths filled to order, all shipped cold from Australian stock. The pen suits research designs that need repeatable handling; the vials suit work that needs a chosen concentration.

Kits

A vial or pen with the bacteriostatic water, syringes or pen needles and swabs it needs, in one box. Starter kits for a first retatrutide vial or pen, pairs for CJC-1295 + Ipamorelin, Semax + Selank and BPC-157 + TB-500, and stacks for GLOW and KLOW.

BPC-157

A stable sequence of 15 amino acids lifted from a protective protein in human gastric juice, BPC-157 ranks among the most heavily cited repair peptides in the preclinical record. Several hundred rodent experiments have examined it across tendon, ligament, muscle, gut and nervous-system injury. Part of what sets it apart is its durability: it withstands stomach acid and stays active in solution for days.

The 10mg vial for tissue-repair models, 500 mcg capsules for oral and gut research, and the BPC-157 + TB-500 blend. Our guides explain which format the evidence used and where BPC-157 stands with the TGA.

GHK-Cu

GHK-Cu is a tripeptide that occurs in nature and binds copper with high affinity. First isolated from human plasma in 1973, its concentration drops from around 200 ng/mL in young adults to roughly 80 ng/mL by age 60. Researchers study it across wound repair, collagen synthesis, hair follicle biology and gene-expression changes in aged tissue. The same molecule turns up at low levels in cosmetic serums; the research vial holds the pure copper complex.

Two vial sizes of the copper complex, plus the GLOW blend that pairs it with BPC-157 and TB-500.

Tesamorelin

Tesamorelin is a 44-amino-acid GHRH analogue carrying a trans-3-hexenoic acid group on its N-terminus that shields it from enzymatic breakdown. Its reputation comes from the HIV-associated lipodystrophy trials, in which it cut visceral abdominal fat while avoiding the wider metabolic effects that recombinant growth hormone tends to produce.

Not registered in Australia, so not in pharmacies; stocked here as a research vial in three sizes.
