Questions

Common questions about research peptides, ordering, and site standards.
01

What research peptides are available in the Helix Bio shop?

Knowledge Base

The Helix Bio shop carries a curated catalog of research-use-only peptides for laboratory study, including BPC-157, TB-500, Semaglutide, Tirzepatide, Ipamorelin, CJC-1295, PT-141, Melanotan II, GHK-Cu, Thymosin Alpha-1, Epithalon, Selank, Semax, and related compounds. Each listing shows current stock status, available vial sizes, and a linked certificate of analysis.
02

Are all Helix Bio products tested for purity and quality?

Knowledge Base

Yes. Every batch is verified through third-party HPLC and mass spectrometry testing before it is listed for sale, and the resulting certificate of analysis is made available at or before checkout so researchers can confirm purity and identity ahead of ordering.
03

What purity levels are standard for research peptides?

Knowledge Base

Reputable research peptide suppliers report purity of 98% or higher, with many premium compounds tested at 99%. Purity is confirmed by HPLC analysis and disclosed on each batch's certificate of analysis rather than estimated, so researchers can verify the figure independently.
04

How do I interpret the certificate of analysis (COA)?

Knowledge Base

A COA lists the batch number, measured purity by HPLC, molecular weight confirmation by mass spectrometry, and the testing date. Matching the batch number on the vial label to the COA on file confirms that the document corresponds to the specific vial received.
05

Do you offer custom peptide synthesis for specific research needs?

Knowledge Base

Custom synthesis availability depends on compound, quantity, and lead time. Researchers with a specific sequence or scale requirement should reach out through the shop's support channel to confirm feasibility, pricing, and turnaround before placing a standard order.
06

What are proper storage instructions for research peptides?

Knowledge Base

Lyophilized (unreconstituted) peptides are generally stored frozen or refrigerated, away from light and moisture, until they are needed. Once reconstituted, most peptides should be kept refrigerated and used within the timeframe noted on the product page or COA.
07

How should I reconstitute lyophilized peptides for laboratory use?

Knowledge Base

Reconstitution typically involves adding bacteriostatic or sterile water slowly down the side of the vial to avoid disturbing the lyophilized powder, then gently swirling rather than shaking. Exact solvent volume varies by compound and is listed on the individual product page.
08

What is the shelf life of research peptides?

Knowledge Base

Unopened, properly stored lyophilized peptides typically remain stable for one to two years, while reconstituted solutions have a much shorter usable window, often two to four weeks under refrigeration. Product pages and the COA note batch-specific stability guidance.
09

Can peptides be damaged during shipping or storage?

Knowledge Base

Yes. Heat exposure, repeated freeze-thaw cycles, and prolonged light exposure can all degrade peptide integrity. Helix Bio ships with cold-chain packaging appropriate to the compound, and researchers should transfer vials to proper storage promptly upon arrival.
10

Should I aliquot peptides after reconstitution?

Knowledge Base

Aliquoting reconstituted peptide into single-use portions reduces repeated freeze-thaw cycling and contamination risk, which helps preserve potency across a longer study. This is standard laboratory practice for any peptide expected to be used across multiple sessions.
11

What documentation comes with laboratory peptide purchases?

Knowledge Base

Each order includes an invoice and access to the batch-specific certificate of analysis. Institutional buyers can additionally request a wholesale account with consolidated invoicing for recurring or purchase-order-based procurement.
12

Can I order research peptides in different quantities?

Knowledge Base

Most compounds are available in multiple vial sizes, and select peptides offer bundle or bulk pricing for larger research studies. Available sizes and quantity-based pricing are shown on each product listing within the shop.
13

Are COAs available before ordering to verify product specifications?

Knowledge Base

Yes. Certificates of analysis are linked directly from the product page, so researchers can review purity, batch number, and testing method before completing a purchase rather than waiting until after the order ships.
14

How do I find specific peptides in your catalog?

Knowledge Base

The shop can be browsed by category, such as GLP-1 compounds, tissue-repair peptides, or cognitive research peptides, or searched directly by compound name. Filtering by stock status also narrows results to what is currently available.
15

What information is included on product pages?

Knowledge Base

Each product page lists the compound name, available vial sizes, current price, stock status, a linked certificate of analysis, and relevant handling notes such as recommended storage and reconstitution guidance.
16

Are all products manufactured in the USA for research compliance?

Knowledge Base

Helix Bio sources and distributes from within the USA, and each batch is tested domestically before listing. Country-of-origin and testing details for a specific compound can be confirmed on request or within the linked COA.
17

What does "Research Use Only" mean for these products?

Knowledge Base

Research Use Only (RUO) means a compound is intended strictly for laboratory and scientific research, not for human or veterinary consumption, diagnostic, or therapeutic use. RUO products are not evaluated by the FDA for safety or efficacy in those contexts.
18

Do research peptides require special handling or safety precautions?

Knowledge Base

Yes. Standard laboratory safety practices apply, including gloves, a clean work surface, and sterile technique during reconstitution. Peptides should be handled by trained research personnel in an appropriate laboratory setting, consistent with their RUO status.
19

Can I use these peptides for any purpose outside of research?

Knowledge Base

No. Products sold through the Helix Bio shop are labeled Research Use Only and are not intended, tested, or approved for human consumption, self-administration, or any clinical use. They are sold exclusively for qualified laboratory research.
20

Are your products approved by the FDA or other regulatory agencies?

Knowledge Base

No. Research Use Only peptides are not FDA-approved for human use and are not marketed as drugs, supplements, or cosmetics. They are sold strictly as laboratory research chemicals, consistent with their labeling and intended use.
