Super quick delivery from one coast to the other. Product seems to be very high quality. Only thing I’d like to see if large vials with the larger volume peptides- like Reta 60 should come in a large container.
Ordered 2x and the same fast delivery.

Consistent Excellence — Unmatched Quality and Service
They truly underpromise and overperform. In a market where many companies make big claims, Instant Peptides consistently delivers results that exceed expectations. Their pricing is among the best you’ll find anywhere — not just competitive, but genuinely fair for the level of quality they provide. What stands out most is that their product purity and consistency are right on par with, if not better than, many of the top-selling peptide suppliers in the industry.
Their customer service deserves special mention. Responses come through faster than expected — often within hours — and they’re always professional, clear, and helpful. That kind of reliability builds trust, especially in a field where communication and quality assurance are crucial.
Overall, this company sets a standard for how an online supplier should operate: transparent, dependable, and performance-driven. It’s refreshing to see a business that prioritizes its customers’ confidence and satisfaction as much as it does the products themselves.

Too long for shipping
I live two hours away from where the product was shipped in florida, and instead of receiving the package in two days as they stated as they do two day shipping, I received my order on day 5.

Reply from Instant Peptides
Hannah, thank you for your feedback. Your order was placed Wednesday evening and shipped out Thursday morning using FedEx 2-Day service. Since FedEx does not deliver 2-Day packages over the weekend, your package was delivered on Monday, which was the next available business day. The timing simply fell across the weekend, which was out of our control.
Our shipping policy is that products should deliver in two business days provided that the order is placed before the FedEx cutoff window. Please reach out to us directly at support@instantpeptides.com and we will make sure your next order arrives with an expedited shipping option at no extra cost.
Thank you for your patience and your support.

Easy ordering, fast shipping, undecided product efficacy
Easy website navigation and checkout. Using Apple Pay made process effortless. They advertised quick shipping and didn’t disappoint. 4 business days from order to delivery.
I have been on 2mg weekly of Retatrutide for 6 months now. My old vendor had availability issues and was more expensive. Swapping to instant peptides seemed like a win win. I’ve performed 2 shots so far and have noticed an increase in my hunger and a dissipation of my Reta tingle. Possibly coincidence but I am having doubts as to this products validity. Will give it another 2 weeks and reassess if I need to swap back to old vendor.

Reached out to instant peptides. They are sending me a new Reta from another batch. Excellent customer service so far.
