DSIP | Peptides | 99% Purity | 5mg 10mg 15mg Vials | Lyophilized Powder

About Us

We are a peptide manufacturer with our own research laboratory and production line. We are committed to producing high quality research grade peptides of exceptional purity and consistency. We ensure strict quality control at every stage. The production process of lyophilized powder is mainly based on vacuum freeze-drying. Vacuum freeze-drying is used to maximize the activity and stability of the active ingredient, and the entire process from preparation to freeze-drying is carried out in our manufacturing facility, ensuring strict quality control, purity and consistency of each batch. Our commitment to excellence extends from the initial stages of peptide synthesis to packaging and delivery. We implement stringent quality control measures at every step to ensure that our products reach our customers in the purest, most consistent form.

DSIP (Delta sleep-inducing peptide) is a well-known neuromodulator and natural sleep-promoting nonapeptide with many other physiologic functions. It is typically found in the brain and easily passes the blood-brain barrier. It has been discovered and heavily studied for over 40 years.It has been used for the treatment of poor sleep, pain conditions, stress-related symptoms, low testosterone (via stimulation of LH), and even sometimes as an antioxidant and anti-cancer protein. It exhibits a pronounced stress protective action and decreases stress-induced metabolic and functional disorders in human and animal organisms exposed to a variety of stresses. It has also been shown in research to improve hormone levels and physical performance.

Whether you require small quantities for research and testing or large-volume orders for long-term cooperation, we are committed to providing stable supply, reasonable pricing, a wide variety of peptides, trusted quality, and reliable service. Moving forward, we will continue to uphold the principles of "Quality First, Honest Cooperation, and Long-Term Win-Win Partnership” to grow together with customers
