I'm throwing in my 2 pence worth here. Epitalon/epithalon are the same thing epithalon is a name registered by khavinson. So the Chinese companies use the name epitalon.
It's not very difficult to make as has been said its just 4 amino acids long. The reason it's expensive is that the stuff from Russia is sold there to a captive market (rich Russians) and he charges as high a price he can get.
It's not thrown together in a bathtub it like any other peptide and uses state of the art synthesis machinery to produce and its a niche product and sold in very small amounts hence the price. The amino acids are also produced in laboratory conditions heavy metals don't come into it . If it was used by body builders it would be a fraction of the price it is. It's supply and demand.
The main difference between the purification percentages is down to the washing after it is manufactured in the synthesizers. it's laid down by the machines on a plastizser rather like printing four dots with a special glue between each amino acid to hold them together. Then the next 4 and continues like dots all in a row with the amino acids in sequence and the glue binder missing between every forth short chain. And that's in the smaller cheaper machines. Afterwards it goes through a number of chemical washes and filtration to release each chain of four acids from the plastisizer to seperate them. the lower the percentage the less washes and filtration they have had. Hence the lower price. As there is much less time spent in the washing process. Plus some incomplete chains that have been broken in the process. How bad to a person these chemical washes are I don't know but I would think anything above 98 per cent would have minimal amounts left in.
The lower price quoted is probably nearer the true cost than the inflated price used by the group selling it in Russia.
Chimes prices for most peptides and hormones are about a tenth the cost of those in the west for many reasons.
HGH is not dangerous if taken in amounts below 2iu a day this amount brings it back to the level it was when we were in our late teens. The concern about HGH is that is causes the liver to produce more IGF 1 that has been postulated to increase the risk of cancer as it is an upregulator of telomerase which could trigger pre cancer cells to start increasing by lengthening their telomeres. But has not been proven in trails including examining thousands of kids here in the UK that have taken it as youngsters to enable them to attain their normal growth which they lack. Higher incidents of cancer were not found when compared to the normal kids the same age.
The hgh part peptides sold by many peptide suppliers mentioned ( sorry can't remember it's full name ) are a way of getting round the law especially in the US where it's illegal to sell HGH except on prescription from a doctor if you have certain health problems. they contain only part of the HGH sequence that is found in full HGH just a smaller number than the full 191 amino acids that are in HGH. They may be quite effective but I have no idea as I've never tried them.
