By your 40s, growth hormone drops by half, cellular repair slows, and inflammation becomes chronic. The BPC-157 + TB-500 + CJC-1295 + Ipamorelin stack restores the recovery machinery that made healing automatic in your 20s and 30s but no longer functions adequately.

Recovery involves tissue repair, inflammation management, growth hormone optimization, and cellular regeneration working simultaneously. Single peptides address one mechanism. The BPC-157 + TB-500 + CJC-1295 + Ipamorelin stack addresses everything for complete restoration.

Oral NAD+ precursors face digestive degradation, liver metabolism, and cellular uptake limitations. Direct subcutaneous administration bypasses every barrier, delivering concentrated NAD+ directly to tissues for efficient cellular absorption that oral supplements cannot achieve.

By age 50, NAD+ levels plummet to half of what they were at 20—creating chronic fatigue, brain fog, and poor recovery. This master molecule powers over 400 enzymatic reactions. Direct subcutaneous administration bypasses oral bioavailability limitations for optimal cellular restoration.

Retatrutide serves people with serious goals—20+ kilos, complete transformation, stubborn deposits resisting everything else. Triple-action GLP-1, GIP, and glucagon activation addresses every major fat loss pathway simultaneously for maximum results.

Your Saturday morning peptide primer. GHRP-2 - the potent growth hormone secretagogue creating strong, immediate GH pulses through ghrelin receptors. Everything you need to know about powerful, controllable growth hormone elevation and recovery enhancement.

Not everyone wants appetite suppression. SLU-PP-332 offers metabolic support instead—targeting fat utilisation and cellular energy production without altering hunger signals. For people who prefer supporting natural metabolism over manipulating appetite.

Your Saturday morning peptide primer. AOD-9604 - the modified growth hormone fragment isolating fat-burning properties without affecting blood sugar or tissue growth. Everything you need to know about targeted fat mobilisation through isolated GH lipolysis.

SLU-PP-332 is once-daily metabolic support for people who prefer simplicity over drama. No appetite suppression, no stimulants, no injections. It targets fat utilisation and cellular energy production—background support that fits seamlessly into morning routines.

Your Saturday morning peptide primer. PT-141 (Bremelanotide) - the melanocortin receptor agonist that enhances sexual desire through direct brain action. Everything you need to know about genuine arousal enhancement that works for both men and women.

Stubborn belly fat that persists despite overall weight loss is typically visceral fat - biologically different from subcutaneous fat and resistant to traditional approaches. Tesamorelin targets visceral fat through growth hormone, achieving 15-20% reduction.

Your Saturday morning peptide primer. Tesamorelin - the GHRH analogue specifically targeting visceral abdominal fat through sustained growth hormone elevation. Everything you need to know about preferential belly fat mobilisation and metabolic health improvement.

Stubborn fat deposits have different biology - higher alpha-receptor density, lower blood flow, enhanced insulin sensitivity. They resist approaches that work elsewhere. Retatrutide's glucagon pathway directly mobilises resistant deposits that dual-action compounds leave behind.

Your Saturday morning peptide primer. Sermorelin - the GHRH analogue that stimulates natural growth hormone production in brief, intense pulses. Everything you need to know about restoring youthful growth hormone patterns through enhanced natural production.

The last 10-20kg are harder to lose because your body deploys metabolic defense mechanisms - slowed metabolism, increased hunger hormones, enhanced fat storage. Tirzepatide's dual-action mechanism addresses the hormonal dysfunction that creates stubborn plateaus.

Your Saturday morning peptide primer. Retatrutide - the next-generation triple-action compound activating GLP-1, GIP, and glucagon receptors. Early clinical data shows 20-25% average weight loss. Everything you need to know about the cutting edge of fat loss.

Tirzepatide has overtaken every competitor to become the world's highest-selling weight loss compound in under two years. Clinical trials show 15-20% average weight loss versus 10-15% with single-action alternatives. Here's the science behind the explosive demand.

Your Saturday morning peptide primer. Tirzepatide - the dual-action compound that overtook single-action alternatives as the highest-performing weight loss medication. Clinical trials show 15-20% average weight loss versus 10-15%. Here's why it wins.

Old injuries often heal "good enough" but not properly, leaving poor-quality scar tissue and structural weaknesses. BPC-157 + TB-500 promotes comprehensive tissue remodelling, breaking down poorly organised tissue whilst building functional replacements.

Your Saturday morning peptide primer. Ipamorelin - the selective growth hormone secretagogue that creates targeted pulses without affecting other hormones. Everything you need to know about precise recovery enhancement and body composition improvement.
