Disappointing Reta and Tirza purchase, wouldn’t reorder!

I ordered Retatrutide 30 mg and Tirzepatide 30 mg from Andy Peps Studio after seeing their strong reputation and published testing history. Unfortunately, both products have been disappointing compared with similar products I’ve previously obtained from another supplier. The difference was noticeable enough that I’ve lost confidence in this purchase. I haven’t independently tested my specific vials, so I can’t claim they were underfilled, mislabeled, or chemically defective. However, my experience fell well short of expectations, especially given the reputation APS has built. Based on this order, I wouldn’t purchase from them again without stronger independent testing tied to the exact shipped batches and a satisfactory response to my concerns.

Ktechpeps Doxxed Me and Withheld My Refund

⭐ 1/5 Stars — Ktechpeps: Buyers Beware I initially thought Ktechpeps was one of the better vendors I’d dealt with. Their communication was great, prices were competitive, and I even recommended them to friends. Unfortunately, that changed completely. I placed multiple orders, including one on September 12 that sat in customs for weeks with no meaningful progress. After nearly a month of waiting, I was promised a refund. Things took a disturbing turn when I shared my honest shipping experience in their Telegram group. Despite claiming they welcomed transparency, their representatives became hostile, blamed me for speaking up, and then refused the refund I’d previously been promised because of my comments. The worst part? They publicly shared a screenshot containing my personal home address in their Telegram group and threatened to share it again in an even larger group. Shortly afterward, I was removed from their group. Let that sink in. A company I trusted with my personal information allegedly used that information against me simply because I spoke publicly about my experience. At this point, I no longer feel comfortable receiving products from this company. I’ve requested my money back and have disputed the payment. Customers deserve transparency, accountability, and basic respect for their privacy. Shipping delays happen, especially with international orders. But retaliating against customers, withholding promised refunds, and exposing their personal information is completely unacceptable. I strongly encourage anyone considering Ktechpeps to think carefully before trusting them with their money or personal information. This is my firsthand experience, and I have screenshots documenting what happened.

I have ordered many times and they as always delivered as promised. My results have been solid, The only thing keeping me from giving a solid 5 across the board is not having run third party testing myself. But my own results have brought me back again and again.
