Explore MGF Without PEG dosage trends, reconstitution volumes, and vial size patterns from anonymized WPA peptide calculator data.
"MGF Without PEG" is the unmodified synthetic mechano growth factor C-terminal E-peptide — the same primary sequence as the commercial "PEG-MGF" product but without the polyethylene-glycol conjugation used to extend plasma half-life. Mechanistically, biologically, and in terms of human evidence it is the same molecule as the entry above for MGF IGF-1 Ec; the only difference is pharmacokinetic.[1][2]
Identical to the synthetic MGF E-peptide described in the MGF IGF-1 Ec entry: putative IGF-1R-independent activation of myoblast proliferation, with the molecular identity of a separate "MGF receptor" still contested in the literature.[2][4]
No regulatory approvals. Research use only, with the same pre-clinical muscle-regeneration literature as MGF IGF-1 Ec.[1][2][3] **Typical dose:** No human dose has been established. The plasma half-life of unmodified MGF E-peptide in rodents is reported in minutes, which is the reason the pegylated variant exists; in practice the unmodified form is rarely used outside of academic cell-culture and short-duration rodent injection studies.[2]
Research peptide. No human trials of unmodified synthetic MGF E-peptide have been published.
MGF Without PEG has a reported half-life of ~5–7 min. The pharmacokinetic reference models an interval of once daily (post-workout, local); this is not a measured community cadence or a dosing recommendation. Without pegylation MGF is cleared within minutes — far faster than PEG-MGF — so it acts as a brief local pulse and is dosed close to training. Pharmacokinetic source: Pre-clinical MGF pharmacokinetic estimates. It is catalogued under Muscle Peptides on WPA.
The WPA community has not yet logged enough MGF Without PEG calculator sessions to publish dose, vial size, or bacteriostatic water distributions for it. This page therefore covers what is known about the compound itself; the usage charts fill in as researchers run the calculator.
These figures come from anonymized WPA peptide calculator sessions, not verified administrations or unique people. Separate modal inputs do not establish a joint protocol. They are community input statistics — not dosing recommendations, and not medical advice.
