The longevity.

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide of 15 amino acids — sequence GEPPPGKPADDAGLV — derived from a protective protein sequence found in human gastric juice.

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on the natural peptide epithalamin, which is produced by the pineal gland.

GHRP-2 (Pralmorelin) is a synthetic hexapeptide ghrelin receptor agonist and potent growth hormone secretagogue.

MK-677 (ibutamoren, ibutamoren mesylate; development code MK-0677; also designated L-163,191) is a non-peptide, orally bioavailable spiroindoline compound that acts as a potent, selective, and long-acting ghrelin receptor agonist.

Abaloparatide is a 34-amino acid synthetic analog of parathyroid hormone-related protein (PTHrP) approved by the FDA under the brand name Tymlos for treating osteoporosis in postmenopausal women and men at high fracture risk.

Carnosine is a naturally occurring dipeptide (beta-alanine + L-histidine) found in high concentrations in skeletal muscle and brain tissue — long-lived, high-energy-demand tissues.

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates pituitary somatotrophs to secrete growth hormone.

GHK (Glycyl-L-histidyl-L-lysine) is a naturally occurring human tripeptide found in plasma, saliva, and urine.

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine.

Glutathione (GSH) is the body's most abundant endogenous antioxidant tripeptide, composed of glycine, cysteine, and glutamate.

Humanin is a 24-amino acid mitochondrial-derived peptide (MDP) encoded within the 16S ribosomal RNA gene of the mitochondrial genome.

Ipamorelin is a selective growth hormone secretagogue that stimulates the pituitary gland to release growth hormone (GH).

Mod GRF 1-29 (Modified Growth Hormone Releasing Factor 1-29) is a stabilized synthetic analog of endogenous GHRH with four amino acid substitutions that resist enzymatic degradation.

MOTS-c is a mitochondrial-derived peptide (MDP) encoded within the 12S rRNA gene of mitochondrial DNA.

Sermorelin is the shortest fully functional fragment of growth hormone-releasing hormone (GHRH), consisting of the first 29 amino acids.

Teriparatide is a recombinant form of the first 34 amino acids of human parathyroid hormone (PTH 1-34) and the first anabolic osteoporosis treatment approved by the FDA.

Thymosin Alpha-1 (Tα1) is a 28-amino-acid peptide originally isolated from thymic tissue and now produced synthetically.

Collagen peptides are short-chain amino acid sequences derived from enzymatic hydrolysis of native collagen (types I, II, and III).

Follistatin-344 is the 344-amino acid isoform of follistatin, a naturally occurring glycoprotein that potently inhibits myostatin and activin A — two TGF-β superfamily members that limit muscle growth.

FOXO4-DRI is a synthetic D-amino acid retro-inverso peptide designed to selectively eliminate senescent cells — aged, dysfunctional cells that accumulate with age and drive chronic inflammation.
