Fast shipping great products!
One of the bottles was open,I need a refund
Great price but directions or syringes were not included. I’m a 1st time customer but have used GLP1 in the past and had some supplies left. Other than that, great experience thus far and I’m planning to reorder in the future. Thank you
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
