Frequently Asked Questions

Orders placed and paid before 3pm on a business day are sent out the same day. Later orders go out the next business day.

Every order ships by standard or express post, whichever you choose at checkout. Lyophilized peptides are stable in transit, and you should refrigerate the vials when the parcel arrives.

We accept PayID and bank transfer. After you place an order, we show the payment details and your order number to use as the reference. PayID payments usually arrive within minutes; bank transfers can take 1 to 2 business days to clear. We dispatch once payment is received.

Standard is $12. Express is $29. The cost is shown at checkout before you pay.

We email a tracking number when your order is dispatched. You can also check the order tracking page with your order number and email.

We cannot accept change-of-mind returns on temperature-sensitive research products once dispatched. If an item is wrong, damaged or lost, contact us within 7 days and we will replace or refund it.

Enter the lot number printed on the vial label into the COA lookup page. If it is not listed, email us with the product and lot number and we will send it.

You can buy research peptides online from Chainwell Peptide, an Australian supplier that packs and dispatches every order from within Australia. The range covers metabolic, tissue repair, growth hormone, melanocortin, mitochondrial, nootropic, skin, immune and longevity peptides, plus bacteriostatic water, syringes and kits.

Yes. Every lot is tested by an independent laboratory before release: mass spectrometry confirms identity and HPLC measures purity. Each vial carries a lot number that matches its certificate of analysis, which you can check on our COA lookup page before you order.

Orders paid before 3pm on a business day are dispatched the same day by tracked standard or express post. Standard post usually arrives in 3 business days and express in 1 business day after dispatch; regional and remote addresses can take longer.

We accept PayID and bank transfer. PayID payments usually arrive within minutes, while bank transfers can take one to two business days to clear. Use your order number as the payment reference so we can match it and dispatch quickly.

Bacteriostatic water is sterile water with 0.9% benzyl alcohol, used to dissolve lyophilized peptide powder. The benzyl alcohol inhibits bacterial growth, so a single vial can be punctured several times over about 28 days.

Research use only means the products are sold for laboratory and in vitro research. They are not approved drugs, supplements or cosmetics, and they are not for human or veterinary use. By placing an order, buyers confirm they will use products for research.

Retatrutide activates three receptors: GIP, GLP-1 and glucagon. Tirzepatide activates two: GIP and GLP-1. The added glucagon receptor activity is the main reason studies choose retatrutide, while tirzepatide is often used as the dual agonist comparator. Both are supplied here as lyophilized powder.

Order the size you will use within about 28 days of reconstitution, since that is the usual limit for a mixed multi-dose vial kept at 2 to 8 °C. Smaller studies usually start with 10 mg. Larger ongoing protocols save per milligram with the 20 mg or 30 mg vial.

Neither is better in general; they are studied for different mechanisms. BPC-157 is a gastric-derived pentadecapeptide, while TB-500 is a thymosin beta-4 fragment. If the study compares them, buy separate vials. If the protocol calls for both together at a set ratio, the blend saves a reconstitution step.

The copper ion in GHK-Cu gives the powder and the solution a blue colour, which is normal and expected. A GHK-Cu vial with a white cake would suggest the copper complex is missing, so check the lot number against its certificate of analysis.

CJC-1295 without DAC is Modified GRF (1-29), a GHRH analogue with four amino acid substitutions and no drug affinity complex. Its half-life is about 30 minutes, compared with roughly 6 to 8 days for the DAC version. It is the form usually paired with ipamorelin.

Many labs dissolve IGF-1 LR3 in 0.6% acetic acid rather than bacteriostatic water, because the acidic diluent helps keep it in solution. The 1 mg vial is small by design, since study amounts are measured in micrograms. Store it at 2 to 8 °C once mixed.

Melanotan 1 is a linear 13 amino acid analogue of alpha-MSH, known generically as afamelanotide. Melanotan II is a cyclic 7 amino acid analogue with activity at more melanocortin receptors. PT-141 was developed from Melanotan II.

Yes. PT-141 is the research code for bremelanotide, a cyclic heptapeptide melanocortin receptor agonist. Our PT-141 is supplied for laboratory research use only.

SS-31, also known as elamipretide, is a synthetic tetrapeptide that concentrates in the inner mitochondrial membrane and binds cardiolipin. It is studied in mitochondrial dysfunction research.

The 10 mg vial suits short studies and first orders. The 40 mg vial is for ongoing protocols, but only choose it if you will use the reconstituted vial within the roughly 28 day storage window at 2 to 8 °C.

Selank is based on tuftsin, a fragment of immunoglobulin G, while Semax is based on the ACTH 4 to 10 fragment. They come from different parent molecules and are studied for different pathways, which is why many labs order both.

Yes. Both are available as 10 mL nasal sprays holding 10 mg at 1 mg per mL, as well as lyophilized vials.

The copper ion in GHK-Cu gives the powder and the solution a blue colour, which is normal and expected. A GHK-Cu vial with a white cake would suggest the copper complex is missing.

GLOW is a blend of GHK-Cu, BPC-157 and TB-500. KLOW holds the same three plus KPV.

No. Thymosin alpha-1 is a 28 amino acid immune modulator, while TB-500 is a fragment of thymosin beta-4, studied in tissue repair.

KPV is the tripeptide lysine-proline-valine, the last three amino acids of alpha-MSH, studied for anti-inflammatory activity.

Epitalon is a synthetic tetrapeptide with the sequence alanine, glutamic acid, aspartic acid and glycine, developed from research on epithalamin, a pineal gland extract.

DSIP, delta sleep-inducing peptide, is a nine amino acid neuropeptide isolated in 1977 and named for the slow-wave sleep it was reported to induce in rabbits.

Sterile water works for a single draw, but it has no preservative, so bacteria can grow once the stopper has been punctured. For a vial that will be used over several days, bacteriostatic water with 0.9% benzyl alcohol is the standard choice.

A U-100 insulin syringe holds 100 units per 1 mL, so 10 units equals 0.1 mL and 50 units equals 0.5 mL. Divide the peptide amount in the vial by the water added to get the concentration, then convert the volume you need into units.

The GHK-Cu Starter Kit includes one 50 mg GHK-Cu lyophilized vial, one 3 mL bacteriostatic water vial and one U-100 1 mL insulin syringe, packed in a single carton. It holds everything needed to reconstitute and draw from the vial.

Yes. Store the kit at 2 to 8 °C, since the peptide vial inside is best kept cold. The bacteriostatic water and syringe are fine at room temperature, but keeping the whole carton in the fridge is simpler.

Orders placed and paid before 3pm on a business day are sent out the same day. Later orders go out the next business day.
