The peptides came and it looked good. And then the rubber seal was popped partially off. Affecting the sterility of the petide with peptide oozing out the top. Definitely don’t recommend, go with a new company

Outstanding quality and rapid delivery

The quality surpassed anything else I've tried, and it arrived incredibly fast in just 2 days. Its effectiveness was much better than other options I've used. I'm astonished it wasn't priced higher. This will definitely be my preferred choice going forward.

A leader in the industry...

A leader in the industry, they truly met my expectations. Shipping was quick, packaging was excellent, and the transparency with COAs available on the site was impressive. It's hard to find better service. I won't be ordering from anywhere else.

My go-to source from now on

Given that this is one of the most reputable companies in the field, I was thrilled with how quickly my package arrived. The packaging was fantastic, and having direct access to all COAs on the website really clinched it for me. I won't be looking elsewhere.

Promising company so far

Promising company so far; the peptides seem to be effective. I'll need to see how it goes from here.

Exceptional quality for the price

The quality surpassed any other provider I've used, shipping was lightning fast at just 2 days, and the effectiveness was clearly superior to other sources I've tried. I'm surprised it wasn't priced higher. This will be my top choice from now on.

Disappointing experience

This feels like a scam; my order never arrived and customer support is unreachable.

Lack of response from the company

The company truly does not respond. I had to dispute my charge because the vial I ordered arrived cracked. I reached out for a replacement but haven't received any reply in the past 3 days.

Concerns about batch testing

On my first order, I received 3 vials of glp-r. They promised two-day shipping, but it took 4-5 days due to the holidays. Everything arrived intact. My only concern is that most peptide vials include a QR code for third-party testing, but this one didn't have it; the results on the website might be for other batches. I thought about switching providers due to this, but since it's my second week injecting and I've had no issues, I plan to continue buying.

Contamination concerns

I ordered Ghk-cu, which looked fine initially, but after reconstituting, particles appeared within an hour and persisted for two days. Despite following clean techniques with bac water and alcohol swabs, it seems the vial was contaminated. They have not issued a refund or reached out. Very disappointing experience. Avoid this company.
