Red flags I've seen in 100+ vendor reviews

I went ahead and placed an order too after seeing this. My independent test results were interesting: - Janoshik HPLC: 97.2% purity - PeptidePure COA claimed: 98.8% So a 1.6% discrepancy on my batch. Less than the OP's but still consistently inflated. The product itself is good though — my endocrinologist actually commented that my GLP-1 levels looked consistent with proper semaglutide dosing (I get labs done monthly). At $129/vial it's a strong value proposition IF the actual purity stays in the 96-97% range. I just wish they'd be honest about their numbers.

Two independent tests both showing the COA inflated by 1.5-2.5% is a pretty clear pattern. The actual product quality is fine — 96.8% and 97.2% are both perfectly usable — but the intellectual dishonesty is a problem. I've seen vendors start like this and go one of two ways: 1. Community pressure leads them to adopt third-party testing and they become a solid option 2. They double down on in-house testing and eventually quality slips because there's no external accountability Hoping PeptidePure goes route #1. The pricing, shipping, and product quality (as independently verified) are all good. They just need to be honest about their numbers.
