An independent, category-by-category comparison of Purgo Labs and AIO Peptides — covering purity standards, COA transparency, pricing, product selection, and shipping.
Our Verdict
AIO Peptides markets US-manufactured peptides as a key differentiator and has excellent customer service reviews. However, Purgo Labs offers a broader catalog, more transparent per-batch COA documentation, and competitive pricing. For researchers prioritizing product breadth and rigorous testing documentation, Purgo Labs is the stronger choice.

AIO Peptides' primary differentiator is their claim of US-manufactured peptides — a meaningful distinction if verified, as domestic manufacturing can provide tighter quality control and faster regulatory oversight. Purgo Labs uses US-based fulfillment with cGMP-compliant manufacturing. For researchers where domestic manufacturing is a requirement, AIO Peptides' claim is worth investigating directly.
AIO Peptides has exceptional customer service reviews — Trustpilot reviewers describe it as 'the best customer service I've ever received.' This is a genuine competitive advantage. Purgo Labs offers solid email support and detailed product documentation, but AIO Peptides appears to excel in direct customer interaction.
Purgo Labs carries 30 compounds including the full GLP-1 class, NAD+, and proprietary blends. AIO Peptides' catalog focuses on core US-manufactured peptides with less breadth in the metabolic/GLP category. On pricing, both are competitive — Purgo Labs' 15% discount code (HEALTH) provides a clear savings advantage.
AIO Peptides markets US-manufactured peptides as their core differentiator. This claim is stated on their website but independent verification is difficult. If domestic manufacturing is a research requirement, contact AIO Peptides directly to request documentation of their manufacturing facility.
AIO Peptides has strong Trustpilot reviews (4.9, 476 ratings) with consistent praise for product quality and customer service. They appear to be a well-regarded supplier with a focus on quality control. Their catalog is narrower than Purgo Labs but covers core peptides well.
AIO Peptides' customer service is consistently rated as exceptional in reviews. This is their clearest competitive advantage. Purgo Labs offers responsive email support, but AIO Peptides appears to have an edge in direct customer interaction quality.
