Frequently asked

Peptides are short chains of amino acids that act as signaling molecules in the body. They bind to specific receptors on cells, triggering biological responses related to recovery, growth, and cellular optimization. Our pharmaceutical-grade peptides are synthesized to exacting standards and backed by peer-reviewed research demonstrating their efficacy in muscle recovery, bone density, and metabolic function.

Yes. Every product undergoes rigorous third-party testing for purity, potency, and sterility. We source raw materials from certified suppliers and maintain GMP-equivalent manufacturing standards. Each batch includes a certificate of analysis detailing HPLC purity, endotoxin levels, and microbial testing results.

Our Protocols section outlines evidence-based stacks for specific goals: recovery, muscle growth, bone health, and metabolic optimization. Start by identifying your primary objective, then review the recommended peptide and dosing protocol. If you're new to peptides, we recommend beginning with a single compound before stacking. Consult our Science section or reach out to Support for personalized guidance.

Dosing varies by peptide and goal. Most recovery peptides are dosed at 100–300 mcg per injection, typically administered subcutaneously 1–2 times daily. Growth-focused peptides may require higher doses or different timing. Every product page includes detailed dosing guidelines and a link to peer-reviewed studies. Always start at the lower end of the range and adjust based on individual response.

Unopened vials should be stored at 2–8°C (refrigerated). Once reconstituted with bacteriostatic water, peptides remain stable for 30 days when refrigerated. Do not freeze reconstituted peptides. Store away from direct light and heat. Our packaging includes detailed storage instructions; follow them to maintain potency.

We currently ship to the continental United States. International orders are not available at this time. Check back for updates on expanded shipping options.

We stand behind the quality of every product. If you receive a vial that fails third-party testing or arrives damaged, we will replace it at no cost. Unopened, unused products may be returned within 30 days of purchase for a full refund. Opened or reconstituted peptides cannot be returned for safety and regulatory reasons.

Peptides are legal to purchase and possess in the United States for research purposes. However, regulations vary by jurisdiction and use case. We sell our products for research and educational purposes only. It is the buyer's responsibility to ensure compliance with local, state, and federal laws. Consult a healthcare provider before use.

Orders placed before 2 PM ET ship the same business day via USPS Priority Mail Express. Delivery typically occurs within 1–2 business days. You will receive a tracking number via email upon shipment. For expedited handling, select Priority Mail Express at checkout.

Yes. Many users combine peptides to target multiple goals simultaneously—for example, pairing a recovery peptide with a growth-focused compound. Our Protocols section includes evidence-based stacks for common combinations. Start with single compounds first to assess tolerance, then layer in additional peptides as needed. Always consult the Science section for synergy data.

Peptides can interact with certain medications and may not be suitable for individuals with specific health conditions. We strongly recommend consulting a healthcare provider—ideally one familiar with peptide research—before starting any protocol. Do not use peptides if you are pregnant, nursing, or have active cancer.

Response timelines vary. Recovery peptides may show effects within 2–4 weeks (improved sleep, reduced soreness). Growth-focused peptides typically require 8–12 weeks to demonstrate measurable changes in body composition or strength. Track metrics relevant to your goal: sleep quality, workout recovery, strength gains, or body composition. Keep a simple log to monitor progress.
