Only accepts checking acct payments

Products and cs are good from my previous orders, but now they only offer payment using a checking account and that method of payment offers zero protection so I had to go with another supplier for my last 2 orders

Got bad peptide

Got bad peptide! Sent an initial email regarding shipping and they responded asap. Once we received and tested within a week. The peptide was not good. Sent them another email and got ghosted!

I have ordered from them for…

I have ordered from them for approximately 8 months. They have been good to respond to emails and I have received all my orders.
The extreme issue now is their payment method!! I recently tried to order using my regular Mastercard but it was always declined (for NO REASON). So I borrowed my friend’s Visa and the order went through. I’m looking for another company to order from.

Doesn't stand up to mistakes

RpL shorted me a bottle on my shipment, then don't reply to emails. sadly I can't do business with a flighty company like this. reminds me of a company in liquidation pawning off the last of their stock, at that point customer service is the last thing you care about

Customer service has been prompt

Customer service has been prompt, products great thus far. Been using for test subjects a couple of months now, products legit. One day sale today. They get my vote

Good source

One of the B waters had opened on me after I put a decent amount of air in there and they sent me another one, plus one. Customer service was nice, product is good, shipping is fast.

I haven’t much experience with other companies. I have gotten the Gw 501516, and mk 2866

I do notice a good amount of energy in my Rat and when going hard there’s most definitely an increase in stamina, recovery which inevitably after intense workouts my rat can feel the immediate swolness. All & all my Rat feels younger, healthier and zero noticeable side effects. Maybe should be watered better!😐

I’m a Returning Customer for a reason

I’m a Returning Customer for a reason: Great products, reasonable pricing and a customer service oriented company! I had a minor issue and they immediately resolved and that is the best sign of a good company! Thank you RPL.
