Dose Range 100-300 mcg subcutaneous 1-3x daily (most commonly 200-300 mcg pre-bedtime); often combined with CJC-1295 without DAC at 100-300 mcg Frequency 1–3 times daily; most commonly once at bedtime Cycle Length 8–16 weeks; can be used long-term with periodic breaks Half-Life ~2 hours (plasma) ## Administration Routes subcutaneous intravenous (clinical only) ### Quick Reconstitution Calculator Calculate syringe units instantly Syringe Draw 10.0 units 2500 mcg/ml · 0.100 ml draw Full Tool (https://www.bodyhackguide.co/tools/reconstitution) For laboratory research use only. This tool performs reconstitution math (concentration and syringe-unit conversion) and is not dosing guidance for humans or animals. ## Dosing Protocols Beginner **Goal: learn the injection workflow and assess personal response before adding a stack partner.** **Standalone ipamorelin — weeks 1-4** - **Dose:** 200 mcg subcutaneous, once daily - **Timing:** Pre-bed, fasted (≥2 hours after last meal, no carbs before injection) - **Why fasted:** Elevated insulin and blood glucose blunt the GH response to any secretagogue. A fasted window is non-negotiable for proper dosing - **Site:** Abdominal subcutaneous fat, rotate sites (L/R of navel, ~2 inches from midline) - **Needle:** 29-31G × 1/2" insulin syringe - **Reconstitution:** 5 mg vial + 2 mL bacteriostatic water = 2.5 mg/mL; 200 mcg = 0.08 mL (8 units on a 1 mL syringe) - **Storage:** Refrigerate reconstituted vial; use within 30 days **What to track (weeks 1-4)** - Sleep quality (subjective 1-10 daily) - Morning recovery / soreness - Appetite in the evening (ghrelin effect) - Any head-heaviness, tingling, or injection-site reactions **Beginners should NOT**: - Combine with CJC-1295 / MOD-GRF 1-29 in week 1 (assess tolerance first) - Exceed 200 mcg per injection - Inject pre-workout or after meals **At week 4, reassess**: if tolerated well, progress to the intermediate stacked protocol. If poor response (no sleep improvement, minimal subjective effect), review injection technique and consider the intermediate protocol with the GHRH partner — which is where the real GH pulse amplitude comes from. Standard **Goal: exploit the GHRH × ghrelin synergy for maximal pulse amplitude. This is the standard biohacking configuration.** **Ipamorelin + MOD-GRF 1-29 (CJC-1295 without DAC) — 8 weeks** - **Ipamorelin dose:** 200 mcg SC - **MOD-GRF 1-29 dose:** 100 mcg SC (same injection — they can be drawn into the same syringe) - **Frequency:** 2x daily (pre-bed + morning fasted) OR 1x daily pre-bed - **Timing windows:** - **Pre-bed:** 2+ hours post-meal, within 30 min of lights-out — amplifies the natural nocturnal GH pulse - **Morning fasted:** immediately upon waking, 45-60 min before first meal — second pulse timed against low insulin/glucose - **Optional pre-workout:** 30-45 min before training, only if post-meal >2 hours (many users drop this dose because peri-workout injection can blunt the training-induced GH pulse) **Why 2x vs 1x daily** - 1x daily (pre-bed) = the conservative, sleep-focused protocol; most reported benefit for recovery and sleep - 2x daily (pre-bed + morning) = the "body composition" protocol; ~30% higher steady-state IGF-1 but also higher fluid retention **Cycling — 8 weeks on / 4 weeks off** The conservative default. Mechanistically, ipamorelin + MOD-GRF 1-29 do not produce the sustained receptor occupancy that drives tachyphylaxis, but the off-cycle supports: - Baseline HPA axis integrity - Insulin sensitivity recovery - IGF-1 washout **Bloodwork** - **Baseline:** Fasting glucose, HbA1c, IGF-1, testosterone, PSA (men >40), CBC, comprehensive metabolic panel - **Week 4:** Fasting glucose, IGF-1 - **End of cycle:** Full panel **Flags that require dose reduction or cessation** - IGF-1 above the age-adjusted reference range upper limit (generally >250 ng/mL in adults 30-50) - HbA1c rising >0.3 points within one cycle - Persistent peripheral edema or carpal tunnel symptoms - Fasting glucose consistently >105 mg/dL Advanced **Goal: maximize GH pulse density within the physiologic envelope. For experienced users with baseline labs and a longitudinal monitoring plan.** **Tri-daily ipamorelin + MOD-GRF 1-29 — 8-12 weeks** - **Dose per injection:** 100-200 mcg ipamorelin + 100 mcg MOD-GRF 1-29 - **Frequency:** 3x daily - Injection 1: Morning fasted (immediately upon waking) - Injection 2: Midday (45-60 min before lunch, fasted ≥2 hours) - Injection 3: Pre-bed (2+ hours post-meal) - **Rationale:** Each injection produces a discrete GH pulse; 3x/day roughly mimics the natural ~3-5 pulse/day frequency of the adult GH rhythm **Alternative advanced configuration: ipamorelin + tesamorelin** Tesamorelin is a 44-amino-acid stabilized GHRH analog FDA-approved for HIV-associated lipodystrophy. It has **longer GHRH-receptor occupancy** than MOD-GRF 1-29 and produces a more durable GH pulse. For visceral fat-focused protocols: - 100 mcg ipamorelin SC + 2 mg tesamorelin SC, once daily pre-bed - Stronger effect on visceral adiposity than MOD-GRF 1-29; higher cost; prescription-grade in the US **Stacking with exercise** The peri-workout dose is controversial. Training itself produces the largest endogenous GH pulse of the day (especially resistance training and HIIT); adding ipamorelin pre-workout can blunt this via negative feedback. Most advanced protocols skip the peri-workout injection or place it ≥4 hours from training. **Cycling considerations** - 12 weeks on / 4-6 weeks off is the upper-end biohacking protocol - Long-term (>6 months continuous) dosing is not well-characterized in healthy adults — users doing this should monitor bloodwork monthly, not quarterly - Full HPA and IGF-1 washout on the off-cycle helps confirm no tachyphylaxis or insulin-sensitivity drift **Contraindications specific to advanced dosing** - Any active malignancy (GH/IGF-1 axis may accelerate tumor growth) - Active diabetic retinopathy - Severe insulin resistance or uncontrolled T2DM - History of acromegaly or pituitary adenoma ## Weight-Based Dosing Typically 1–3 mcg/kg per injection. Standard flat dose of 200 mcg is suitable for most. ## Commonly Stacked With **Tier 1 — The "must-stack" pairing:** CJC-1295 / MOD-GRF 1-29 (https://www.bodyhackguide.co/compound/cjc-1295) at 100 mcg per ipamorelin injection. This is the canonical GHS stack. Same injection, same syringe. Without this pairing, ipamorelin produces a real but modest GH pulse; with it, the pulse is 3-5x larger and the protocol becomes meaningfully anabolic ([Bowers et al., 1991]). **Tier 2 — Synergistic body-composition stacks:** - **Semaglutide (https://www.bodyhackguide.co/compound/semaglutide) or Tirzepatide (https://www.bodyhackguide.co/compound/tirzepatide)** — for users on GLP-1 therapy pursuing body recomposition, ipamorelin + MOD-GRF 1-29 preserves lean mass during the caloric deficit. Time the GH secretagogue pulse opposite to the GLP-1 peak to avoid compounding appetite effects - **BPC-157 (https://www.bodyhackguide.co/compound/bpc-157) + TB-500 (https://www.bodyhackguide.co/compound/tb-500)** — the "healing stack". GH/IGF-1 elevation accelerates collagen synthesis that BPC-157 and TB-500 enable. Particularly useful for tendon / ligament rehab - **Testosterone (TRT) or clomiphene** — the HPG and GH axes are complementary; combined use is the standard in integrative hormone optimization clinics - **NAD+ (https://www.bodyhackguide.co/compound/nad) / NR / NMN** — mitochondrial co-factor support for the protein-synthesis demand created by elevated IGF-1 **Tier 3 — Advanced / selective stacks:** - **Epithalon (https://www.bodyhackguide.co/compound/epithalon)** — longevity-framed stack combining GH axis amplification with telomere / pineal support - **GHK-Cu (https://www.bodyhackguide.co/compound/ghk-cu)** — skin / connective tissue regeneration synergy **DO NOT stack:** - **Other ghrelin-receptor agonists** (GHRP-2, GHRP-6, hexarelin, MK-677) — redundant at the receptor; no additive benefit; stacks the side-effect burden (GHRP-2/6 elevate cortisol and prolactin) - **Exogenous recombinant GH (Somatropin)** — defeats the purpose; somatropin directly replaces GH, bypassing the pituitary pulse mechanism ipamorelin enables. Use one or the other **Timing alignment:** Ipamorelin and MOD-GRF 1-29 can be drawn into the same syringe and injected together — the peptides are chemically compatible in BAC water for the brief period between draw and injection. For multi-compound stacks (ipamorelin + MOD-GRF + BPC-157), use separate injection sites — BPC-157 is dosed differently (often daily) and benefits from local rather than systemic delivery. ## Side Effects & Safety Ipamorelin has the **cleanest side-effect profile** of any ghrelin-receptor agonist, which is why it dominates modern biohacking protocols. The profile is driven by (a) selective GHS-R1a agonism without cross-receptor activity, and (b) acute GH elevation (the same side effects any GH-secretagogue produces). **Common (>10% of users, usually mild and transient)** - **Injection site reactions** - erythema, pruritus, mild pain; resolves within hours, mitigated by injection site rotation and proper reconstitution technique - **Mild fatigue or head-heaviness 10-30 min post-injection** - thought to reflect the acute GH pulse; typically subsides within an hour - **Transient hunger / appetite increase** - direct ghrelin-receptor effect on hypothalamic feeding neurons; much less pronounced than GHRP-6 because ipamorelin's shorter duration limits tonic appetite stimulation - **Vivid dreams or altered sleep architecture** - usually a positive effect (deeper SWS); occasionally reported as disruptive in the first week **Uncommon (1-10%)** - **Water retention / mild peripheral edema** - dose-dependent GH effect; usually visible at doses >400 mcg per injection or >3 injections/day - **Transient tingling / paresthesias in hands** - early sign of water retention / peripheral compression; resolves with dose reduction - **Joint stiffness or achiness** - IGF-1-mediated; typically appears 2-4 weeks into dosing as steady-state IGF-1 rises - **Headache** - usually mild; typically resolves with continued dosing or hydration **Rare but important** - **Insulin resistance / elevated fasting glucose** - all GH-elevating therapies impair glucose tolerance; typically not clinically significant at biohacking doses (100-300 mcg) but can become measurable at >600 mcg/day or with prolonged use. Diabetics and pre-diabetics should monitor HbA1c - **Carpal tunnel symptoms** - fluid-shift-mediated; resolves on cessation - **Hypersensitivity reactions** - rare but documented; usually to a residual contaminant or preservative rather than ipamorelin itself **What ipamorelin does NOT do (in contrast to other GHS peptides)** - Does NOT elevate cortisol ([Raun et al., 1998](https://pubmed.ncbi.nlm.nih.gov/9849822/), shown in swine) - Does NOT elevate prolactin (important for men concerned about gynecomastia on other GHS peptides) - Does NOT elevate ACTH - Does NOT affect gonadotropins (LH, FSH) or TSH - Does NOT cause the "mega-hunger" of GHRP-6 (tonic ghrelin activation) - the short duration keeps appetite effects transient **Long-term uncertainty** The ipamorelin evidence base is short-duration - the longest human exposure on record is ~7 days, in the Beck 2014 post-operative ileus trial (which did not meet its efficacy endpoint). Biohacking use at 200-300 mcg/day for 3-6 months is extrapolated from pharmacology, not validated. Unknowns include: - Chronic effects on insulin sensitivity - IGF-1-related cancer risk (the GH/IGF-1 axis is implicated in some epithelial cancers; no ipamorelin-specific data) - Pituitary somatotroph response to long-term dosing (tachyphylaxis is theoretical but not well-characterized) **Users should monitor**: fasting glucose, HbA1c, IGF-1 (baseline and 4-6 weeks), PSA (men >40). Cycle protocols (8 weeks on / 4 weeks off) are the conservative approach although the mechanistic need for cycling is debated. Contraindications **Absolute contraindications** - **Active malignancy** — GH and IGF-1 are trophic factors for multiple cancer cell lines. While ipamorelin-specific cancer data does not exist, the GH/IGF-1 axis is implicated in colorectal, prostate, breast, and hepatocellular cancer progression ([Renehan et al., 2004]). Do not use during active cancer treatment or within 5 years of complete remission without oncologist clearance - **Known or suspected pituitary tumor / acromegaly** — superimposing exogenous secretagogue on an already-hyperactive somatotroph axis can accelerate tumor growth and precipitate acromegalic complications - **Active diabetic retinopathy** — GH elevation can worsen proliferative retinopathy; absolute contraindication until retinopathy is stabilized - **Pregnancy or breastfeeding** — no safety data; do not use - **Age <18** — no pediatric safety data; pediatric GHD is managed with prescription GHRH analogs (sermorelin) under endocrinology supervision, not biohacking protocols **Relative contraindications (consult physician before use)** - **Type 2 diabetes or pre-diabetes** — GH elevation impairs insulin sensitivity; use requires careful glucose monitoring and may accelerate progression in borderline cases - **Uncontrolled hypertension** — fluid retention can exacerbate blood pressure - **History of carpal tunnel syndrome** — fluid retention and connective tissue expansion can worsen symptoms - **Hypothyroidism** — thyroid status affects GH axis; optimize thyroid first - **History of pituitary or hypothalamic surgery or radiation** — altered GHRH/ghrelin receptor status; unpredictable response **Drug interactions** - **Insulin and oral hypoglycemics** — ipamorelin's effect on glucose tolerance may require dose adjustments of antidiabetic medications - **Corticosteroids** — chronic systemic corticosteroids suppress the GH axis and blunt ipamorelin response - **Recombinant GH (Somatropin)** — redundant; do not combine - **Other GHS peptides** — do not stack (see stacking notes) **Monitoring requirements for users** - **Baseline labs:** Fasting glucose, HbA1c, IGF-1, complete metabolic panel, CBC, PSA (men >40), full thyroid panel - **4-6 weeks into dosing:** Fasting glucose, IGF-1 (confirm within age-appropriate range) - **End of each cycle:** Full panel; look for HbA1c creep, PSA changes, IGF-1 elevation above age-adjusted ULN **Discontinuation criteria** Stop ipamorelin and consult a clinician if you develop: - Persistent peripheral edema or facial swelling - New or worsening carpal tunnel symptoms - IGF-1 levels >300 ng/mL (supraphysiologic in most adults) - Fasting glucose persistently >110 mg/dL or HbA1c rising >0.4 points - Any new palpable mass, changing mole, or unexplained weight loss (cancer workup indicated) - Severe headache, visual changes (rule out pituitary pathology) Check interactions with the Interaction Checker → (https://www.bodyhackguide.co/tools/interaction-checker) ## Additional Notes **Standard therapeutic range:** 100-300 mcg SC per injection, 1-3x daily. **Dose-response is roughly linear from 50 mcg to 300 mcg IV** ([Gobburu et al., 1999]). Above 300 mcg, GH pulse amplitude plateaus while side effect burden (fluid retention, hunger, paresthesias) rises. **More is not better** past ~300 mcg per injection — run more frequent smaller pulses instead if you want higher total exposure. **Fasted state is non-negotiable.** Elevated insulin suppresses GH release through multiple mechanisms (increased somatostatin tone, reduced somatotroph sensitivity). Post-meal dosing can reduce GH pulse amplitude by 50-70%. The two reliably fasted windows: - Pre-bed (2+ hours post-meal, evening meal finished by 7pm for a 9pm injection) - Morning wake (before first food) **Dose scaling by goal** - **Sleep and recovery focus:** 200 mcg pre-bed, 1x daily, no stack partner required (though MOD-GRF 1-29 amplifies effect 3-5x) - **Body composition:** 200 mcg + 100 mcg MOD-GRF 1-29, 2x daily (pre-bed + morning fasted) - **Connective tissue / injury recovery:** 300 mcg + 100 mcg MOD-GRF 1-29, 2-3x daily, often stacked with BPC-157 (https://www.bodyhackguide.co/compound/bpc-157) and TB-500 (https://www.bodyhackguide.co/compound/tb-500) **Dose conversions** - 5 mg vial + 2 mL BAC water = 2.5 mg/mL (2500 mcg/mL) - 100 mcg = 0.04 mL = 4 units on a 1 mL insulin syringe - 200 mcg = 0.08 mL = 8 units - 300 mcg = 0.12 mL = 12 units See the Reconstitution Tool (https://www.bodyhackguide.co/tools/reconstitution/ipamorelin) for any vial size / BAC water combination. **Interactions with nutrition** - Carbohydrates and protein both elevate insulin, blunting GH response - Caffeine does not interfere and may amplify the SWS effect - Alcohol suppresses GH secretion independently and synergistically blunts ipamorelin effect — avoid within 4 hours of dosing Where to Buy Ipamorelin Compare 5 listings across 3 vendors, from $24.99 https://www.bodyhackguide.co/compound/ipamorelin ## Frequently Asked Questions What is the recommended Ipamorelin dosage?
