How many units to draw?

Enter vial strength, BAC water volume and your desired dose - get the exact units to draw on a U-100 insulin syringe, with the concentration and volume-per-dose math shown step by step.

  • Vial mg + BAC water + dose → exact U-100 units
  • Start from a peptide preset or enter values by hand
  • Shows concentration (mg/ml) and volume per dose

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%.

What peptides does New-U sell?

The catalog includes 50+ research compounds across healing & recovery (BPC-157, TB-500, KPV), HGH & growth-hormone secretagogues (Sermorelin, Ipamorelin, CJC-1295, HGH 191aa), fat-loss & metabolic (Semaglutide, Tirzepatide, Retatrutide, AOD-9604), longevity (Epitalon, MOTS-C, NAD+, SS-31), skin (GHK-Cu, Argireline), tanning & libido (Melanotan-2, PT-141), muscle (IGF-1 LR3, MGF), and cognitive (Semax, Selank, Dihexa).

Where can I learn about a specific peptide?

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?

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?

Yes. Bacteriostatic water (BAC water) is available as an add-on for peptide reconstitution. See the step-by-step guide at new-u.io/blog/how-to-reconstitute-peptides, or use the free reconstitution calculator at new-u.io/tracker/calculator to work out how many units to draw.
