HGH Fragment 176-191

Primary target

Nicotinamide N-methyltransferase (NNMT)Neelakantan 2018

Beta-3 adrenergic receptors on adipocytesHeffernan 2001

Pathway

NNMT inhibition → preserved cellular SAM + NAD⁺ → restored methylation balance + ↑ thermogenic gene expressionNeelakantan 2018

Fragment → β3-AR upregulation → Enhanced lipolytic sensitivityHeffernan 2001

Downstream effect

Reversal of HFD-induced obesity in murine models; improved metabolic profileNeelakantan 2018

Increased lipolysis and beta-3 AR mRNA expression without IGF-1 axis activation

05Administration Protocol

Parameter

5-Amino-1MQ

HGH Fragment 176-191

1. Form

Oral capsule. No injection.

Subcutaneous injection primary route in research context. Oral administration demonstrated efficacy in animal models at 500 mcg/kg.

2. Administration

Take with water, fasted preferred.

Once daily dosing used in animal studies. Timing not specified; GH-independent mechanism suggests flexibility.

3. Timing

Morning fasted.

Animal protocols: 14–19 days. Human duration not established — no published trials.

4. Storage

Room temp ≤25 °C, dry place.

Lyophilized peptide storage per standard peptide protocols. Metabolite stability suggests refrigerated reconstituted solution viable.

5. Caveat

Monitor B-vitamin status with chronic use.

Detectable in urine via SPE-LC-MS at 50 pg/mL LOD. Extended detection window via stable metabolite CRSVEGSCG.Cox 2015
