Buying Peptides Online: Ordering Questions
How do I order research peptides from AminoBlend?
Shop by category or search for the compound, choose the fill, and add it to your cart with any diluent or syringes you need. At checkout you confirm you are 18 or over and accept the research use terms, and the order is placed. No account is needed to browse the range or read a certificate first.
Which peptides should a new lab buy first?
Most first orders start with one well-documented compound and its diluent. BPC-157 is our most ordered repair peptide, the GHK-Cu Starter Kit puts a vial, bacteriostatic water and a syringe in one carton, and the kits and bundles range covers other ready-made sets. The peptides for sale overview walks through the range by research area.
Can I buy peptides near me instead of online?
Pharmacies and local shops do not stock research peptides. AminoBlend holds its range in Australian stock and sells online to researchers anywhere in Australia, so there is no local store to find: the same lots and certificates are available wherever your lab is.
Do you sell in bulk?
Yes. Labs and resellers buying in volume can request a written quote on the wholesale page, while single vials can still be bought through the normal shop.
Testing and certificates of analysis
How do I get the COA for my vial?
Read the lot number off the vial label and find the matching report in the COA library. If no report shows for that lot yet, send us the product and its lot code and we will email the certificate across.
Why does the lot number matter?
A certificate only describes the lot that was tested. If the number on your vial and the number on the report differ, that report says nothing about your vial. Our guide on reading a certificate of analysis explains the rest of the document.
Storage and reconstitution
What is bacteriostatic water used for?
It is sterile water containing 0.9% benzyl alcohol, used to dissolve freeze-dried peptide. The benzyl alcohol slows bacterial growth, so the same vial can be drawn from several times over roughly 28 days. We sell bacteriostatic water in 3 mL, 10 mL and 30 mL vials, each available with or without a syringe.
Can sterile water be used instead?
For a single draw, yes. Plain sterile water has no preservative, though, so once the stopper has been pierced it can support bacterial growth. If the vial will be drawn from across several days, bacteriostatic water is the usual pick.
When is 0.6% acetic acid used?
Some peptides dissolve poorly in neutral water and stay in solution better in a dilute acid. Labs working with those compounds use 0.6% acetic acid as the diluent. Check the solubility notes for the specific peptide before choosing.
How many units are in 1 mL on a U-100 syringe?
One hundred. That makes 10 units equal to 0.1 mL and 50 units equal to 0.5 mL. Work out the concentration first (milligrams in the vial divided by millilitres of diluent), then express the required volume in units. The peptide calculator does the arithmetic.
Questions about specific peptides
BPC 157 or TB-500: which should a lab order?
They are studied for different mechanisms, so neither is better in general. BPC-157 is a 15 amino acid peptide derived from a gastric juice protein, while TB-500 is a man-made piece of the larger protein thymosin beta-4. For a study comparing them, buy BPC-157 and TB-500 as separate vials. The BPC-157 and TB-500 blend only makes sense when a protocol already calls for both at a fixed ratio.
Why is GHK-Cu blue?
The bound copper ion colours both the powder and the solution blue. That is expected. A white cake in a GHK-Cu vial would suggest the copper complex is missing, so compare the lot against its certificate.
What is CJC-1295 without DAC?
Also called Modified GRF (1-29), it is a GHRH analogue without the drug affinity complex. Its half-life is around 30 minutes; the DAC version lasts roughly 6 to 8 days. It is the form most often paired with ipamorelin, which is why we also stock a CJC-1295 and ipamorelin blend.
Which MOTS-C size should I choose?
MOTS-C comes in 10 mg, 20 mg and 40 mg vials. The 10 mg suits short studies and first orders. Only go to 40 mg if the reconstituted vial will be used up within about 28 days at 2 to 8 °C.
What is SS-31 (elamipretide)?
Elamipretide, usually listed as SS-31, is a synthetic tetrapeptide that accumulates in the inner mitochondrial membrane and binds cardiolipin there. It is studied in mitochondrial dysfunction models.
Selank vs Semax: what is the difference?
They come from different parent molecules. Selank is an analogue of tuftsin, a fragment of immunoglobulin G. Semax is an analogue of the ACTH 4 to 10 fragment. Because they are studied for different pathways, many labs order both.
Do you sell peptide nasal sprays or capsules?
Yes, for a few compounds. Selank, Semax and DSIP are available as 10 mL nasal sprays as well as vials. BPC-157 and SLU-PP-332 are also sold as 60-capsule packs.
GLOW vs KLOW: how do the blends differ?
GLOW is a 70 mg vial combining GHK-Cu, BPC-157 and TB-500. KLOW adds KPV to those three, in an 80 mg vial.
Are thymosin alpha-1 and TB-500 the same thing?
They are not. Thymosin alpha-1 is a 28 amino acid peptide first isolated from thymus tissue and studied in immune research. TB-500 is a fragment of a different protein, thymosin beta-4.
What are KPV, Epitalon and DSIP?
KPV is lysine-proline-valine, the three residues at the C-terminal end of alpha-MSH, studied for anti-inflammatory activity. Epitalon is the tetrapeptide Ala-Glu-Asp-Gly, developed from work on the pineal extract epithalamin. DSIP (delta sleep-inducing peptide) is a nonapeptide first isolated in 1977.

Research Peptides FAQ Explained
Which Topics Does This Peptide FAQ Cover?
The answers on this page fall into groups: ordering, testing and certificates, storage and reconstitution, then short notes on individual compounds such as GHK-Cu, MOTS-C and SS-31. Each answer is kept to a few sentences, with a link onward when a full guide exists.
What Does Lyophilised Mean on a Peptide Vial?
Lyophilised means freeze-dried: the peptide was frozen and its water removed under vacuum, leaving a dry cake or loose powder at the bottom of the vial. In that state most sequences stay stable for long periods at minus 20 °C. The powder only becomes a liquid once a lab adds a diluent.
Bacteriostatic Water, Sterile Water or Acetic Acid: Which Is Which?
- Bacteriostatic water: sterile water with 0.9% benzyl alcohol, suited to a vial drawn from several times over about 28 days at 2 to 8 °C.
- Sterile water: no preservative, so it suits a single draw or same-day aliquoting.
- 0.6% acetic acid: a mild acid for basic or hydrophobic sequences that stay cloudy in neutral water.
How Do Milligrams, Millilitres and Syringe Units Relate?
Concentration is the milligrams of peptide in the vial divided by the millilitres of diluent added, so 5 mg in 2.5 mL gives 2 mg/mL. On a U-100 syringe, 100 units equal 1 mL, which makes 25 units a quarter of a millilitre. The reconstitution calculator converts between these figures for any vial size.
Where Do Certificate Questions Get Answered Fastest?
Most certificate questions are solved by the lot number on the vial: type it into the COA library and the matching report appears. If the lot has not been published yet, send the product name and lot number through the contact page and we will forward the report.
Which Questions Will Never Appear in This FAQ?
There is no answer here about doses, cycles or effects in people, because none of our compounds are sold for that. Questions in that territory get a reply pointing to the research use policy rather than advice.
Frequently Asked Questions
Where can I buy research peptides in Australia?
Buy them online from AminoBlend, which holds research peptides in Australian stock. The range covers recovery, growth hormone, metabolic, immune, skin, longevity and nootropic peptides, plus blends and lab supplies such as bacteriostatic water, and each lot's certificate can be read in the COA library before you order.
Are AminoBlend peptides lab tested?
Yes. Every lot is sent to an independent laboratory before it goes on sale, where mass spectrometry confirms identity and HPLC measures purity. The lot number on each vial label matches its certificate of analysis, and the reports are published in our COA library so you can check them before ordering.
What does research use only mean for peptides?
It means the products are supplied for laboratory and in-vitro research, not as medicines, supplements or cosmetics. They are not TGA approved and must not be used in people or animals. Buyers must be 18 or older, and by ordering they confirm the purchase is for research. Our research use policy has the details.
