| Hi, I need some 10 mM HCl to reconstitute IGF-I and was wondering if it is something that can be purchased or does it have to be made, and what procedure and other compounds I would need in order to make? BTW - Here is a list of the different types of HCl available to me, is it possible that any of them could be used in place of 10 mM HCl Hydrochloric Acid Hydrochloric Acid Concentrate Hydrochloric Acid Concentrate, 1N Hydrochloric Acid R1 (250 g/L HCl) Hydrochloric Acid Solution Hydrochloric Acid, 0.0100 Normal (N/100) Hydrochloric Acid, 0.0200 Normal (N/50) Hydrochloric Acid, 0.0500 Normal (N/20) Hydrochloric Acid, 0.05882 Normal (N/17) Hydrochloric Acid, 0.100 Normal (N/10) Hydrochloric Acid, 0.100 Normal (N/10) in Isopropyl Alcohol Hydrochloric Acid, 0.1142 Normal, for Kjeldahl Analysis of Proteins Hydrochloric Acid, 0.1782 Normal, 1 mL = 5 mg CaO (Lime) Hydrochloric Acid, 0.200 Normal (N/5) Hydrochloric Acid, 0.200 Normal (N/5) in Isopropyl Alcohol Hydrochloric Acid, 0.250 Normal (N/4) Hydrochloric Acid, 0.250 Normal (N/4) in Isopropyl Alcohol Hydrochloric Acid, 0.300 Normal Hydrochloric Acid, 0.500 Normal (N/2) Hydrochloric Acid, 0.500 Normal (N/2) in Isopropyl Alcohol Hydrochloric Acid, 0.600 Normal Hydrochloric Acid, 1% (v/v) Aqueous Solution (1 + 99) Hydrochloric Acid, 1.00 Normal Hydrochloric Acid, 1.5% (v/v) Aqueous Solution Hydrochloric Acid, 1.96% (v/v) Aqueous Solution (1 + 50) Hydrochloric Acid, 10% (v/v) Aqueous Solution (1 + 9) Hydrochloric Acid, 10.0 Normal Hydrochloric Acid, 2% (v/v) Aqueous Solution (1 + 49) Hydrochloric Acid, 2.00 Normal Hydrochloric Acid, 2.50 Normal Hydrochloric Acid, 20% (v/v) Aqueous Solution (1 + 4) Hydrochloric Acid, 25% (v/v) Aqueous Solution (1 + 3) Hydrochloric Acid, 25% v/v (1+3) Hydrochloric Acid, 25% v/v (1+3) Hydrochloric Acid, 3.00 Normal Hydrochloric Acid, 5% (v/v) Aqueous Solution (1 + 19) Hydrochloric Acid, 5.00 Normal Hydrochloric Acid, 50% (v/v) Aqueous Solution (1 + 1) Hydrochloric Acid, 6.00 Normal Hydrochloric Acid, 6.00 Normal, Packaged in Glass Hydrochloric Acid, 6.25 Normal Hydrochloric Acid, 75% (v/v) Aqueous Solution (3 + 1) Hydrochloric Acid, 8.33% (v/v) Aqueous Solution (1 + 11) Hydrochloric Acid, Dilute R (73 g/L HCl) Thank you, David Low |

But why would you want to formulate your own drugs, when safely formulated products are already on the market? And why would you want to take this one in particular, which is the subject of so many bogus marketing claims? [Only registered users see links. ] Furthermore, HCl is a rather dangerous acid. Imagine if you do not dilute it to the correct concentration, then injest it, inhale it, or inject it. You might die. Someone you know might die. Or you might go to prison. Don't do it. Dave |

What safely formulated drugs are you aware of that can mimic the effects of IGF-I? The article you referenced relates to r-hGH and not IGF-I. If I was to use HCl acid, I may well injure myself if I am stupid, but I think that death is not likely. If 10 mM HCl does not harm cell cultures, why would it injure me? I am confused how my actions could kill someone I know or land me in jail? I am not working with a scheduled or listed substance, nor am I planning to do anything illegal. Thanks, David |

IGF-1 itself is available as a dietary supplement, from many of the same supplement companies which sell HGH supplements. And while I am skeptical of the supplement industry in general (since the industry is almost completely unregulated) they do, sometimes, hire experienced chemists to safely formulate their products. My concern, when I read your message, is that you don't sound like an experienced chemist. Therefore, it would be particularly unsafe for you to mix chemicals which you plan to later put in your body, or sell to another person to put in theirs. The article I posted is indeed about HGH, rather than IGF 1 specifically, however the two hormones are physiologically related. HGH exerts its effect by stimulating the production of IGF 1 in the liver. Several of the bogus claims which were earlier being made regarding HGH are now being made regarding IGF 1. They are still bogus. IGF 1 is a polypeptide, just like HGH, and neither of these will enter the blood stream if taken orally. If you are planning to take the stuff intravenously, then obviously, you must be even more cautious about mixing your own. My comment about the possibility that you might "go to jail" was related to an assumption I made that you planned to sell this stuff to others. If you were to sell it to another, and caused them injury, you could be held liable. Dave |

The company that patented and manufactures the specific IGF-I that I am interested in, specifically to promote growth in cell cultures, recommends that you reconstitute it with 10mM HCl before adding it to your cell cultures? As do their exclusive distribution partner in the USA. David. |

Dave, I certainly do not plan to sell anything, nor would I ever inject it intravenously. You are correct, I am not an experienced chemist, which is why I came here for some assistance. I am aware of the supplements that claim to increase hGH or IGF-I, but I also know them to be bogus, I though you were aware of a drug that would do so, perhaps one which I was not familiar with. Right now IGF-I is available on the 'black-market, in fact it has been for several years. Previously, it was regular IGF-I and came with a vial of 10mM HCl or 100mM acetic acid for reconstitution, presently all that is readily available is Long R3 IGF-I which comes already reconstituted in benzyl alcohol. Ignoring the debate on safety, potential side effects or whether it actually works or not, I do not believe that you can suspend a polypeptide like IGF-I in benzyl alcohol with degrading or killing it. I hope this explains my interest. Thanks, David. |

Concentrated HCl usually comes as 10M solution. What do you need this IGF-I (whatever it is good for?) anyways? MfG Chris |

The hydrochloric acid in your stomach is probaby stronger than (I did not bo9ther to look it up) than 10 mM. Impurities may be a bigger problem than the acid. Fully ionized and active, 10 mM should give a pH of 2. Bill |
