Forgive me for repeating this, but I am a fan of Blackmoor nursery, received an email from them advertising their goji berries with an enticing picture of a twig dripping with beautiful red berries, and emailed to ask them when their berries ripen, as I am fed up with my 2 bushes which are huge in spite of regular pruning, flowered a lot in early October, and are clearly NOT going to produce ripe berries. He wrote a helpful answer which I show below.
My son has a Thai/Chinese wife whose very lively and beautiful Chinese mother (in her 70s) eats dried goji berries as a matter of daily routine. Never fresh. They are a bit like raisins. I am very disappointed with my bushes, and am thinking of buying one from Blackmoors as a last attempt.
By the way, they grow incredibly easily from cuttings, survive drought, and I am sure I will never manage to dig them up. Here is the Blackmoor email again:

The Goji berry is a little new to me too but from my experience of growing the fruits (3 years now)
They flower here in Hampshire late Aug-early September. The image shown on the website and email was taken on Monday this week so from the early flowers they take around 6 weeks to form and ripen. As you say they are rather vigorous and I have several systems for growing them and the best seems to grow them upright with support and keep any side growth trimmed several times during the growing year.
