Here you'll find answers to common questions.
Every vial we sell comes from a lab that follows current Good Manufacturing Practices (cGMP). That means each step of production is documented and controlled. Before a batch is released, it’s tested by independent third-party labs for purity, identity, and sterility. Certificates of analysis are available so you can see the exact test results.
Yes. The labs we work with use ISO-certified clean rooms where air quality, equipment, and handling procedures are tightly regulated. Staff are trained to pharmaceutical-grade standards. This ensures the peptides are produced in an environment that minimizes contamination risks.
Peptides in lyophilized (freeze-dried) form are stable at room temperature for transport. Once you receive them, refrigeration is recommended to maintain long-term integrity. We package every order securely to prevent damage and ship promptly, so your vials arrive in optimal condition.
We operate under strict in-house protocols that follow current Good Manufacturing Practices (cGMP). That means our team oversees the entire process from sourcing raw amino acids to the final lyophilized vial. Nothing is outsourced or repackaged. This gives us full control over purity, consistency, and sterility, and it’s why we can stand behind every single vial we ship.
Store them in the refrigerator, away from direct light and heat. If you need to keep them longer, some peptides can be stored frozen. Each vial comes with clear handling instructions so you know the proper conditions for stability.
The strongest proof is transparency. For every peptide, we can provide certificates of analysis, manufacturing documentation, and references to the published scientific research behind it. If you ever have questions, we’ll show you the data rather than ask you to take our word for it.
The difference is transparency. Most sites give you a product name and a price. We provide full batch testing, lab documentation, and direct access to certificates of analysis so you don’t have to guess what you’re getting. When you order from us, you know exactly what’s in the vial, where it was made, and how it was verified.
“NAD+ has completely changed my energy baseline in a way I did not think was possible anymore. Within the first week I noticed a clarity and steadiness that I had not felt in years. By week three the cognitive improvements were obvious to people around me. Exceptional purity and fair pricing not found elsewhere.”
“Mental clarity. Immediately noticeable.”
“Running NAD+ alongside NMN and Resveratrol as a comprehensive longevity protocol. The quality of this NAD+ is clearly superior to what I was using before — cellular energy response is more pronounced and more consistent batch to batch. COA documentation every single order.”
“Best investment in my health.”
“Started for energy and cognitive support. Got that plus better mood, better sleep architecture, and faster exercise recovery. Independent lab testing is what made me choose this source over alternatives I was seriously considering.”
“Energy transformation. Period.”
“Six weeks into a high-dose NAD+ protocol and the cellular energy difference is something I can feel and measure. Workout recovery is faster, cognitive performance is more consistent, and my sleep tracker confirms improved deep sleep stages.”
“Cognition sharpened immediately.”
“Using NAD+ as the cornerstone of a longevity-focused protocol alongside other cellular support compounds. Quality from this source is clearly superior to what I was using before. COA on every batch confirms the purity that makes the results possible.”
“Using NAD+ from this source as the foundation of a comprehensive longevity protocol for nine months. Cellular energy response is consistent batch to batch and cognitive and physical improvements have compounded progressively. Quarterly bloodwork reflects improvement in markers associated with NAD+ metabolism. Permanent source.”
“Cellular energy restored.”
“Running NAD+ alongside NMN and pterostilbene for comprehensive NAD pathway support. Quality of this NAD+ is clearly superior based on response — more pronounced and more consistent than what I used previously. COA documentation confirms what the results reflect.”
“Tried three different NAD+ sources before finding Peptides San Jose. Difference in cellular response quality from independently verified pharmaceutical grade material is significant and immediately apparent. Cognitive clarity, sustained energy, and exercise recovery all improved in a way cheaper sources never produced.”
“Clarity restored completely.”
“Using NAD+ for post-illness fatigue support alongside other interventions. Energy recovery has been the most significant contributor to my improvement and NAD+ from this source is clearly the most impactful addition. COA documentation made me comfortable using high doses.”
“Three years of NAD+ supplementation from various sources and this is the first one that produced bloodwork-confirmed improvements in markers associated with NAD+ metabolism. Difference between verified pharmaceutical grade and lower-purity alternatives is measurable on a blood panel. Peptides San Jose provides the documentation to confirm which category their product is in.”
“Energy changed permanently.”
“Second year of NAD+ from this source. Improvements in cognitive performance, energy regulation, and exercise recovery have been progressive and continue building. COA documentation is consistent and comprehensive with every order. Best source I have found after extensive comparison.”
“Using high-dose NAD+ under medical supervision as part of a comprehensive longevity protocol. Quality from this source is what my integrative physician specified — independently third-party verified at pharmaceutical grade. Bloodwork response over six months confirmed that NAD pathway improvements are real and measurable.”
“Foundation of my longevity stack.”
