I'm a fan of hgh pro but I wanted to come post And bump this- I took one cap of powerful last night ( I have 3 sample packs) bc I have bad prolactin sides and blood work to show it elevated..... Let me say that a) i slept like a baby b) I woke up twice or three times with raging wood, something I have not had in months during sleep. I had some ED issues last weekend so I got blood work and prolactin was confirmed. I'm gonna run with this powerfull at 1-2 caps a day for 10-20 days depending on dosage and see how my next labs pan out and if I can get it up properly and reduce my puffy nipples
