A COA (Certificate of Analysis) is an analysis certificate issued by an independent laboratory, attesting to the purity and chemical identity of a product batch.
Janoshik Analytical, a recognized independent laboratory in the industry, specialized in HPLC and LC-MS chromatography analysis.
On every product page, as well as in the full list available on our quality page.
≥98% across our entire catalog, verified by HPLC on every batch.
Compare the batch number printed on your vial with the one shown at the top of the corresponding COA document.
Contact us with the batch number printed on your vial — we will send you the corresponding document.
Our peptides are packaged under the BioPep brand and are systematically tested by an independent third-party laboratory before being offered for sale.
Every vial carries a unique batch number, which makes it possible to precisely retrieve the certificate of analysis corresponding to its production.
Inject bacteriostatic water slowly along the wall of the vial, without aiming directly at the powder, then gently roll the vial between your hands — never shake it.
Bacteriostatic water, available in our reconstitution kit or separately on the site.
Shaking too vigorously can damage the peptide's fragile structure. A gentle, circular motion is enough to dissolve the powder.
Use our interactive dosage calculator, which automatically converts your concentration into units readable on a U-100 syringe.
Generally 28 days refrigerated (2-8°C) after reconstitution — the exact duration may vary by compound, check the corresponding product page.
This is generally not recommended: freeze/thaw cycles can alter the peptide's structure once in solution.
Away from light and heat. Refrigerated storage extends the stability of the lyophilized powder, although it is designed to remain stable at room temperature during transport.
A vial of bacteriostatic water, a sterile syringe and an alcohol wipe — everything is included in our reconstitution kit.
This label indicates that the product is intended exclusively for laboratory research use, and not for human or animal consumption.
No. Our products have not gone through a market authorization process and are never presented or sold as medicines.
The sale of research peptides for laboratory purposes is governed by current regulations. See our dedicated article on the legal framework for an up-to-date overview — this content is informational, not legal advice.
Yes, access to the site is restricted to adults, verified as soon as you arrive on the site.
No, these products are sold exclusively for laboratory research use, outside of any context of human or animal administration.
No. We are not qualified to give medical advice, and no content on the site should be interpreted as such.
We monitor regulatory developments and withdraw from sale any compound whose status shifts toward restriction.
No, no justification is currently required when ordering — the commitment to respect the stated research use is the buyer's responsibility.
26 research peptides across 7 categories, plus 4 accessories (bacteriostatic water, syringes, alcohol wipes, complete kit).
Use the filter categories at the top of the catalog (weight loss, recovery, muscle growth, anti-aging, skin & beauty, focus & cognition, wellness) to quickly target the relevant compounds.
A molecule that activates a cellular receptor, a bit like a key turning in a lock to trigger a specific response.
Two families of compounds studied for growth hormone secretion, but acting on different receptors — GHRH mimics the natural signal, while GHRP acts through the ghrelin receptor.
A compound studied for its simultaneous activity on several distinct receptors (for example GIP, GLP-1 and glucagon for retatrutide), as opposed to a single or dual agonist.
The available dosage corresponds to the amount of active ingredient contained in the vial (in mg) — the choice depends on the concentration you want to obtain after reconstitution, which you can calculate with our dedicated tool.
Compounds from our catalog that are temporarily unavailable. You can leave your email on their page to be notified as soon as they're back.
Yes, our catalog also includes a few small research molecules (such as 5-Amino-1MQ), in addition to classic peptides.
By order of popularity within each category, with accessories grouped at the end of the catalog.
Yes, contact us via Telegram or email with your suggestion — we regularly consider adding new products.
