The PepSource rep showing up to offer "replacements" is peak comedy. Two independent tests showing 43% and 58% of label claim, and their solution is "send us your order number." Here's what a legitimate vendor would do: 1. Immediately pull the affected batches 2. Send samples from those batches to a third-party lab 3. Publish the results publicly 4. Offer full refunds, not replacements 5. Identify and fix the manufacturing issue Until PepSource does all five of those things, they should not be trusted. I'm recommending they be added to the caution list.

We are adding PepSource to the caution list pending further testing. Two independent Janoshik results showing significant under-dosing (43% and 58% of label claim) is a serious quality concern. — We are willing to reassess if you provide: 1. Third-party lab results from Janoshik or another accredited lab for current inventory 2. A public explanation of your QC process 3. Evidence of corrective action Until then, members are advised to exercise caution and test any PepSource products before use.

I'll keep this thread updated. Already submitted my refund request. Let's see if they actually process it or if I need to do a chargeback. Main takeaway for everyone: TEST YOUR PEPTIDES. Even vendors with decent reputations can slip. A $120 Janoshik test could save you months of wasted time and hundreds of dollars on bunk product. It's the cost of doing business in this space.
