Sermorelin and TRT for Men Over 50: How the Combination Works, Benefits, and Safety

Sermorelin and testosterone replacement therapy (TRT) are sometimes prescribed together for men over 50 because they work through different, complementary pathways – TRT restores testosterone toward a healthy range, while sermorelin nudges the body’s own pituitary gland to release more growth hormone. Both testosterone and growth hormone tend to decline with age, so some clinicians […]

Sermorelin for Women: Benefits, Dosage, and What to Expect in Perimenopause & Menopause

Sermorelin is a prescription growth hormone-releasing peptide that some women use, under a clinician’s supervision, to support energy, sleep quality, body composition, and skin as their natural growth hormone declines with age — including during the perimenopause and menopause transition. It works by signaling the pituitary gland to release the body’s own growth hormone (GH) […]

NAD+ IV Therapy for Addiction Recovery: How It Works, Protocol & Evidence

NAD+ IV therapy for addiction is used by some recovery and detox clinics as a complementary, supportive option during early recovery, with the goal of helping with low energy, cravings, and post-acute withdrawal symptoms (PAWS). It is not a standalone treatment, not a cure, and not FDA-approved for substance use disorder (SUD) or withdrawal. The […]

How to Increase NAD+ Naturally: Food, Fasting, Exercise & Sleep

You can support NAD+ naturally by exercising (especially high-intensity interval training), practicing intermittent fasting or caloric restriction, eating foods rich in niacin and tryptophan, prioritizing quality sleep, using heat exposure like sauna, and limiting alcohol, overeating, and excess UV exposure. These habits stimulate the enzymes that recycle and rebuild NAD+, and they can meaningfully slow […]

Does NAD+ Actually Work? What the Human Studies Really Show (2026)

Short answer: it depends on what you mean by “work.” If the question is whether NAD+ therapy and precursors like NMN and NR actually raise the NAD+ levels in your body, the answer is a clear yes — that part is well established in human trials. If the question is whether raising your NAD+ delivers […]

NAD+ Side Effects & Safety: What to Know Before You Start (IV, Injection & Oral)

NAD+ is generally well tolerated, and most side effects are mild, temporary, and tied to how fast or how much you take rather than the molecule itself. Across all three delivery routes — intravenous (IV) infusion, subcutaneous or intramuscular injection, and oral NMN/NR supplements — the most commonly reported effects are flushing or a warm […]

NAD+ vs NMN vs NR: Which NAD Booster Is Right for You? (2026 Evidence)

Short answer: NAD+ is the destination, and NMN and NR are two routes to get there. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme your cells use for energy and repair, but you can’t efficiently absorb the whole molecule as an oral pill. So most supplements use a precursor the body converts into NAD+. The two […]

To get sermorelin online safely, you need a valid prescription from a licensed US clinician.

Sermorelin Side Effects & Safety: Risks, What’s Common, and When to Call Your Provider

Sermorelin is generally well tolerated. The most commonly reported side effects are mild and short-lived: redness, itching, or swelling at the injection site, flushing or a feeling of warmth, headache, and occasional dizziness or nausea. Serious reactions are rare. Because sermorelin works by prompting your own body to release growth hormone in its natural pulsatile […]

Sermorelin Dosage & Injection Protocol: How Much, When, and How to Inject

If you have been prescribed sermorelin, the typical dose your clinician sets falls in the range of roughly 200 to 500 mcg, given as a small subcutaneous injection once nightly before bed on an empty stomach, often on a 5-days-on, 2-days-off schedule. Many providers start at the low end and titrate upward based on your […]

Sermorelin vs Ipamorelin, CJC-1295 & HGH: How the Growth Hormone Options Compare (2026)

If you’re weighing the major growth hormone options, here’s the answer first: sermorelin is the gentlest, most physiologic choice — it nudges your pituitary to release growth hormone in your body’s own natural rhythm. Ipamorelin works through a different receptor and is often stacked with CJC-1295 for a stronger, longer-lasting effect, making that combo the […]
