Purity & Testing
Core Peptides provides batch-specific COAs with HPLC testing for every product, with purity typically 98-99%. Third-party testing is conducted on a rotating basis. Amino Asylum provides COAs for most products, but documentation consistency has been a point of community feedback. HPLC purity ranges from 96-99%. For researchers requiring reliable purity documentation, Core Peptides is significantly ahead.
Pricing
Amino Asylum offers some of the lowest prices in the market. BPC-157 (5mg) at $29.99 vs Core Peptides at $38.99 is a meaningful difference. Amino Asylum also runs frequent sales and offers pre-mixed formulations. Core Peptides counters with competitive promotional pricing and a lower effective cost when factoring in their frequent promotions. The sticker price advantage goes to Amino Asylum, but value (quality per dollar) favors Core Peptides.
Shipping
Core Peptides offers same-day shipping on orders before 1 PM EST with 2-4 day transit and free shipping over $175. Amino Asylum ships within 1-3 days with transit times that can range from 3-7 days, with inconsistency being a noted concern. Free shipping threshold at Amino Asylum is lower ($100). For predictable delivery timelines, Core Peptides is more reliable.
Product Range
Amino Asylum offers 100+ products including pre-mixed formulations versus Core Peptides' 75 products. Amino Asylum's wider catalog includes more compound categories. However, Core Peptides' catalog is carefully curated with detailed product information and research resources for each listing. The trade-off is breadth (Amino Asylum) vs depth of information (Core Peptides).
Customer Support
This is the largest gap between these vendors. Core Peptides offers email, live chat, and phone support with response times under 3 hours and is known for knowledgeable assistance. Amino Asylum relies primarily on email and social media with response times ranging from same-day to several days. For researchers who value accessible, responsive support, Core Peptides is the clear winner.
Our Verdict
Core Peptides is the better choice for researchers who prioritize product documentation, customer support, and consistent quality. Amino Asylum is better for budget-conscious researchers who need a wide product range and are comfortable independently verifying product quality. The quality gap between these vendors is meaningful — Core Peptides scores nearly a full point higher overall (8.8 vs 7.9).
