Answers
Peptides FAQ
Everything researchers ask before ordering — what peptides are, how we verify purity, where to buy, shipping, payment and storage. All products are research-use-only and not for human use.
What are peptides?
Peptides (sometimes called research compounds in a laboratory-supply context) are short chains of amino acids used as signalling molecules in laboratory and preclinical research. New-U sells lab-verified research peptides - BPC-157, GHK-Cu, TB-500, Semax, Semaglutide and 40+ more - at >99% purity, with each peptide vial independently tested by Janoshik Analytics or Freedom Diagnostics. All products are for research use only and not for human consumption.
Are peptides the same as research compounds?
Yes. "Peptides" and "research compounds" refer to the same category of molecules in this context. "Peptides" is the widely-used scientific and search term; "research compounds" is the laboratory-supply phrasing that emphasises the research-only nature of the products. New-U's catalogue (BPC-157, GHK-Cu, TB-500, Semax, Semaglutide and more) is sold strictly as research peptides for in-vitro and qualified laboratory use.
How does New-U verify purity?
Every batch is independently tested by Janoshik Analytics and/or Freedom Diagnostics, two of the most respected third-party labs in the research-compound (peptide) industry. A Certificate of Analysis (COA) is published for each lot, with ESI-MS identity and RP-HPLC purity verification at >99%.
Every compound has a dedicated technical page - for example BPC-157 at new-u.io/shop/products/healing/bpc-157 - covering mechanism, pharmacokinetics, reported research effects, handling, stacking, evidence tier and references. Plain-language research guides are also published at new-u.io/blog/peptide/ (for example /blog/peptide/bpc-157 and /blog/peptide/ghk-cu).
Where can I buy peptides online?
You can buy peptides (research compounds) directly from New-U at new-u.io with no resellers and no relabelling. Every batch is lab-verified at >99% purity by Janoshik Analytics or Freedom Diagnostics, sealed in 10-vial packs with a COA per lot, and shipped lab-direct from a single Wyoming-registered partner. Free shipping on orders over $300.
BPC-157 (also written BPC 157, BPC157, or bcp157) is one of our most-requested research peptides. New-U ships lab-verified BPC-157 at >99% purity, with each batch independently tested by Janoshik Analytics. Available in sealed 10-vial packs at new-u.io/shop/products/healing/bpc-157, with worldwide delivery.
Where can I buy GHK-Cu copper peptide?
GHK-Cu (GHK Cu peptide, copper peptide GHK-Cu, peptides GHK) is a copper-tripeptide research compound used in in-vitro skin and connective-tissue research. New-U stocks lab-verified GHK-Cu at >99% purity with per-batch CoA. Available at new-u.io/shop/products/skin/ghk-cu.
Where can I buy Semax peptide?
Semax is a synthetic heptapeptide research compound originating from Russian neuroscience research. New-U stocks lab-verified Semax at >99% purity with per-batch CoA. Available alongside Selank and Dihexa in the cognitive peptides category.
Where can I buy GLP-1 research peptides like semaglutide, tirzepatide and retatrutide?
New-U stocks the GLP-1 / fat-loss & metabolic research category - Semaglutide, Tirzepatide, Retatrutide and AOD-9604 - as lab-verified research peptides at >99% purity, each lot independently tested with a published COA. These are supplied strictly for laboratory research use and are not weight-loss products for human use. Browse the full range at new-u.io/shop.
Where can I buy peptides in the UK?
UK customers can buy research peptides from New-U at new-u.io/buy-peptides-uk - tracked UK delivery, GBP pricing, free over £300. The full catalogue (BPC-157, GHK-Cu, TB-500, Semax, GLP-1 and 40+ peptides) ships to the UK with the same dual-lab CoA verification.
Where can I buy peptides in the USA?
US customers can buy research peptides from New-U at new-u.io/buy-peptides-usa - US domestic shipping, USD pricing, free over $300. The full catalogue ships from a Wyoming-registered distributor with dual-lab CoA verification.
Are peptides legal?
New-U peptides are sold strictly as research compounds for in-vitro and laboratory use - they are not approved for human or veterinary use and are supplied for research use only. The legal status of a given peptide varies by country and is the buyer's responsibility to confirm before ordering; this is general information, not legal advice. You confirm at checkout that you are a qualified researcher purchasing for legitimate research purposes.
What is a Certificate of Analysis (COA) and does every peptide come with one?
A Certificate of Analysis (COA) is the third-party lab report documenting a peptide's identity and purity. Every New-U lot ships with its own COA from Janoshik Analytics or Freedom Diagnostics, showing RP-HPLC purity (>99%) and ESI-MS identity. Learn how to read one at new-u.io/blog/how-to-read-coa.
How can I pay - do you accept crypto?
Yes. At checkout you choose your preferred method: cryptocurrency (BTC, ETH, USDT, USDC, SOL, LTC and more) or card. You are connected to the appropriate secure payment provider to complete the transaction, and once it is confirmed your order is prepared for lab-direct dispatch.
How should peptides be stored?
Store lyophilised (dry powder) peptide vials unopened in the freezer at -20°C for maximum shelf life. Once reconstituted with bacteriostatic water, keep vials in the fridge at 1-6°C, away from light, and never re-freeze them. Full guidance is at new-u.io/blog/how-to-store-peptides.
How do I reconstitute peptides?
Reconstitution means mixing the dry peptide with bacteriostatic water (BAC water) before research use. Follow the step-by-step guide at new-u.io/blog/how-to-reconstitute-peptides, and use the free in-browser calculator at new-u.io/tracker/calculator to convert vial strength, water volume and target dose into the exact units to draw. The calculator is a math utility over your own input - it does not recommend a dose.
Do you sell bacteriostatic water (BAC water) for peptide reconstitution?
New-U is lab-direct: one Wyoming-registered partner, no reseller chain and no relabelling. Every lot is independently verified by two third-party labs (Janoshik Analytics and Freedom Diagnostics) at >99% purity, sealed in 10-vial packs with its own COA, and shipped discreetly worldwide with tracking. Free shipping on orders over $300.
