Just started week 5. Closer to an itch than a sting. I'm not very consistent with dosing but it works out to 1-2 mg a day.
I have gained a pound or two over the past four weeks and doubled my reta over the same time. Harder to keep a deficit lately which might be related.
I take a blend with Ipa and ten minutes after the shot my stomach grumbles. It goes away within a half hour at the most, but I'm pretty sure that's the ghrelin mimicking property of ipa.
I'm lifting just after morning injection and on those three days, I often take another smaller dose before bed. If so, I occasionally skip the next day entirely (In addition to the weekend day I skip anyway.) I starting to see definite gains, but I've seen quick gains before when starting a weight training routine. Still I think it helps.
Initially, I felt sharper. Semax let me down, but Tesa/Ipa is noticeable in the mental clarity improvement. I don't know if I have gotten used to it lately or if it was a temporary effect, but I do think I get more done whether I feel it or not.
