IGF-DES-2X
XENE BIOLABS RESEARCH SERIES
FOR RESEARCH USE ONLY
Category: Growth Factor | Half-life: 20-30 min
Mechanism
Mechanism
DES variant of IGF-1 with N-terminal truncation. 10x more potent than IGF-1 LR3 for acute muscle hyperplasia. Binds muscle cells directly, bypasses IGFBP.
Dosing Protocol
Reconstitution: 1 mg + 1 mL BAC = 1000 mcg/mL. 20 mcg = 0.02 mL = 2 units.
Critical: Take immediately post-training into muscles worked. Must have carbs intra/post.
IGF-1 DES
IGF-DES-2X | IGF-1 Truncated Variant — Local Anabolic | CAS: N/A
IGF-1 DES (des 1-3 IGF-1) is a truncated form of IGF-1 lacking the first three N-terminal amino acids. This structural change
reduces IGFBP binding affinity by ~10x, making it significantly more potent than standard IGF-1 in local tissue. It does not
bind carrier proteins, so effects are predominantly local/site-specific. Short half-life — must be injected at target tissue.
DOSING PROTOCOL.
| Parameter | Details |
|---|---|
| Dose | 50–150 mcg per injection, IM at target muscle |
| Frequency | 1–2x daily; immediately pre or post-workout |
| Cycle Length | 4 weeks on; 4 weeks off |
STACKING RECOMMENDATIO
Complement with PEG-MGF for full IGF pathway coverage. HGH 191AA provides upstream substrate. BPC-157 for
connective tissue protection under anabolic load.
NOTE: Site-specific — inject into target muscle only. Very short acting. Hypoglycemia risk at higher doses — have glucose on hand. Not
for systemic use.

XENE BIOLABS RESEARCH SERIES
FOR RESEARCH USE ONLY
Category: Growth Hormone | Half-life: 20-30 min SubQ, 3.5h IV
Mechanism
Identical to endogenous GH. Binds GH receptor → IGF-1 release, lipolysis, anabolism, glucose regulation.
Dosing Protocol
Reconstitution: 10 IU + 1 mL BAC = 10 IU/mL. 2 IU = 0.2 mL = 20 units.
Critical: Monitor glucose, IGF-1, TSH. Can cause insulin resistance, carpal tunnel, edema at high doses.
PEG MGF-2X
XENE BIOLABS RESEARCH SERIES
FOR RESEARCH USE ONLY
Category: Muscle Growth Factor | Half-life: 48-72h due to PEGylation
Mechanism
Splice variant of IGF-1 expressed after mechanical stress. Activates satellite cells for muscle repair and growth. PEGylation extends half-life vs MGF.
Dosing Protocol
Reconstitution: 2 mg + 2 mL BAC = 1 mg/mL. 200 mcg = 0.2 mL = 20 units.
Critical: Never use on training days. IGF-1 competes with MGF. Use on rest days only.
