In the Biohacking and Longevity community, data is everything. But your data is only as good as your inputs. If your reagents are impure, your results are void. Over the last month, we have analyzed the catalog, pricing, and testing protocols of three major peptide vendors: Ascension Peptides, Tydes, and Prime Peptides. Here is how they stack up for researchers looking to stock their labs with GLP-1s, Growth Hormone secretagogues, and recovery agents. 1. The Criteria We judged these vendors on three metrics: - Purity Validation: Do they offer up-to-date HPLC/MS reports? - Catalog Depth: Do they have the latest GLP-1 and HGH compounds? - Value for Research: Cost per milligram after community discounts. 2. The Breakdown Ascension Peptides (The Value Leader) Ascension stands out immediately for its pricing structure. They carry the heavy hitters like Tirzepatide and Semaglutide at competitive rates. Their CJC-1295/Ipamorelin blend is a standout for efficiency in testing. - Pros: Best discount code (20%), high transparency, excellent for bulk orders. - Cons: Stock can fluctuate due to high demand. Tydes (The Innovator) If your research involves the absolute newest compounds, Tydes is the winner. They are one of the reliable sources for Retatrutide and newer sleep-modulating peptides like Epitalon. - Pros: Cutting-edge catalog, rigorous endotoxin testing. - Cons: Slightly more expensive than Ascension, but justified for novel compounds. Prime Peptides (The Standard) Prime is the "old reliable." They excel with standard fragments like AOD-9604 and BPC-157. Their packaging and lyophilization process ensure long shelf-life, which is vital for long-term studies. - Pros: Consistent batch quality, professional presentation. - Cons: Lowest discount tier (10%) of the three. 3. The Verdict: Which One Should You Choose? 🏆 Overall Winner: Ascension Peptides For the majority of our community members setting up their research protocols, Ascension Peptides offers the best balance of purity and price. The 20% OFF code makes a significant difference when purchasing higher-cost metabolic agents like Tirzepatide, allowing for more extensive research on a budget.
