HGH Fragment 176-191 5mg

Description

Fragment 176-191 5mg from Blue Sky Peptide is 5mg of HGH Fragment 176-191 in a sealed glass vial. HGH Fragment 176-191 is a C-terminal fragment of human growth hormone. This batch tested at 99.56% purity. It’s sold for laboratory research only.

About HGH Fragment 176-191

HGH Fragment 176-191 is the last 16 amino acids of human growth hormone, with the disulfide bond from the parent protein. It’s the region of GH linked to fat breakdown, without the parts that bind the GH receptor and drive growth.

AOD-9604, which we also sell, is the same fragment with one extra tyrosine on the front.

HGH Fragment 176-191 mechanism of action

Full growth hormone does two separate jobs: growth, through the GH receptor and IGF-1, and fat metabolism. The fat effect seems to sit in the C-terminal end of the molecule.

In animal fat tissue, the fragment raised lipolysis, the breakdown of stored fat, and lowered lipogenesis, the building of new fat. It does this without binding the GH receptor, which is why it’s useful for separating GH’s metabolic effects from its growth effects.

HGH Fragment 176-191 research

Monash University researchers, including Ng and colleagues in 2000, reported that the fragment cut weight gain and body fat in obese mice and increased fat breakdown in fat tissue.

Those studies also found it didn’t raise IGF-1 or affect blood sugar the way full GH does. Human data come mostly from the AOD-9604 trials, which didn’t reach their weight loss targets.

HGH Fragment 176-191 compared with similar compounds

Here’s how Fragment 176-191 5mg fits among related compounds. HGH Fragment 176-191 is the 16-residue C-terminal end of growth hormone, the parent of AOD-9604. By comparison:

• AOD-9604 is hGH fragment 177-191 with an extra tyrosine, studied for fat breakdown without raising IGF-1
• 5-Amino-1MQ is a small molecule that blocks the enzyme NNMT inside fat cells
• MOTS-c is a 16-amino-acid peptide coded in mitochondrial DNA, studied for glucose use in muscle

These four are studied for fat metabolism but act in very different places: the growth hormone fragments on fat tissue from outside, 5-Amino-1MQ and MOTS-c from inside the cell. See them all on our weight loss peptides page.

Lab-tested Fragment 176-191 5mg

The current batch of Fragment 176-191 5mg tested at 99.56% purity by mass spectrometry and UV (HPLC) analysis. That figure comes from the batch report, not a marketing estimate, and it’s the reason we list the exact number instead of rounding up.

Every vial is labeled with the compound, the amount and the batch. If your lab keeps paperwork on file, email us the batch number from the label and we’ll send the certificate of analysis for it.

If a result looks off, check the batch number first, then your handling notes. Most problems with HGH Fragment 176-191 come from storage or mixing, not the material.

Fragment 176-191 5mg reconstitution and concentration

Concentration is the amount in the vial divided by the liquid you add. With 5mg in this vial:

• 1mL of water gives 5mg/mL
• 2mL of water gives 2.5mg/mL
• 3mL of water gives 1.67mg/mL

Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.

Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake it.

Fragment 176-191 5mg storage and shelf life

Store sealed vials of Fragment 176-191 5mg in the freezer (-20°C) or the fridge (2 to 8°C), out of direct light. Mixed solution goes back in the fridge and should be used within about 28 days.

A 10-slot vial case keeps open and sealed vials upright and apart, which makes the fridge shelf a lot easier to manage. For transport, the Blue Sky hard storage box is the sturdier option.
