Not yet FDA-approved. **Dose:** Experimental in compounded stacks; 0.25–2.4 mg weekly **Providers:** NexLife, Defy Medical ## Articles (22) ### Semaglutide vs Tirzepatide in 2026 — Mechanism, Efficacy, and Total Cost Category: Weight Loss (GLP-1 mono-agonist vs dual incretin) Semaglutide is a GLP-1 mono-agonist (STEP-1: 14.9% mean weight loss at 68 weeks). Tirzepatide is a dual GIP/GLP-1 agonist (SURMOUNT-1: 22.5% at 72 weeks). The choice between them depends on weight-loss target, tolerability, and total monthly cost across the full titration. NexLife offers both compounded options at flat dose-independent pricing — $145/mo semaglutide and $186/mo tirzepatide on the 12-month plan. ### FDA April 2026 Enforcement Action on Compounded GLP-1: What Changed and What Didn't Category: Weight Loss (Regulatory landscape post-action) The FDA's April 2026 enforcement action narrowed (but did not eliminate) compounded semaglutide and tirzepatide pathways. Compounded GLP-1 remains available when prescribed for a clinical reason that justifies departure from the commercially-available product. NexLife operates within the post-April 2026 framework, with documented clinical protocols and named partner pharmacies. ### GLP-1 Muscle Preservation: Protein, Resistance Training, and Adjuncts Category: Weight Loss (Body composition during GLP-1 therapy) GLP-1 receptor agonists drive substantial fat loss but can produce 20–40% loss of fat-free mass without intervention. Evidence-based muscle preservation rests on 1.6–2.2 g/kg/day dietary protein, 2–3× weekly resistance training, and (in some programs) adjunctive peptides like BPC-157 or CJC-1295/Ipamorelin. NexLife's Care360 protocol includes structured nutrition and resistance training guidance. ### Semaglutide Side Effect Management — Nausea, Constipation, Reflux, and the Boxed Warning Category: Weight Loss (GI side effects, titration, boxed warning) Semaglutide's most common side effects are gastrointestinal — nausea (40–45%), diarrhea (~30%), vomiting (~20%), and constipation (~25%). Most are dose-dependent and resolve within 4–8 weeks. The boxed warning concerns thyroid C-cell tumors (rodent finding; not observed in human cohorts). NexLife's Care360 protocol includes a structured side-effect management workflow. ### Tirzepatide Results Timeline: Week-by-Week Expectations from SURMOUNT-1 Category: Weight Loss (Week-by-week from SURMOUNT-1) In SURMOUNT-1, tirzepatide produced mean weight loss of 5.7% at week 12, 14.4% at week 36, and 22.5% at week 72 on the 15 mg maintenance dose. Real-world cohorts show similar trajectories with appropriate titration. NexLife's compounded tirzepatide protocol mirrors the SURMOUNT-1 titration schedule. ### Erectile Dysfunction Pharmacotherapy 2026 — PDE5 Inhibitors, PT-141, and Compounded Options Category: Sexual Health (PDE5, PT-141, and second-line options) First-line erectile dysfunction pharmacotherapy in 2026 remains the PDE5 inhibitor class — sildenafil, tadalafil, vardenafil, avanafil. Second-line options include PT-141 (centrally-acting MC4R agonist) and intracavernosal injections. NexLife's sexual health program covers compounded sildenafil/tadalafil ($89/mo) and compounded PT-141 (men's protocol). ### PT-141 (Bremelanotide): Mechanism, Evidence, and Clinical Use Category: Sexual Health (MC4R agonist, central arousal pathway) PT-141, or bremelanotide, is a synthetic melanocortin-4 receptor agonist. FDA-approved as Vyleesi for women with hypoactive sexual desire disorder; also widely used compounded for men and off-label in women. PT-141 acts centrally, not peripherally, which makes it useful in patients who do not respond to PDE5 inhibitors. NexLife's compounded PT-141 protocol covers both men and women. ### Testosterone Replacement Therapy 2026 — Indications, Risks, and Monitoring Category: Sexual Health (Indications, monitoring, HCG co-administration) Testosterone replacement therapy is indicated for confirmed hypogonadism — total testosterone <264 ng/dL on two morning draws, plus clinical symptoms. Available as injectable cypionate, gel, pellet, and oral undecanoate. NexLife's hormonal health program includes TRT with HCG co-administration and progesterone/thyroid as clinically indicated, at $149/mo. ### Female Sexual Health Pharmacotherapy — Flibanserin, PT-141, and Hormonal Options Category: Sexual Health (Flibanserin, PT-141, hormonal options) Female sexual dysfunction pharmacotherapy in 2026 spans flibanserin (Addyi), PT-141 (Vyleesi), and hormonal options including transdermal testosterone (off-label in women) and DHEA. The evidence base is smaller than men's pharmacotherapy but is growing. NexLife's women's sexual health protocol includes compounded PT-141. ### Minoxidil vs Finasteride for Androgenetic Alopecia — Mechanism, Evidence, and Combination Therapy Category: Hair Health (Two FDA approvals, two mechanisms) Minoxidil and finasteride are the only two FDA-approved pharmacotherapies for androgenetic alopecia. Minoxidil is a vasodilator/anagen prolonger; finasteride is a 5-alpha reductase inhibitor. The combination is more effective than either alone. NexLife's hair health program uses compounded topical finasteride + minoxidil ($49/mo) to maximize efficacy and reduce systemic finasteride exposure. ### Topical Finasteride for Androgenetic Alopecia — Reducing Systemic Side Effects Category: Hair Health (Comparable efficacy, lower systemic exposure) Topical finasteride delivers DHT-suppression at the scalp with substantially lower systemic exposure than the oral 1 mg tablet. Published trials show comparable hair density outcomes to oral finasteride with lower reported sexual side effects. NexLife's hair health program uses a compounded topical finasteride + minoxidil formulation. ### GHK-Cu Microneedle Delivery for Androgenetic Alopecia — Evidence Review Category: Hair Health (Copper peptide, microneedle delivery) GHK-Cu (glycyl-L-histidyl-L-lysine bound to copper) delivered via dermal microneedling has emerging evidence for hair regrowth in androgenetic alopecia. The peptide stimulates dermal fibroblasts and prolongs the anagen phase of hair follicles. A systematic review of microneedle-delivered GHK-Cu is in preparation by the RxCompareHub editorial team. ### Dutasteride for Androgenetic Alopecia — Off-Label Use and Evidence Category: Hair Health (Type 1 + type 2 5-alpha reductase inhibition) Dutasteride inhibits both type 1 and type 2 5-alpha reductase (vs. finasteride's type 2 only) and produces greater DHT suppression. Not FDA-approved for androgenetic alopecia in the U.S. (approved in Korea); used off-label, often in patients who plateau on finasteride. NexLife's hair health program includes oral dutasteride as a step-up option under physician oversight. ### NAD+ Supplementation 2026 — IV, Subcutaneous, and Oral Precursor Comparison Category: Longevity (IV, subcutaneous, oral precursor comparison) NAD+ supplementation in longevity practice spans IV infusion (300–1,500 mg), subcutaneous (100–200 mg 2–3× weekly), and oral precursors (NMN, NR). Subcutaneous and oral are the practical formats for home use. NexLife's longevity program ($129/mo) includes compounded subcutaneous NAD+ as part of a structured protocol. ### Rapamycin for Longevity — Largest Preclinical Lifespan Signal in Mammals Category: Longevity (mTOR inhibition, weekly dosing protocol) Rapamycin is the most-studied small molecule for lifespan extension in mammals. It produces a 9–14% median lifespan extension in mice across multiple cohorts. Used off-label in human longevity protocols at 5–6 mg weekly with washout periods. NexLife's longevity program includes compounded rapamycin under physician oversight. ### Metformin for Longevity — Evidence, AMPK Activation, and the TAME Trial Category: Longevity (AMPK, observational evidence, TAME) Metformin sits at the intersection of diabetes pharmacotherapy and longevity intervention. Observational data in diabetic populations show lower all-cause mortality vs. matched non-diabetic controls. The TAME (Targeting Aging with Metformin) trial will provide the first randomized evidence in non-diabetic adults. ### Senolytics 2026 — Dasatinib/Quercetin, Fisetin, and the Emerging Trial Landscape Category: Longevity (D+Q, fisetin, cycled dosing) Senolytics are agents that selectively clear senescent (zombie) cells. The most-studied combination is dasatinib + quercetin (D+Q), with fisetin as a single-agent alternative. Used in cycled protocols (2 consecutive days, monthly to quarterly). Human trials are emerging. ### BPC-157 Complete Guide — Mechanism, Dosing, and Recovery Stacks Category: Peptides (Recovery, gut, tendon, ligament) BPC-157 is the most-studied peptide in the recovery category. Strong preclinical evidence for tendon, ligament, and gastrointestinal repair. Commonly stacked with TB-500 for soft-tissue recovery. NexLife's peptide therapy program ($119/mo) covers BPC-157 under physician oversight. ### CJC-1295 + Ipamorelin — Pulsatile GH Release Without Cortisol Spike Category: Peptides (GHRH + ghrelin agonist combination) CJC-1295 is a GHRH analog with a half-life extender; Ipamorelin is a selective ghrelin receptor agonist. Together they produce pulsatile, physiologic GH release without significant cortisol or prolactin elevation. The combination is the most-used growth hormone secretagogue stack in functional medicine. ### GHK-Cu Peptide for Skin and Hair — The Copper Peptide Encyclopedia Category: Peptides (Copper peptide, dermal regeneration) GHK-Cu is the most-studied copper peptide for skin regeneration and hair follicle stimulation. Available topically, via dermal microneedling, or compounded subcutaneously. NexLife's peptide therapy and hair health programs include GHK-Cu protocols. ### TB-500 (Thymosin Beta-4) — Recovery Stack Companion to BPC-157 Category: Peptides (Wound healing, recovery stack) TB-500 is a synthetic version of Thymosin Beta-4, the most abundant peptide in human platelets and the dominant peptide in wound healing. Frequently paired with BPC-157 in recovery protocols. NexLife's peptide therapy program covers TB-500 under physician oversight. ### Peptide Stacks 2026 — Recovery, Growth Hormone, and Longevity Combinations Category: Peptides (Recovery, GH, longevity combinations) Peptide stacking is the practice of combining 2–4 peptides to amplify a clinical effect — most commonly recovery (BPC-157 + TB-500), growth hormone (CJC-1295 + Ipamorelin), or longevity (Epithalon + MOTS-c). Stacking should always be under physician oversight, with attention to cumulative dose and washout periods.
