01Mechanism of Action

Parameter

Epitalon

IGF-DES

Primary target

Telomerase activity (proposed); pineal melatonin axis modulationKhavinson 2003

IGF-1 receptor (IGF1R)Shields 2007

Pathway

Activation of telomerase reverse transcriptase (hTERT) in somatic cells; pineal-axis modulation supports endogenous melatoninKhavinson 2003

IGF1R activation → PI3K/Akt & MAPK signaling → protein synthesis, proliferation

Downstream effect

Telomere elongation, improved sleep architecture, reported lifespan extension in aged miceKhavinson 2003

Enhanced muscle protein synthesis, myoblast differentiation, reduced apoptosis, cell proliferation

02Dosage Protocols

Parameter

Epitalon

IGF-DES

Standard dose

5–10 mg / day for 10–20 days, 1–2× per yearKhavinson 2003

Anecdotal community protocol. Russian clinical literature uses similar cycling.

—

Frequency

Once daily during a cycle

Variable — daily to multiple times daily in research

Lower / starter dose

2.5 mg / day

—

Evidence basis

In-vitro telomerase + Russian clinical trialsKhavinson 2003

Animal models + in vitro only

Duration

10–20 day cycles, 1–2× per year

—

Reconstitution

Bacteriostatic water

—

Timing

Pre-sleep preferred (pineal alignment)

—

Half-life

Hours (estimated)

Shorter than IGF-1 due to reduced IGFBP binding

Rapid tissue uptake, limited systemic circulation.

Research dose range

—

10–100 ng/mL (in vitro); μg doses (animal models)

Highly context-dependent; no standardized human protocol.

Route

—

Subcutaneous or intramuscular (local injection favored)

Local delivery maximizes tissue-specific uptake.

Human data

—

None — no clinical trials

03Metabolic / Fat Loss Evidence

Parameter

Epitalon

IGF-DES

Primary mechanism

—

Indirect via muscle hypertrophy → metabolic rate elevation

Direct lipolysis

—

Minimal evidence — IGF-1 axis primarily anabolic, not lipolytic

Prostate model

—

Inhibited BPH cell proliferation when combined with vitamin D3 analogueCrescioli 2002

Context-specific anti-proliferative effect, not fat loss.

Expected — erythema, irritation, local swelling

Sleep architecture

Cancer risk

Theoretical via telomerase activation in pre-malignant cells

—

Long-term safety

—

Pregnancy / OB

—

Hypoglycemia risk

—

Theoretical — IGF-1 axis enhances glucose uptake

Mitogenic risk

—

Chronic IGF-1 receptor activation may promote cell proliferation, potential tumor growthCrescioli 2002

Edema / Fluid retention

—

Possible via sodium retention (IGF-1 axis effect)

Human safety data

—

Absent — no human trials, all effects theoretical or extrapolated

Unknown long-term effects

—

No chronic dosing studies in humans; endocrine, metabolic consequences unknown

05Administration Protocol

Parameter

Epitalon

IGF-DES

1. Reconstitution

Add 1–2 mL bacteriostatic water to 10 mg vial → 5–10 mg/mL.

Des(1-3)IGF-1 has no approved human protocol. All administration details are derived from animal or in vitro research and should not be construed as medical guidance.

2. Injection site

SQ — abdomen preferred. Rotate sites.

Sterile water or bacteriostatic water per research protocol. Gently swirl; do not shake. Store reconstituted peptide at 2–8 °C.

3. Timing

Pre-sleep preferred to align with pineal axis.

Subcutaneous (abdomen, thigh) or intramuscular (deltoid, vastus lateralis). Local injection to target tissue (e.g., muscle group) may enhance regional uptake.

4. Storage

Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.

Frequency and timing vary by research design. Post-exercise or fasted state may theoretically enhance muscle uptake.

5. Needle

29–31G, 4–8 mm insulin syringe.

27–31G insulin syringe for subcutaneous; 25–27G for intramuscular.

6. Monitoring

—

Glucose monitoring essential (hypoglycemia risk). No established IGF-1 or safety labs for human use.

IGF-DES

+ BPC-157

Moderate

View BPC-157 →

Des(1-3)IGF-1 promotes myoblast differentiation and protein synthesis, while BPC-157 enhances tissue repair, angiogenesis, and collagen synthesis. Both act on distinct pathways (IGF1R vs gastric pentadecapeptide mechanisms) to support muscle recovery and connective tissue integrity. Synergy is mechanistic but lacks direct co-administration studies.

Des(1-3)IGF-1: Research dose post-workout (local IM)
BPC-157: 250–500 mcg SQ, daily or twice daily
Frequency: Daily or per research protocol
Primary benefit: Accelerated muscle repair, enhanced hypertrophy, connective tissue support

+ TB-500

Moderate

View TB-500 →

TB-500 (Thymosin Beta-4 fragment) promotes cell migration, angiogenesis, and wound healing via actin regulation. Des(1-3)IGF-1 drives protein synthesis and myoblast proliferation. Combined, these peptides may synergistically enhance muscle recovery, repair, and hypertrophy through complementary anabolic and regenerative pathways. No direct human co-administration data.

Des(1-3)IGF-1: Research dose post-workout (local IM)
TB-500: 2–5 mg SQ, 2× weekly
Frequency: Per research cycle
Primary benefit: Muscle hypertrophy, injury recovery, vascular support
