Because you failed to send any instructions or details about how to use the product or mix the product I put the entire compound into the water solution wasting over $100 and getting zero results. I’m very disappointed!!!

Hi Amber, we're truly sorry — clear product documentation should have arrived with your order, and it didn't. That miss is on us. Because our products are supplied strictly for laboratory research use, we can't discuss preparation here, but our team can provide COAs and reconstitution/storage documentation for research purposes. We'd like to make this right with a refund or replacement of your order — no conditions attached. Please email [email protected] with your order number and "Trustpilot – Amber" in the subject, and we'll take care of it promptly. If we're able to make this right, we'd be grateful if you'd consider updating your review. — The Peptidic. Team

My experience with Peptidic has been great because the quality of their peptides is great, their prices are well below the others and their shipping is free and it is fast, it always comes earlier than expected. The customer support team is just above and beyond as far as communication and kindness. I really like this company for my research peptides. I will always go here for them.

Peptides arrived within a week. I’m taking one star off because the Retatrutide I ordered is 20 mg and comes in a bottle that’s not big enough to add 4 ML of bac water to reconstitute, which is what was recommended by the health professional I found Retatrutide through, so it’s hard to know the exact dose you end up getting per injection. Otherwise seems to be a good service.

Hi Stephanie, Thank you for taking the time to leave a detailed review — we’re glad to hear your order arrived quickly. I just wanted to clarify one important point regarding Retatrutide 20 mg reconstitution , as there seems to be a small misunderstanding that can easily cause confusion. For a 20 mg Retatrutide vial, you do not need to add 4 mL of bacteriostatic water. The recommended and standard protocol is 2.0 mL, which results in a 10 mg/mL concentration. This concentration is intentionally chosen because it makes dosing very straightforward: - 10 units = 1 mg - 20 units = 2 mg - 50 units = 5 mg Our vials are designed to safely accommodate up to ~3 mL, which is the industry standard for this peptide format. Adding 4 mL would lower the concentration to 5 mg/mL, making dosing math more complex and is not the recommended protocol for this vial size. Because the mention of needing 4 mL may unintentionally mislead other researchers and raise concerns about vial size, we kindly ask if you would consider updating or adjusting your review to reflect the correct protocol. Warm regards, Peptidic Support

I’ll commend you on your speedy delivery but that’s about it. The order that was delivered was a bottle with what looks like styrofoam in it! There was no customer support to call. I sent an email and no response. I am mailing it back with hope you will do the right thing and credit my credit card. Otherwise I feel I was scammed. UPDATE 12/17/2025 After writing an email to Peptidic, a very professional customer service representative sent me a long entailed email. She gave me a couple of options and I really felt like she wanted to rectify my situation. What I did not understand is the “styrofoam looking stuff” was indeed what I ordered. It just needed to be mixed/activated along with some other instructions I neglected to realize. I just wanted to be clear, that though I was unaware of those procedures when I purchased, Mary T. in Customer Support went above and beyond reaching out to me. Thank you for that!
