Tracking updates were accurate in transit but delivery took a little longer than the estimate.. still rec'd everything intact w/ COA included.
Consistent performance in our bench assays run after run and the documentation made it easy to log each lot without extra back-and-forth…
The glass vials feel heavy and uniform with no chips or stress lines at the crimp. Stopper seating looks clean under magnification. Exactly the container quality we want for peptide storage in the lab.
Every vial arrived with tamper-evident seals intact and no damage to the crimp.
Full stated quantity in every vial with minimal loss at the lyophilized cake. Labels have stayed legible through freezer storage and handling. Batch info on the COA matched the vial codes without any hunting. We have reordered twice now and the presentation has been consistent both times. For a peptide we keep on standing order that reliability matters!!
We switched our Melanotan 2 order to Scientipeptides and the vial crimp and stopper seal were noticeably better than our previous source. They also helped us track down a specific lot COA when procurement asked for it on short notice. The invoice formatting was very basic, but the product and documentation were solid and we are glad we made the switch!!
Glad we switched!!
Melanotan 2 COA showed low residual TFA/solvent, net peptide content vs gross mass was stated clearly, and the lot paperwork was in the box.
The lyophilised cake arrived intact with no clumping, padding kept everything secure in transit, and support handled a minor shipping snag smoothly. A bit more outer packaging than the order really needed but everything showed up fine and I would reorder for bench work.
Accurate product specs on the site matched the vial label and COA on arrival, no guesswork needed!!…
Melanotan 2 fine reordering.
Certificate of analysis, mass spec, and HPLC all supplied. This level of documentation is exactly what we need for reproducible research.
Melanotan 2 plus the broader Scientipeptides catalogue covers most of our research program needs and international shipping was handled smoothly end to end.
Melanotan 2 has been an excellent reference standard for our method development work.
Melanotan 2: in-house HPLC matched COA purity, quality glass vials.
Purity confirmed by our core facility. The vendor was responsive when we requested the raw HPLC file for our records.
Prompt, professional, and the product specification was accurate. Reordered for the continuation of our research program.
Fast turnaround and careful cold-chain packaging. The vials arrived intact with desiccant and the lot documentation we needed for our records.

FAQs
What are Scientipeptides used for?
All Scientipeptides products are sold for research use only. They are not intended for human consumption, therapeutic, or diagnostic use. Our peptides are designed exclusively for controlled laboratory research, educational studies, or analytical testing. Every product label and supporting document clearly reflects this compliance standard.
Who is eligible to purchase peptides?
Scientipeptides products are available to qualified researchers, laboratories, and educational institutions. Purchasers must confirm the products will be used for research purposes only.
How should peptides be handled and stored?
Lyophilized peptides should be stored at -20°C and protected from light and moisture. Once reconstituted, peptides should be used promptly and stored according to the documentation included with each product.
Why do peptide vials appear nearly empty?
Lyophilized (freeze-dried) peptides often appear as a thin film or small pellet at the bottom of the vial. The milligram amount stated on the label is verified by HPLC and mass spectrometry regardless of visual volume.
