Diesel I lost my source and found 2 more and have received prompt delivery recently with what appears to be great product. I had switched over to gearedfast before they went down here and know the product was legit based on sides. Following that I was happy enough with the product and the quality that I found 2 different sellers of the exact same product. It is kigtropin....the product I just received from the 2 new sources, ordered from both, came in 5 days from China. VERY low price and I will describe the quality in terms of appearance and all the little details that add up to legit....The product came in original kig boxes with kig sticker and pharma papers. Little things I look for were all present...The bottles were all well labeled with batch and expiration dates and professionally done. For me the main thing I saw was that each bottle is filled half way perfectly with no difference at all. The growth was all a solid cylinder in exact size and is hard with a little tit on the top of the growth indicating it was professionally filled. When mixing with bac water it does not all instantly mix together such as peptides do which is a good sign of 191. It mixes exactly like true gensci jintropin. Either its g2g or someone went to a hell of a lot of trouble to fake it....Nice full bottles though and a great deal of the fakes are real 191 they are just low mg or underfilled, fakes will also be inconsistent in many ways...these are perfect in every aspect. I began using the new order about a week ago and I can report my sides have continued. I was already using G so there has not been enough time to give a solid review on the product as of yet but everything just feels right with it and especially considering I was already using this product from the past by a different seller knowing it is legit and this is identical in every way. The bottles have the "kigtropin" tops, I know that means a lot to some. The price will probably go way up on this product eventually as the brand catches hold, but as for now it is the cheapest you will find. I did hit a larger dose than I normally use and did get the G rush as well. Again, service from the seller is incredible. Very good quick email responses before and after the sell, tracker within 12 hours and in the box in 5 days! I continue to have contact with the seller building the trust factor and will order again before the week is out. I will pm the info as I dont want to leave it in open forum in case it violates the policy here. 3.7 milligram by the way!
