is Wuhan Wansheng still legit or am i missing something
ok so i placed an order with these guys back on the 14th, retatrutide, been comparing landed cost across vendors for a while and they were sitting pretty comfortably in my spreadsheet. price per mg was solid enough that i pulled the trigger after sitting on it for a few weeks. package finally showed up and i was actually pumped to get a COA done... and the score comes back basically in the toilet. 65ish range. i've stress-tested a lot of vendors at this point and that number would normally send me straight to the trash column but i paid non-trivial money for this and shipping wasn't cheap either so the landed cost math just turned real ugly real fast. thing is, used them once before (tesamorelin, probably 8 months back) and it was fine. nothing flashy but it cleared testing no problem and i didn't feel like i got robbed. so this feels like a step backward?? not sure if they changed suppliers or something shifted on their end but something clearly did. i dont want to blast them as outright garbage based on one bad pull but i also cant just absorb this loss and pretend the data doesnt say what it says. been going back and forth on whether to dispute or just chalk it up and move vendors entirely. most of the recent forum chatter i can find on them is older... nothing recent. which honestly might be the answer right there 🙃 so, anyone ordered from Wuhan Wansheng recently? specifically reta or tirz? getting similar COA results or did i just get a bad batch? what would you do here

65 is a meaningful drop from what that vendor used to post. not catastrophic for every compound but for reta specifically, purity variance matters more than people give it credit for. if you paid and the product doesn't test clean, worth documenting and reaching out to them directly before escalating. some vendors will actually respond when you attach a COA. some won't. you'll have your answer either way. would sit on reordering until there's fresher community data on their current batches
this is actually really helpful to see, i was literally about to pull the trigger on an order from them this week. been trying to figure out which vendors are worth trusting for a first buy and they kept showing up in older threads with decent feedback. can i ask, which lab did you send it to for testing? janoshik or somewhere else? trying to understand the testing side of this better before i order anything. i've read about HPLC vs MS and honestly still sorting out what a "good" number looks like in practice vs just knowing 65 is bad. thanks for posting this either way. saved me from probably making the same mistake
reta from a sketchy COA source is not something i'd mess with personally. the half-life on that thing is long enough that a bad batch isnt just a wasted pin, it's a wasted couple weeks of whatever protocol you're running. i had a vendor issue earlier this year, different company, and the impact showed up in my Oura data before i even got the COA back honestly. deep sleep cratered, recovery score was a mess. could be coincidence but i've seen clean reta from a verified source and the sleep architecture difference was pretty clear around 90 min post-pin timing. not saying that's diagnostic but 65 on the bench is a red flag regardless
i haven't touched Wansheng in about a year so cant speak to their current batches. switched off after a tesamorelin order that tested fine but just felt... off. hard to quantify, just wasnt seeing what i expected at reasonable concentrations. for context i run pretty steady protocols so i notice when something isnt performing. could be unrelated but combined with what youre posting i'm not rushing back. if the COA is that soft id honestly just move on. the time cost of chasing a vendor dispute usually isnt worth it unless the order was big enough to fight for
oh nice, 65. real inspiring confidence there 🙃 i'm deep in a tirz log right now and let me tell you, sourcing matters in ways you only fully appreciate when you switch to something that actually tests clean. food noise went from background hum to basically silent within like 5 days of switching vendors last cycle. could be batch variance, could be my head, who knows. point being, the cost-per-mg math only makes sense if the mg is real. a 65 on reta is basically buying expensive solvent with extra steps. id cut the loss and rerun the numbers on a vendor with recent third party data before the next order
worth noting, a 65 range score on HPLC alone doesn't tell you everything. depending on methodology that could be a purity issue, degradation, or filler/related substances throwing off the peak integration. would want to know if they ran MS alongside it to confirm identity at minimum. the other thing nobody talks about with vendors at this tier is endotoxin. LAL testing isn't standard in most community COA requests and a product can pass basic purity and still have an endotoxin load that's a problem. just flagging it. bench-top HPLC has real limits here
