Nextgenpeps (nextgenpeps.com) caught my eye on price, so I'm digging into the catalog, shipping and COA side before I'd put in any lab order. Main thing I want to know: are the COAs they publish batch/lot specific and actually tied to the exact items listed in the catalog right now, or are they just representative examples?
Same question on stock — does the catalog show current availability with exact vial and quantity specs, or are some items pre-order/backorder? And do the posted prices include shipping, handling, and any cold-chain or packaging fees, or do those show up at checkout?
Also curious where it ships from and typical transit time, whether tracking and customs documents come with it for domestic and international destinations, and if buyers can request lot-specific COAs and verify the third-party lab identity and date before ordering. If anyone's ordered, chime in.
