HGH Fragment 176-191, 5 mg. HGH Fragment 176-191 is the final sixteen amino acids of the growth hormone molecule, the section linked to fat breakdown, without the parts that bind the growth hormone receptor.

What is in this vial

It is the smaller of the HGH Fragment 176-191 vials sold here, which means less substance standing in solution at a time. The powder has no concentration of its own: it is set when you add the water. This vial with 2 ml of bacteriostatic water gives 2.5 mg per millilitre, and with twice that volume, half as much.

The conversion of an amount into insulin syringe units is worked through in the guide on syringe units, and the rules that change once the powder is dissolved are in storage.

Genheal as the manufacturer

Genheal covers the growth hormone axis more completely than the other two brands and is the only one here supplying the BPC-157 and TB-500 blend, tesamorelin and tirzepatide. Its vials carry a code under the hologram and a batch certificate, checked the same way as any other brand in this shop.

What the evidence says

In obese mice it reduced fat tissue by 12 to 23 percent. In the only published human trial there was no statistically significant difference in weight loss or body composition. The full account, with the sources and the limits, is on the HGH Fragment 176-191 page, and the background in the guide on HGH Fragment 176-191.

We publish no dosing schedules. Sold as research material, not as a medicine.

Genheal fills the fragment in 5 mg, the same as Bio-Peptide. Because the dissolved fragment degrades through deamidation and oxidation faster than most peptides here, the smaller vial is the more practical choice unless you have a reason to keep a larger solution.

Concentration in this vial

Water added Concentration Per unit on a U-100 syringe
1 ml 5 mg/ml 50 mcg
2 ml 2.5 mg/ml 25 mcg
5 ml 1 mg/ml 10 mcg

The table is arithmetic and nothing else: it converts the 5 mg in this vial into the concentration you get for a chosen volume of bacteriostatic water. It is not a dosing recommendation, and we publish none.

This vial next to the other HGH Fragment 176-191 vials

The same compound is sold here in two other versions: Bio-Peptide, 5 mg and Nouveaux Ltd., 10 mg. The molecule is identical in each; what differs is the manufacturer and the amount in the vial. This is the smallest of the 3, so less substance stands in solution at a time.

Also from Genheal in this group

Within Growth hormone peptides, Genheal also supplies CJC-1295 5 mg, CJC-1295 with DAC 5 mg and GHRP-2 10 mg.

Questions

How much HGH Fragment 176-191 is in this vial?

5 mg of lyophilised powder from Genheal, in one vial.

What concentration does 2 ml of water give?

2.5 mg per millilitre, which is 25 mcg per unit on a U-100 insulin syringe. Other volumes are in the table above.

Is this the same molecule as the Bio-Peptide vial?

Yes. HGH Fragment 176-191 is the same compound in every vial here, and both hold 5 mg. What differs is the manufacturer and the batch certificate that comes with it.

Verification and delivery

Every vial carries a code under the hologram and comes from a batch with a certificate of analysis; how to check both is described in check your product. We ship within Poland and abroad. Outside Poland the cost is quoted individually, depending on weight and destination country, and confirmed before dispatch: shipping and payments.
