Relaxin promotes growth of reproductive tissues…
Then it goes on to say they dont know how… But that they did find that a relationship exist between HR2 and IGF-1 and IGF-2.
This hits at my intuition… I suspect this not fully understood process of just how relaxin causes general morphological changes to genitalia is where IGF-1 and IGF-2 play a key role in this mystery process.
Thats why in my latest experiment I took a dose of 6.5mcg of PGE-1, waited to get hard then put on a rubber ring on after I injected 3cc’s of HR2, IGF-1 LR3, and IGF-2LR3. 1 cc of each.
HR2 is 1 vial 5mg into 20cc of Bac H20, IGF-1 is 100mcg in 10cc and IGF-2 is 1200mcg in 20cc. These are my concentrations.
Anyway after injected I put on the o-ring and pumped in warm bath water at 200 on the gauge for 15-20 minutes. Then after I got more limp after 1.5 hrs or so I put on my PeniMaster and pulled till bed time a few hours later…. No jelqs, no clamping save whilst pumping if you want to count that.
