Great service

Service Rating: Price, quality and delivery are generally good. However, they are often 'Out of Stock' for long periods on some items which requires my sourcing from elsewhere ... not good for them as I prefer to order everything from one place!
Product: Very effective ... but I need it with the same dosage in L-Carnitine 1000mg which is too often 'Out of Stock'. They do have L-Carnitine 500mg but this works out at twice the price... so leads me to source elsewhere!

Service Rating: Fast delivery, great prices.
Product: L-theanine is subtle but very effective. I have found that it's great for a) a calm focus, b) reducing stress and c) helping you achieve a deep long sleep without any drowsiness in the morning.

Service Rating: The website is user friendly, the ordering process simple, the information on the products is good. Delivery was quick, packaging good.

Been on the pills now for a couple of weeks but have noticed no discernible change which is a little disappointing
Product: Taking this with Pycnogenol which combined is reportedly a cure or helps alleviates symptoms of Erectile Dysfunction. Been taking for two weeks with no discernible difference. So very disappointed at this stage but will complete the 90 day programme

Service Rating: Quick delivery good website cheap prices.
Product: Why three stars because the vitamens placed in plastic bag instead of can or box so when i picked it from my mail box it was very warm.

Service Rating: I love just vitamins, they are a good price and quick delivery, and my favorite bit is they are in a seal pack so can be posted. I've used them 3 times so far and will continue to.
Product: I love the collagen tablets, they make my skin soft and wrinkle free, I take 2 a day so the 90 tablet pack lasts a good while.
